v2.2.0 (30 Sep 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Tartube is now confirmed to work on MacOS. See the README file for
    installation instructions
- Tartube can now handle video thumbnails in the .webp format, as long as
    FFmpeg is installed. Thumbnails are automatically converted to .jpg (either
    by youtube-dl, or by Tartube itself, as appropriate). This only affects new
    downloads. If you want to convert .webp thumbnails you've already
    downloaded, click Operations > Tidy up files..., select 'Convert .webp
    thumbnails to .jpg using Ffmpeg', and click OK. (This procedure may take a
    while if there are thousands of thumbnails to convert) (Git #155 and
    others)
- Thumbnails, video description, metadata and annotation files can now be
    downloaded into a sub-directory, rather than being stored in the same
    directory as their videos. Thumbnails are stored in /.thumbs, and the
    others are stored in /.data. On Linux/BSD, those sub-directories are
    normally invisible by default (typically, pressing CTRL+H will reveal
    them). This new feature is disabled by default. To enable it, click Edit >
    Download options... > Files > Write/move files, and select one or more of
    the checkboxes. The new feature only affects new downloads. If you want to
    move files you've already downloaded, click Operations > Tidy up files...,
    select 'Move thumbnails into own folder' and/or 'Move other metadata files
    into own folder', and click OK (Git #139)
- You can now select one or more videos, and process them with FFmpeg directly
    (in other words, after downloads have finished, and without involving
    youtube-dl). This will be useful if you want to convert one video format to
    another, change the frame rate, or with countless other tasks. Just select
    the video(s), right-click them and select 'Process with FFmpeg...'. Since
    many FFmpeg procedures require a different output filename, you can specify
    that, too. Note that FFmpeg sometimes takes a very long time; you should
    test a procedure with a single video, before trying to process hundreds of
    them (Git #153)
- Tartube can now use forks of youtube-dl, such as youtube-dlc. (Tartube
    assumes that a fork is still very similar to the original). A fork can be
    specified in Edit > System preferences... > youtube-dl (Git #158)
- New installations of Tartube will now auto-detect the location of youtube-dl,
    if it is already installed on your system. This will benefit users of the
    .DEB and .RPM packages, who until now were expected to know how to set the
    youtube-dl path manually (Git #152)
- Ffmpeg and AVConv will now also be auto-detected. If you have installed them
    in unusual locations, you should specify those locations in Edit >
    System preferences... > youtube-dl > Ffmpeg / AVConv. If not, there is no
    need to specify either location; just leave the boxes empty. (None of this
    applies to MS Windows users)
- When Tartube shuts down unexpectedly, it doesn't have time to mark the
    database as no longer being in use (i.e. doesn't remove the lockfile). The
    next time Tartube runs, users were prompted to remove the lockfile, then
    restart Tartube. Many users were unhappy with this situation, so it has
    been improved. You will still be prompted to remove the lockfile, but there
    is no longer any need to restart Tartube

MINOR NEW FEATURES
- FFmpeg is now required for a lot of Tartube functionality. On new
    installations, users who have not yet installed FFmpeg will see some
    additional nag-boxes, and various hints in other configuration windows
    (Git #155)
- If users downloadd a video, but only its audio, the video appeared in
    Tartube's database as downloaded. However, when the user clicked on the
    'Player' label, the audio file was not opened in the system's media player.
    Tartube now checks for an audio file (as well as video files in different
    formats), if the video file it was expecting does not exist
- When the user clicks Operations > Update youtube-dl, Tartube now
    automatically makes the Output tab visible. Hopefully this will avoid
    confusion for new users, who do not notice that the Check all/Download all
    buttons have been greyed out. This behaviour can be disabled, if required:
    click Edit > System preferences... > Output > Output Tab, and deselect
    'During an update operation, automatically switch to the Output Tab'
    (Git #149)
- The invidio.us website has closed. There are many mirrors available. Tartube
    now uses invidious.site as its default mirror. To specify a different
    mirror, click Edit > System preferences... > Operations > Downloads
- YouTube phased out video annotations in 2019. The Tartube code was unable to
    download annotation files during a simulated download (for example, with
    the 'Check all' button). Now that there is no way of testing any fix, the
    feature has been removed entirely
- You can now add automatic custom downloads on a schedule (normal downloads
    were already available). Click Edit > System preferences... > Scheduling
    (Git #154)
- Reduced the compulsory delay at the end of many types of operation. The
    delay time is not the same for all types of operation
- Tartube debug messages are visible in the terminal window (if open). Before,
    the user had to edit the source code to enable debug messages. They can
    now be enabled from within Tartube itself: click Edit > System
    preferences... > General > Debugging. These settings are not saved, so when
    Tartube restarts, you will have to re-enable debug messages again
- In the Progress and Classic Mode tabs, the name of the incoming file (and
    other similar columns) are no longer artificially shortened (Git #161)

MAJOR FIXES
- When one channel downloads into videos into another channel's directory,
    and the other channel is then deleted, the Tartube database did not update
    itself properly. Fixed
- Fixed some issues when using the refresh operation to import videos, that had
    been downloaded by youtube-dl (without Tartube's) help, into Tartube's
    database (Git #142)
- Tartube can now download videos using the youtube-dl archive file, even when
    missing video detection is turned on (Git #154)
- Tartube sometimes froze on shutdown, after youtube-dl had been updated.
    Applied the existing MS Windows fix to all operating systems

MINOR FIXES
- Fixed issues when importing a JSON export file on MS Windows, and a different
    issue error when importing it on Linux
- We were not able to fix export issues reported in Git #143, but we have
    updated the dialogue window, which should give more information about what
    is causing the error
- System folders cannot be deleted. The 'Delete folder' popup menu item is now
    greyed out. (Nothing happened, even when it was clickable)
- Warnings about broken Gtk have been removed (probably permanently)

v2.1.070 (8 Aug 2020)
-------------------------------------------------------------------------------

MAJOR FIXES
- Checking videos (e.g. by clicking the Check All button) was broken. Fixed
- Fixed a very rare freeze/crash when handling temporary directories

v2.1.065 (7 Aug 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Tartube can now detect videos that were downloaded by the user, and have
    since been removed by the original uploader. To enable this functionality,
    click 'Edit > System preferences... > youtube-dl > Preferences' and then
    click 'Add videos which have been removed from a channel/playlist to the
    Missing Videos Folder' to select it. Note that youtube-dl's archive file
    (if enabled) is ignored when missing video detection is enabled (Git #140)

MINOR NEW FEATURES
- Schedules download times can now be specified in any time unit (for example,
    minutes), rather than in days only (Git #129)
- The Tartube version number is no longer displayed in the main window's title
    bar (this was only supposed to be a temporary feature)

MAJOR FIXES
- In the Classic Mode tab, the video/audio format selector was broken. It was
    not possible to change the video/audio format from here. Fixed (Git #124)
- It was not possible to perform a custom download by right-clicking a channel
    or playlist. Fixed (Git #134)

MINOR FIXES
- Added .ICO file for the Tartube logo, for MS Windows users (Git #122)
- The first entry box in the download options window was editable. Fixed

v2.1.051 (4 Jul 2020)
-------------------------------------------------------------------------------

ATTENTION YOUTUBE USERS
- You may be wondering why Tartube cannot display video thumbnails from
    newly-uploaded videos. YouTube has changed its video thumbnails to a new
    format, .webp. The Gtk graphics libraries don't support this format. A
    future release of youtube-dl will convert .webp thumbnails to .jpg, but the
    feature is not available yet. When it becomes available, you might need to
    install Ffmpeg on your system, if you haven't already done so (see the
    README file)

MAJOR NEW FEATURES
- For MS Windows users, there is now a portable edition of Tartube, as well as
    the usual installer. Use the portable edition if you want to run Tartube
    from removable media, such as a USB drive
- After clicking the main 'Check all' button, it was not possible to right-
    click a video to download it. After clicking the main 'Download all'
    button, it was not possible to right-click a video to check it. Both of
    these actions are now allowed
- Closing Tartube to the system tray is now disabled by default (only affects
    new installations). This is for the benefit of users whose systems do not
    have a system tray, or for whom the Tartube icon is not visible for some
    reason (Git #98)

MINOR NEW FEATURES
- The latest releases of Tartube's graphics library, Gtk, still do not fix the
    many stability issues we've been reporting for some years. As a consequence
    the workarounds that stop Tartube from crashing every two minutes are now
    completely optional (i.e. Tartube no longer applies them regardless of your
    wishes). If you enjoy watching Tartube crash, feel free to disable the
    workarounds by clicking 'Edit > System preferences... > General
    > Stability' and then clicking 'Disable some cosmetic features...' to
    deselect it
- When checking the status of livestreams (which happens every few minutes,
    by default), the Tartube icon in the system tray now looks different. (The
    checks for livestream status were otherwise silent)
- Various alternative front-ends to YouTube exist. Tartube already recognises
    HookTube and Invidious. You can now specify any alternative you like;
    perhaps one the several Invidious clones that are currently available.
    Click 'Edit > System preferences... > Operations > Custom' to open the
    correct tab. More complete instructions have been added to the README
- In the Classic Mode tab, the buttons in the top-right corner have been
    replaced with a popup menu
- A separate set of download options are now applied to downloads in the
    Classic Mode Tab. These download options are applied by default, even on
    existing installations. To disable/re-enable them, click the menu in the
    top-right corner of the tab, and select 'Use classic download options' or
    'Use general download options'
- If download options are applied to the Classic Mode tab, then a video's
    description, metadata (etc) files are not downloaded in that tab, by
    default (Git #77)
- The youtube-dl archive file is no longer created in downloads from the
    Classic Mode tab, by default. To re-enable this functionality, click 'Edit
    > System preferences... > youtube-dl', and select both 'Allow youtube-dl to
    create its own arhive file...' and 'Also create an archive file when
    downloading from the Classic Mode tab...'. This change affects new
    installations; users with earlier versions of Tartube installed on their
    system must remove an existing archive file manually,  if they don't want
    it (Git #77)
- In the Classic Mode tab, added a button to show the contents of the download
    directory/folder
- In the system preferences window, the 'When Tartube starts, automatically
    open the Classic Mode tab' setting has been moved to a more logical place
    (Windows > Tabs)
- The toolbar at the top of the Videos tab can now be hidden, if you don't
    like it. Click 'Edit > System preferences... > Windows > Main window', and
    click 'Don't show the main window toolbar' to select it
- In the Videos tab, you can now add the URL of a video, channel or playlist to
    the Classic Mode tab by right-clicking it, and then selecting an item in
    the popup menu. The original video/channel/playlist is not removed from
    Tartube's database
- Tidy operations can now remove .webp thumbnails. Once the youtube-dl fix
    mentioned above has been released, you can remove the thumbnails, then
    click 'Check all' to re-download them in .jpg format
- Some users have reported that some icons in Tartube's main window are
    invisible on their system. These are stock icons which should be available
    on all systems (but which, apparently, are not). For the benefit of those
    users, an extra set of icons have been created. To enable them, click
    'Edit > System preferences... > Windows > Main window > Replace stock icons
    with custom icons...' (Git #118)
- In the Temporary Videos folder, you can now see which channel/playlist/folder
    the video originally belonged to (where appropriate). The video's original
    name and description are also now visible, when known
- The URL for a channel or playlist can now be modified (Git #117)

MAJOR FIXES
- Installation via PyPI was broken, because the gi package had been removed.
    This is now fixed
- Installation using the DEB package will now automatically install
    python3-pip (if not already installed), so that youtube-dl can be
    installed/updated straight away
- When closing Tartube using the X button (usually) in the top-right corner of
    the window, and assuming that closing to the system tray is disabled,
    neither the config file nor Tartube's database file were saved. Fixed
- Adding a preferred media format in one download options window added the
    same format in all download options windows. Fixed (Git #119)
- A custom location for the FFmpeg executable can be set in 'Edit > System
    preferences... > youtube-dl'. This did not work on any operationg system
    for various reasons, all of which have been fixed (Git #90)
- After checking/downloading videos, Tartube checks for livestreams, after
    which it occasionally crashes. This crash has now been fixed
- Some videos were continually re-marked as livestreams, even after the
    livestream had finished broadcasting (and even after the user manually
    marked the video as not a livestream). Fixed
- Some livestream videos were continually re-added to Tartube's database,
    creating a number of duplicate copies of the same video. The problem has
    been fixed; you can delete the duplicates at your leisure
- When videos are checked, Tartube no longer supplies youtube-dl with a
    preferred media format. If you have specified a rarely-used media format,
    this change will prevent a great many useless error messages being
    generated
- When detecting livestreams, Tartube generated many 'Add livestream failed
    sanity check' errors. The underlying cause has been fixed, which should
    improve livestream detection a little

MINOR FIXES
- Fixed failure to recognise that a config file exists in the Tartube source
    code directory (which forces Tartube to use that location for its config
    file rather than the system's default location, even if the config file is
    empty or unreadable)
- Fixed rare problems in updating old Tartube database files to make videos
    work as livestreams. The database integrity check ('Edit >
    System preferences... > Filesystem > DB Errors') now checks for such
    problems
- In the download options window, the 'If a merge is required after post-
    processing, output to this format' option will not work if the specified
    media format doesn't also appear in the preferred format list. Moved the
    two onto the same tab, and added a dialogue window to warn the user that a
    media format must be added twice
- Also fixed the format selection combobox in the Classic Mode tab, so that
    the preferred media format and the 'If a merge is required after post-
    processing...' options are set to the same value
- In the system preferences window, the 'When Tartube starts, automatically
    open the Classic Mode tab' setting was not working properly; fixed it
- For downloads in the Classic Mode tab, an error was displayed in the
    Errors/Warnings tab using the video name 'Dummy Video'; changed that to
    the standard text for videos whose name is not known
- Fixed python errors generated when playing a sound effect, on a system for
    which the python playsound module hasn't been installed
- Fixed a python error generated when shutting down Tartube suddenly, while
    livestreams are being detected
- For reasons not understood, Tartube might (on extremely rare occasions)
    create a (red) system folder called 'downloads_2'. This folder could not be
    deleted. Until the cause can be found, such invalid system folders can now
    now be deleted, and are deleted automatically during a database integrity
    check
- In the system preferences window, Operations > Livestreams tab, there are two
    checkbuttons enabling/disabling livestream detection. The second one could
    be enabled even when the first was disabled; this has been fixed, and
    should remove some unexpected behaviour
- When updating youtube-dl, the warning 'The script youtube-dl is installed...'
    is now intercepted, and is no longer interpreted as a failure

v2.1.0 (7 May 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- For everyone who wants a simpler way to download videos, a new Classic Mode
    Tab has been added, emulating the look and feel of youtube-dl-gui. Videos
    downloaded in this tab can be downloaded to any location, and are not added
    to Tartube's database
- Tartube can now detect livestreams, and alert you when they start. This
    feature is EXPERIMENTAL, has only been tested on YouTube, and may not be
    reliable. It does not work at all on the 32-bit MS Windows installer
- Added internationalisation. If you can contribute a translation to this
    project, please see the ../docs/translate.rst file. As a proof of concept,
    Tartube can now be used with either British or American spelling
- You can now specify unlimited numbers of video/audio formats (the limit was
    previously three). You can also specify that youtube-dl should try to
    download each video in each of your preferred formats, rather than in one
    or all available formats (as was the case before)

MINOR NEW FEATURES
- Made minor improvements to the look of various dialogue windows
- Slightly improved the functionality of buttons in the system preference
    window's database tab
- If a database can't be loaded (but an alternative database can), an
    explanatory messages is now added to the Errors/Warnings Tab. If an
    alternative database can't be loaded (or only one database has been added
    to Tartube's list), then the dialogue window seen by the user is now
    slightly more helpful
- Some startup errors, which were invisible to users not running Tartube from a
    terminal window, now produce a visible dialogue window
- The code to force renamig of channels/playlists/folders (when required) has
    been adjusted so it creates a name like 'Folder_3' rather than
    'Folder_2_2_2_2'
- Instructions for Tartube installations have been updated generally. The
    MS Windows batch/shell files used to start Tartube have been tweaked

MAJOR FIXES
- The MS Windows installers have been updated to use Python 3.8. This may fix
    some stability issues for a few users
- For systems with a broken Gtk library (or if the user has disabled minor
    cosmetic features anyway), the list of videos in the Videos Tab is no
    longer updated during a download operation. This should resolve some
    lingering stability issues. (You can manually update the list by selecting
    a different channel/playlist/folder, then selecting the original one again)
- In the Video Catalogue, new videos are sometimes added to the last page,
    rather than to the first one. Rewrote the code yet again to resolve this
    issue; hopefully this should be the last rewrite
- The Python setup file now explicitly mentions more dependencies; this should
    assist with installation issues for PyPI, DEB and RPM packages
- The RPM package, which did not work at all on Tartube v2.0.016, is now
    working again

MINOR FIXES
- In the general download options window, in the Files tab, there was a
    duplicate set of template options. Remove the duplicate set, replacing it
    with a larger set of options
- Info/Tidy operations complained that they couldn't start while an edit/
    preference window is open, and then started anyway. Fixed
- In the Progress List, a video's name is updated as soon as it is known
    (before, the name was only updated in the Results List)
- The start of a download operation is now (slightly) quicker, because the
    setup code is no longer called (incorrectly) for every single video
- Download operations scheduled to begin when Tartube starts now begin after
    a few seconds, rather than immediately (for aesthetic reasons)

v2.0.016 (10 Apr 2020)
-------------------------------------------------------------------------------

MINOR NEW FEATURES
- Tartube's config file is stored in a standard location for your system, by
    default. For testing purposes, you can copy a config file into Tartube's
    installation directory (the one containing this file). If you do so,
    Tartube will load and later save that config file, rather than the one in
    the standard location
- Tartube no longer creates a youtube-dl archive file in its 'Unsorted Videos'
    and 'Temporary Videos' folders. Any existing archive files in those folders
    are automatically deleted. Other folders are not affected (Git #64)
- In the Videos tab, you can expand the tree on the left-hand side of the
    window by clicking on a folder (if this behaviour has been enabled). This
    behaviour has now been modified slightly. Clicking on a folder will also
    collapse the tree, if already expanded. You can tell Tartube to expand the
    whole tree, not just the folder itself. The settings can be specified by
    selecting the checkbuttons in Edit > System preferences > Windows >
    Main window

MINOR FIXES
- The system preferences window didn't show the correct location for the
    loaded config file. Fixed
- The DEB package has been improved to generate fewer Lintian error messages
- Tartube was unable to switch between databases, if the main 'Download all'
    button had been disabled. Fixed
- After deleting a folder, clicking the 'Add a new folder' button generated an
    error. Fixed
- If the internet connection goes down during a check operation, Tartube is
    now less likely to freeze
- The 'Apply changes without closing the window' button at the bottom of many
    edit windows did not work as intended. Fixed
- Video descriptions are no longer editable in a video's 'Video Properties'
    window

v2.0.0 (29 Feb 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Tartube can now be installed from PyPI, or by using the new DEB/RPM packages
    (Linux/BSD only; installation from PyPI does not work on MS Windows)
- DEB/RPM packages marked 'STRICT' are also available for uploads to
    repositories with lots of rules, such as the official Debian repository.
    In 'STRICT' packages, updating youtube-dl from within Tartube is disabled.
    The 'STRICT' packages are compiled using new environment variables,
    TARTUBE_PKG and TARTUBE_PKG_STRICT (replacing the old TARTUBE_DEBIAN)
    environment variable. See the comments in setup.py for more details
- During a download operation, in the Progress Tab, you can now right-click a
    video and select 'Stop after these videos'. This allows all of the current
    video downloads to finish, before halting the download operation
- The download options window (in the Formats tab) did not allow users to
    select an audio format before selecting a video format. The reason for this
    restriction was that youtube-dl did not download the right formats, if an
    audio format was selected first. Unfortuantely, it prevented users from
    downloading a separate audio file, when this was available (e.g. an .m4a
    file from YouTube). The restriction has now been removed; instead, Tartube
    will automatically reorder the specified video/audio formats, so that video
    formats are passed to youtube-dl first

MAJOR FIXES
- If an upload operation is automatically performed before a download
    operation, and if the user tried to download a single video/channel/
    playlist/folder, everything was downloaded instead of the single video/
    channel/playlist/folder. Fixed
- Fixed an error in the 'Show system command' dialogue window, that prevented
    it from opening at all
- Fixed parsing of download options inside double quotes "..."

MINOR NEW FEATURES
- Added a 'Cancel' button to some dialogue windows that didn't already have one
- Added a copy of the XDG module to the Tartube code, so it is no longer
    necessary to install it before running/installing Tartube (Linux/BSD only)

MINOR FIXES
- Fixed a system error during a forced youtube-dl update (MS Windows only)
- Fixed wrong location for config file backups (MS Windows only)
- Fixed wrong location for Tartube temporary/test folders (all systems)
- Fixed missing (or duplicate) dialogue windows after failing to load the
    config file and/or database file, in some rare situations
- The config file could not be created if its parent directory did not exist;
    fixed
- Fixed loading of the wrong database file, in some rare situations
- Removed the old 'hello world' code intended for testing on MS Windows; it's
    no longer required
- If Tartube can't find its icon files, a simple error message is now generated
    rather than a long traceback

v1.5.0 (22 Feb 2020)
-------------------------------------------------------------------------------

This is the first release candidate for v2.0.0.

MAJOR NEW FEATURES
- You can now run multiple instances of Tartube on your system at the same
    time. Multiple instances cannot load the same Tartube database; they must
    each load their own database. Tartube will now remember the databases it
    has loaded. If there are three databases (perhaps one on your main hard
    disk and two on an external drive), you can start Tartube three times, and
    they will each load a different database. This behaviour can be configured,
    if necessary. Click 'Edit > System preferences... > Filesystem > Database'
- HookTube acts as a redirection service for YouTube. Because of lawyers and
    their evil machinations, HookTube's functionality is not as extensive as it
    once was. Added the Invidious website (https://invidio.us/) as an
    alternative
- Added custom downloads. To start a custom download, click 'Operations >
    Custom download all', or right-click a video/channel/playlist/folder. A
    custom download is just like a normal download, until you customise it. To
    do that, click 'Edit > System preferences > Operations > Custom'. Custom
    downloads can be used to divert YouTube requests to HookTube or Invidious,
    and to insert a delay between video downloads when the website is
    complaining about robots
- Added a new toolbar at the bottom of the main window, below the list of
    videos. The toolbar is hidden, by default. To reveal it, click the 'Show
    filter options' button in the bottom right-hand corner. Buttons in the new
    toolbar can be used to sort the videos alphabetically, rather than by date,
    and to search for videos whose name matches a string (or regex). The button
    to search for videos by date has been moved into this toolbar
- If you find a video that can't be downloaded, and you're not sure why, you
    can now perform a test download. First, click 'Operations >  Test
    youtube-dl...' (or right-click a video in the main window's list). Copy the
    video's URL into the dialogue window, and then click the OK button. Click
    the Output Tab to see the results. If the test successfully downloads the
    video, then the problem was with Tartube. If the test fails to download the
    video, then the problem is with the underlying youtube-dl software (or with
    the video website)
- During a test, it's possible to omit the video URL, while specifying some
    youtube-dl download options. For example, you could fetch the youtube-dl
    version number with the option --version
- Added a new operation for tidying up files in Tartube's data directory
    (folder). To start the operation, click 'Operations > Tidy up files...'.
    You could also right-click a channel and select 'Channel actions > Tidy up
    channel', and so on. A dialogue window appears, in which you can specify
    which files should be tidied up. Choose carefully, because any files
    deleted as a result of this operation cannot be recovered
- The main window's switch button (in the toolbar near the top of the window)
    now has six settings, rather than four. Click the button repeatedly to
    cycle through them
- Interesting and important videos can now be bookmarked (e.g., by right-
    clicking a video and selecting 'Mark video > Video is bookmarked').
    Bookmarked videos are visible in the new 'Bookmarks' folder. Bookmarking is
    an alternative to favourites; bookmarks usually apply to a single video,
    whereas favourites usually apply to a whole channel, playlist or folder
- Also added a new 'Waiting Videos' folder. This acts as your own private
    playlist - a list of videos that are waiting to be watched. To make a video
    visible in this folder, right-click it and select 'Mark video > Video is in
    waiting list'. When you watch the video, it will automatically disappear
    from the 'Waiting Videos' folder (this doesn't happen to bookmarked videos)
- The previous version was unable to delete a channel, playlist or folder (see
    below). That error caused a partially-deleted channel/playlist/folder to
    appear in the Videos Tab, on the left-hand side. In case similar errors
    occur in the future, a feature has been added to look for errors and
    inconsistencies in the Tartube database and automatically fix them. Click
    'Edit > System preferences... > Filesystem > DB Errors > Check' to use it
- Tartube can now fetch a list of available video formats for a video. Right-
    click the video and select 'Fetch > Available formats'. Click the Output
    Tab to see the results
- Tartube can also fetch a list of available subtitles for a video. Right-click
    the video and select 'Fecth > Available subtitles'. Click the Output Tab to
    see the results
- Tartube can now remember the size of its main window, and use the same size
    when it restarts. This feature is disabled by default. To enable it, click
    'Edit > System preferences... > Windows > Main window > Remember the size
    of the main window when shutting down'

MAJOR FIXES
- In the previous version, Tartube was unable to delete a channel, playlist or
    folder. Fixed
- Some procedures took an extremely long time. For example, after right-
    clicking a channel and selecting 'Channel contents > Mark videos as new',
    the procedure could take several minutes if the channel had hundreds of
    videos, or several hours if it contained thousands of videos. The faulty
    code has been fixed, and the procedure now takes just a few seconds, even
    for many thousands of videos
- Videos in a Tartube folder (for example the 'Unsorted Videos' folder) were
    added to the download list in a 'Check all' operation, even when they had
    been checked before. This no longer happens, by default. To restore the
    original behaviour, click 'Edit > System preferences... > Operations >
    Downloads > For simulate downloads, don't check a video in a folder more
    than once' to deselect it
- Fixed the button for finding videos by date, which was not working at all in
    the previous version
- Fixed an occasional 'signal is not defined' error when the user stops an
    operation (for example, a download operation)
- Various inconsistencies in the way alternative download destinations are
    handled have all been fixed. Download operations sometimes freezed
    indefinitely, because Tartube doesn't download two channels/playlists/
    folders with the same download destination at the same time. The code has
    been updated to prevent the freeze from ever happening again
- Fixed some more crashes caused by Gtk during a download operation

MINOR NEW FEATURES
- Videos downloaded into a temporary folder are deleted when Tartube restarts.
    After shutting down Tartube, users often like to copy these videos
    somewhere else on their hard drive. You can now ask Tartube to open the
    temporary directories (folders), before shutting down, which will remind
    you to do something with the videos. To enable this behaviour, click
    'Edit > System preferences... > Filesystem > Temporary folders'
- In the main window's list of videos, the date is now displayed as 'today' and
    'yesterday' when possible. This behaviour can be disabled in 'Edit > System
    preferences... > Windows > Main window'
- During refresh operations, a progress bar is now visible in the bottom-left
    corner of the window (just like the one visible during a download
    operation)
- When setting an alternative download destination for a channel/playlist/
    folder (for example, by right-clicking a channel and selecting 'Channel
    actions > Set download destination...'), the dialogue window has been
    updated to show the previously selected alternative at the top of the list.
    This should save a lot of time when setting the alternative download
    destination for many channels/playlists/folders
- The alternative download destination, if any, is now visible in the tooltips
    for the channel/playlist/folder
- Improved the appearance of the dialogue windows seen when Tartube runs for
    the first time
- Tweaked the appearance of the list of channels/playlists/folders in the
    main window, so that for items with long names, more text is visible

MINOR FIXES
- Fixed a 'No such file or directory' error seen during a download operation,
    if an external hard drive suddenly become disconnected (for example, if
    the cable falls out)
- Fixed rare problems in loading Tartube's config file
- After a download operation, the list in the top half of the progress tab
    often had one or two items in it, even when 'Hide active rows after they
    are finished' was selected. Fixed
- The length of lines of text, and spacing between lines, in various dialogue
    windows has been made uniform
- Improved the appearance of the main window by adding frames around everything
- Renamed some misnamed icon files. The old icon files were being used in the
    MS Windows installer, so fixed that too
- If the user performed two successive refresh operations, the second one
    halted after a couple of seconds. Fixed
- When videos are deleted from Tartube's database, any post-processing
    artefacts are now deleted with them
- Fixed a few incorrect regex-matching actions
- The user can specify that the main 'Download all' button should be
    desensitised, but the setting was not applied correctly after Tartube
    restarted. Fixed
- Removed a duplicate menu option in the Video Index popup menu
- Tartube channels, playlists and folders keep counts of the number of videos
    inside them, including the number of favourite videos, downloaded videos,
    and so on. The code was not working correctly, so the counts were not
    always accurate. This version updates the code and recalculates all of the
    counts
- Fixed folder icons with an incorrect colour in various edit windows
- Fixed markup errors for videos whose URL contained an ampersand character
- Fixed the Gtk warning when closing the 'Add new video(s)' dialogue window
- Updated the installer scripts for MS Windows, so they don't try to update the
    Windows registry (the code has never worked)
- You can no longer set videos as favourite, or new (etc), in an empty channel,
    playlist or folder
- In the video list, labels can be right-clicked to copy a video's location
    (for example, so it can be copy-pasted somewhere else). This did not work
    the same way for every clickable label, and in some cases did not work at
    all. Fixed
- Tooltips for videos contained &amp; rather than a simple ampersand character.
    Fixed
- Tartube debug messages for the mainapp.py file (which can only be enabled
    by editing the file) now have a second debug flag, so the timer functions
    can be filtered out
- Checked all keyboard shortcuts to remove duplicates

v1.4.0 (2 Feb 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- The structures of files and directories (folders) in Tartube's data
    directory (into which all videos are downloaded) has been changed in
    response to Git #28. Tartube will be able to recognise both structures
    forever, so there is no need to move anything around on your computer. (If
    you actually want to move things around, see the README file)
- Creating a channel/playlist/folder starting with a full stop (period) is no
    longer allowed; some channels/playlists/folders might be automatically
    renamed when you open Tartube
- The edit and preference windows have been reorganised, adding a second
    layer of tabs in many windows. This should hopefully make things a little
    easier to find
- In the download options window, you can now specify multiple languages for
    your subtitles, instead of just one (Git #47)
- Added some more filename formats (in Edit > General download options...
    > Files > File names). When downloading a partial playlist (for example,
    starting at the 5th video), youtube-dl cannot create files with the correct
    number (naming the first file downloaded #1, instead of #5). Tartube can
    now handle this correctly. In the drop-down box, use one of the formats
    containing 'Autonumber' (Git #47)
- You can now limit the length of a download operation. This is particularly
    useful on small devices, or when leaving Tartube to run overnight. Click
    Edit > System preferences... > Scheduling > Stop, and choose one or more of
    the new options (Git #47)
- When adding new videos, channels or playlists, you can now turn on clipboard
    monitoring. Simply select a URL (for example, in your web browser), press
    CTRL+C to copy it to your system's clipboard, and then Tartube will
    automatically paste it into the dialogue window (Git #52)
- The MS Windows installer now includes a copy of AtomicParsley, so there is no
    need to install it yourself. This does not affect Linux/BSD users, who can
    continue installing AtomicParsley by the usual methods
- The list in the top half of the Progress Tab is often full, and it's
    sometimes difficult to see what is being downloaded right at this moment.
    You can now hide finished rows, if you want to, so that active rows appear
    at the top of the list

MAJOR FIXES
- The Gtk graphics libraries have historically been full of bugs, which made
    applications using Gtk unstable. Most of these bugs are fixed, but the
    fixes can take years before they propogate into operating systems. If Gtk
    v3.22 (or lower) is installed on your system, Tartube automatically
    disables some minor cosmetic features to prevent crashes. If you are using
    Gtk v3.24 or later, and are still experiencing unexplainable crashes, you
    can now disable the cosmetic features regardless of Gtk version. Click
    Edit > System preferences... > General > Modules, and select 'Assume that
    Gtk is broken...'
- On Linux/BSD, attempts to update youtube-dl from the Tartube menu so,etimes
    produced a 'permission denied' error. There are now new settings available
    in 'Edit > System prefences... > youtube-dl > Shell command for update
    operations'. If you installed youtube-dl using pip/pip3, the 'recommended'
    options should now work, if they didn't work before. Some pip3 warning
    messages, which caused Tartube to think the update had failed, are now
    filtered out
- A user complained that his Tartube database file had been corrupted. We are
    still not sure what the cause was, but the code has been changed to make
    that kind of corruption impossible
- Fixed some occasional crashes when, during a download operation, Tartube
    tried to sort the videos in the selected channel/playlist/folder
- When switching databases, if Tartube couldn't load the new database, it tried
    again after being restarted, rather than trying to load the previous
    (readable) database. This has now been fixed
- Some youtube-dl download options could be applied to playlists, but not
    channels, even though youtube-dl allows them to be applied to be both.
    Fixed, and updated some labels to make it clearer what the options are for
    (Git #47)
- In all edit windows, the 'Apply' button at the bottom of the window did not
    work. Fixed

MINOR NEW FEATURES
- Tartube icons have been updated, in some cases making them easier to identify
- In the Progress Tab, added tooltips to assist with identifying undownloaded
    videos (Git #51)
- More types of YouTube error message can now be filtered out
- We have also added a customisable list of strings (or regular expressions);
    if set, any matching error/warning messages (on any website) are filtered
    out
- In the Video Index popup menus, 'rename default location' has been changed
    to a much more comprehensible 'rename channel', etc
- You can now open a video in its system directory (folder) by right-clicking
    it, and selecting 'Show location'
- You can now switch databases from the main menu. Click File > Change database
    (which opens the preference window at the correct page; hopefully this is
    quicker than trying to find the right page yourself)
- There was no way to save Tartube's config file (except by shutting down
    Tartube). To do that, you can now click File > Save all
- If Tartube is unable to read the config file and/or database file, the text
    in the resulting dialogue windows has been improved. In some circumstances,
    multiple dialogue windows were produced; this has now been fixed
- In the download options window, the option to 'embed subtitles with video'
    now appears in two different places, to make it easier to find (Git #47)
- If the 'Add new video(s)', 'Add a new channel' or 'Add a new playlist'
    dialogue windows are open, you can now drag-and-drop into them (Linux/BSD
    only). Modifications to the code mean that it's no longer possible to
    drop one URL into the middle of an existing one, rendering both of them
    useless
- Tartube checked URLs for validity before adding them, but this did not work
    as well as intended. The code has been improved, so less garbage should
    appear in the 'Add new video(s)' dialogue window, and so on
- You could already download a temporary copy of video(s) by right-clicking
    them and selecting 'Temporary > Download', but that can be inconvenient
    for multiple videos, as you had to wait for each download to finish. You
    can now select 'Temporary > Mark for download' instead, which creates a
    copy of the video in the 'Temporary Videos' folder. When you're ready to
    download them all, just download that folder
- Minor improvements to aesthetics for some textviews and treeviews

MINOR FIXES
- Fixed incorrect operation of the checkbuttons in the Errors/Warnings Tab.
    Added new checkbuttons to separate Tartube errors/warnings from youtube-dl
    errors/warnings (Git #50)
- 'Child process exited with non-zero code' errors still appeared in the
    Errors/Warnins tab, even if the user has disabled them. Fixed
- Tooltips for videos could not be enabled/disabled if no channel/playlist/
    folder was selected. Fixed
- On MS Windows, edit/preference windows will no longer increase in size, if
    there isn't enough room for each window's tabs
- Fixed rare 'Permission denied' errors when trying to create a directory
    (folder) on the filesystem
- In the download options edit window, the combobox for audio formats had
    multiple and ever-increasing empty spaces. Fixed
- In the download options window, File > File names, the default value for the
    custom format was garbled. Fixed, and it should now be working as intended
- During a simulated download, videos which are not in a channel or playlist
    (for example, videos in the 'Unsorted Videos' folder) did not appear in
    the Results List in the Progress Tab. Fixed
- Fixed an unprintable character in the licence declaration, visible in
    Tartube's 'About' window
- When deleting a video, Tartube will now delete more related files (such as
    those produced when post-processing a video)
- Removed a few duplicate ISO 639-1 language codes

v1.3.077 (26 Jan 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Drag and drop (for example, from a web browser into Tartube's main window)
    is now fully working on Linux/BSD. On MS Windows, drag and drop does not
    work at all for any Gtk application. It is unlikely that the Tartube
    authors can do anything about this (Git #35)
- The 'Add new video(s)' dialogue window can now handle URLs representing
    channels and playlists, as well as URLs representing individual videos.
    During a download operation, if Tartube is expecting an individual video
    but receives a channel/playlist, it will automatically create a new
    channel, and download videos into that channel. You can change this default
    behaviour, if you want (Edit > System preferences... > URL flexibility
    preferences)
- To change the name of the new channel/playlist, right-click it and select
    'Filesystem > Rename default location...'
- If Tartube creates a channel, which should really be a playlist, then you
    can now convert one to the other. Right-click a channel and select
    'Channel actions > Convert to playlist'. Right-click a playlist and select
    'Playlist actions > Convert to channel'
- In the download options windows, it's now very easy to tell Tartube to
    convert videos to sound files. Open the window by clicking 'Edit >
    General download options...', click the 'Hide advanced download options'
    button if necessary, click the 'Sound only' tab, select your preferences,
    and apply them by clicking the OK button at the bottom of the window
- You can now see the download options applied to a video, channel, playlist
    or folder without having to download anything. Right-click a video/channel/
    playlist/folder and select 'Downloads > Show system command'
- During a download operation, the system commands used are now visible (by
    default) in the Output Tab. The system command can also be displayed in the
    terminal, if required; this is disabled by default

MINOR NEW FEATURES
- In the Output Tab, the summary page is now hidden by default. To make it
    visible, click 'Edit > System Preferences... > Output >
    Show a summary of active threads' and then restart Tartube
- In the Errors/Warnings Tab, added checkbuttons to filter out errors and/or
    warning messages, if required (Git #50)
- In the Progress tab, in the top half of the window, you can now right-click
    an unnamed video to open it in your web browser. This will be useful in
    identifying videos that did not download, and whose name is unknown to
    Tartube (Git #51)
- Columns in the Progress tab have been rearranged a little, so that the
    user can more easily see how quickly the download is progressing, when
    Tartube's main window is small

MAJOR FIXES
- Fixed multiple issues with Tartube, when running under Python 3.8
- Replaced all remaining references to the Python os.rename() function, which
    can cause crashes on some filesystems (Git #34)
- Fixed crashes caused by the new YouTube error messages (January 2020), which
    some versions of youtube-dl cannot handle correctly
- Fixed issues with the default location for videos, again. Fixed an issue
    with adding folders inside the currently selected folder (Git #36, #46)

MINOR FIXES
- Fixed various Gtk warning messages, visible only on some systems
- Videos whose name contains an ampersand (&) character could not be opened by
    clicking the 'Media player' label in the Video Catalogue. Fixed
- The properties windows for videos, channels and playlists showed a folder
    icon, instead of a video/channel/playlist icon. Fixed
- The popup menu in the Progress tab, in the top half of the tab, did not work
    as intended during a download operation, and again after a download
    operation. Fixed both sets of issues
- Coloured text was not displayed in the Output Tab correctly. Fixed

v1.3.048 (23 Jan 2020)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Tartube now creates an icon in the user's system tray. Closing the main
    window now closes to the tray, by default. To disable this behaviour,
    click Edit > System preferences > Windows > Deselect 'Close to the tray...'
- When that functionality is enabled, Tartube can be shutdown by clicking
    File > Quit. Scheduled download operations will still take place if Tartube
    has been closed to the tray. Implements Github issue #37
- Tartube can now show a desktop notification at the end of a download
    operation, rather that a dialogue window. This does not work on MS Windows.
    On other operating systems, enable desktop notifications by clicking
    Edit > System preferences... > Operations > Show a desktop notification...
- When you click the 'Add new video(s)' button, the folder displayed in the
    dialogue window is now the same folder that's selected in the main window
    (if any). The same applies for adding channels, playlists and folders.
    Fixes Github issue #36
- If you normally use the 'Check all' button rather than the 'Download all'
    button, and if you want to download a temporary copy of one of the videos,
    there's now an easier way to do it. In the Videos tab, right-click the
    video, and select 'Temporary > Download' or 'Temporary > Download and
    Watch'. A copy of the video is downloaded into the 'Temporary Videos'
    folder, without affecting any other folders

MINOR NEW FEATURES
- The icons for channels and playlists have been replaced, to make it easier to
    tell them apart. Some other icons have been replaced too
- Videos can now be dragged and dropped from a web browser (or similar
    application) into Tartube's main window, which automatically adds the video
    to the currently selected folder (or 'Unsorted Videos', if no folder is
    selected). Unfortunately, the code is not yet working reliably. We are
    looking for a solution (Github issue #35)
- The layout of the Format tab in the download options window has been improved
    to alleviate confusion experienced by users trying to download a video to
    a sound format such as .mp3 (only). See the new section in the README file
- A number of new video/audio formats have been added, for example several new
    60fps formats, implementing Github issue #40
- When you apply download options to a video/channel/playlist/folder, the
    options are now cloned from the default set of options (those visible in
    Edit > General download options...). To disable this behaviour, click
    Edit > System preferences... > Operations > When applying download options,
    automatically clone general download options. Implements Github issue #39
- The options already applied to a video/channel/playlist/folder can now be
    reset to match the general options, any time you want. Use the new button
    at the bottom of the download options window, in the General tab

MAJOR FIXES
- Fixed a rare crash when the video's JSON filename was too long for the
    operating system
- In the download options window, Formats tab, the user can add up to three
    video formats. The third format, if added, was always ignored. Fixed

MINOR FIXES
- If you perform a refresh operation on a folder, the operation now applies to
    all videos, channels, playlists and folders inside it
- After adding a video to the folder that's currently selected, the video does
    not appear immediately in the video catalogue. Fixed
- In the Progress and Errors/Warnings tabs, the column headers scrolled away
    along with the rest of the list. Fixed; they are now always visible
- Video nicknames were not set correctly after an update operation. Fixed
- During a refresh operation, a video's name was compared against the full
    filepath (filename and extension), which produced none of the intended
    matches. Fixed
- The edit/preference windows had a tendency to increase in size without
    limits. Fixed
- A video's annotations.xml file was not deleted correctly, when required.
    Fixed
- In the download options window, the option 'hls-prefer-ffmpeg' is now working
    correctly
- In the download options window, the 'prefer avconv over ffmpeg' options have
    been desensitised on MS Windows, as there is no known method of using
    Tartube with avconv on MS Windows
- youtube-dl creates a file, ytdl-archive.txt, recording all the videos that
    it has downloaded. This can interfere if the user tries to re-download the
    video(s) for any reason. Create of the ytdl-archive.txt file can now be
    disabled (Edit > System preferences... > youtube-dl > Deselect 'Allow
    youtube-dl to create its own archive...')
- If creation of the archive file is nonetheless enabled, Tartube can now
    re-download video(s) without problems
- In rare circumstances, Tartube was unable to redraw the video catalogue
    (the right-hand side of the Videos tab). Fxied

v1.3.007 (20 Dec 2019)
-------------------------------------------------------------------------------

MAJOR FIXES
- v1.3.007 was completely broken when replacing an earlier installation. Fixed
- When Tartube's data directory was copied from one place to another (for
    example, from one external drive to another), Tartube did not adapt to the
    change very well. The way file paths are stored in Tartube's database has
    been changed to eliminate this problem

MINOR FIXES
- Fixed an invalid time value which (sometimes) prevented a refresh operation
    from completing correctly

v1.3.0 (20 Dec 2019)
-------------------------------------------------------------------------------
MAJOR NEW FEATURES
- Tartube on MS Windows did not recognise FFmpeg or AVConv. You can now tell
    Tartube to download and install a compatible version of FFmpeg from the
    main menu (Operations > Install FFmpeg). Tartube still cannot recognise
    the ordinary version of FFmpeg, and it still does not recognise AVConv at
    all. It is unlikely that this situation can be remedied
- A new Output Tab has been added, in which you can see what is happening
    internally when you check or download videos, update youtube-dl, install
    FFmpeg, or refresh the Tartube database. The amount of information shown
    can be customised in the System preferences window. The information can
    still be written to STDOUT/STDERR, if required
- For users on other operating systems, the system preferences window
    displayed the wrong location of the FFmpeg/AVConv executable. This has now
    been fixed
- There are now two simple ways to specify the video resolution you want to
    download (for example, 1080p). You can use the download options window
    (Edit > General download options... > Formats, and then choose a video
    format like 'any format [1080p]'). You can also use the new spinbutton at
    the bottom of the Progress Tab. Both of these methods have the same effect,
    so it's not necessary to use both of them. Tartube will download videos in
    that resolution if possible, or in the next highest available resolution
    otherwise
- The download options window has been simplified, with only the most useful
    options visible. If you want to see the full range of options, open any
    download options window, and in the General tab, click the new 'Show
    advanced download options' button

MINOR NEW FEATURES
- By default, temporary folders are no longer emptied when Tartube shuts down,
    but only when Tartube starts up. This means you can continue watching
    temporary videos you've downloaded even after shutting down Tartube. If you
    want temporary folders to be emptied on shutdown, as before, select Edit >
    System preferences... > Videos > Empty temporary folders when Tartube shuts
    down

MAJOR FIXES
- Tartube experienced a whole range of problems when downloading videos to a
    hard drive that was running out of space. Tartube now checks the available
    disk space before starting to download anything, and continues checking it
    throughout the download process. You can specify how much disk space should
    be available in the System Preferences window. If the hard drive, despite
    your best efforts, actually does run out of space, Tartube is now much more
    resilient (and can usually halt the download process, rather than
    crashing). The amount of disk space available is now visible in the System
    Preferences window
- Adding a channel/playlist/folder whose name included a slash, for example
    'Adam/Eve's Channel', had unfortunate consequences, with Tartube creating
    a directory (folder) at the wrong location. Slashes are now automatically
    converted to hyphens, which solves the problem
- In Tartube's window, dragging a channel/playlist/folder to a new location in
    the tree changes the hard drive, moving a directory (folder) to a new
    location in the filesystem. If a directory (folder) with the same name
    already existed at that location, an invisible error occurs. Tartube now
    displays a visible error so the user can delete the duplicate directory
    (folder) manually
- When refreshing the Tartube database (e.g. Operations > Refresh database),
    the moviepy module freezes if it encounters a corrupted video file. We
    can't fix the moviepy module, but the Tartube code has been made much more
    resilient
- When refreshing the Tartube database, Tartube made bad decisions if it was
    looking for a video called 'ymca.mp4', but found a video called
    'ymca.webm'. This has been fixed
- Tartube is now able to detect if its data directory (into which videos are
    downloaded) doesn't exist. Usually this is because an external hard drive
    has not been mounted; the user is now warned about this, so they can mount
    it
- On MS Windows, if the user has updated youtube-dl or installed FFmpeg,
    Tartube no longer freezes on shutdown
- On MS Windows, Tartube was unable to open a video file in the system's
    default media player, if the name contained an ampersand. Fixed

MINOR FIXES
- When deleting large channels/playlists/folders, sometimes not everything was
    deleted, and the user had to delete the item a second time. This was due to
    inconsistencies in the Tartube database, which have now been fixed
- Channels/playlists/folders beginning with a number, e.g. '5 Pewdiepie', were
    supposed to be displayed in numerical order, rather than in strict
    alphabetical order. This did not work as intended (e.g. '11 Pewdiepie' was
    listed before '1 T-Series'). Fixed again
- In the 'Delete channel' dialogue window (and so on), the name of the channel
    to be deleted is now displayed prominently
- The size of the MS Windows installer has been reduced by about 40%

v1.2.008 (30 Sep 2019)
-------------------------------------------------------------------------------

MINOR NEW FEATURES
- Tartube now ignores the YouTube 'WARNING: video doesn't have subtitles'
    by default. You can change this setting, if you want to

MAJOR FIXES
- When moving a channel/playlist/folder to a different place on your
    filesystem, or when renaming a channel/playlist/folder, in certain rare
    situations data in the Tartube database isn't updated correctly. This may
    lead to a freeze or a crash. I'm not sure yet what the cause is, but I have
    added temporary code to prevent the problem affecting any user
- Fixed error messages generated when checking/downloading individual
    channels/playlists/folders
- Fixed faulty code for importing videos/channels/playlists/folders into the
    database

v1.2.0 (31 Aug 2019)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- Multiple channels, playlists and/or folders can now download their videos to
    a single location. The README.rst file explains how it works, and why you
    might want to do it
- You can also tell Tartube to download all videos into the 'Unsorted Videos'
    or 'Temporary Videos' folders, instead of downloading them into separate
    directories/folders for each channel and playlist
- Added automatic deletion of videos, disabled by default. Before enabling it,
    you should do a 'Check all' or 'Download all' operation, which will create
    the necessary youtube-dl archive files
- Added archiving. A video, channel, playlist or folder that is marked
    archived won't be auto-deleted (but can still be deleted manually by the
    user)
- You can now disable both checking and downloading a channel, playlist or
    folder, if you want to. (It was already possible to just disabled
    downloading them)
- Download operations can now be scheduled to take place at regular intervals
- You can now 'Download and watch' a video. The video is opened in your
    system's default media player as soon as it has been downloaded
- Tartube can now download a video's annotations file automatically. Warnings
    generated by YouTube about the lack of annotations are ignored by default
- For channels/playlists/folders containing many videos, you can now skip to
    the first video uploaded after a certain date, using the new button in the
    toolbar at the bottom of the Videos Tab
- The lists in the Results Tab can now be right-clicked, so you can change the
    order in which videos/channels/playlists/folders are checked/downloaded,
    abandon a download, play a video directly from the Results List, delete a
    video directly from the Results List, and so on
- The edit window for youtube-dl options has been improved, adding many new
    options to the GUI interface
- Plain text exports of Tartube's database can now be re-imported. Some
    inconsistencies with the import process (from JSON and plain text files)
    have been fixed

MINOR NEW FEATURES
- Added tooltips in several places. If you don't want to see tooltips above
    videos/channels/playlists/folders, you can turn them off
- You can now select multiple videos in the Video Catalogue, and apply an
    action to all of them (by right-clicking them)
- You can now switch to smaller icons in the Video Index (on the left side of
    the Videos Tab), if you want to
- You can now force the Video Index to expand its tree whenever you click on a
    folder, revealing any channels/playlists it contains. This is disabled by
    default
- If you only want to check videos, and never download them, you can disable
    the 'Download all' buttons. Individual videos/channels/playlists/folders
    can still be downloaded by right-clicking them
- Tartube's file structure has changed. If you run it from the command line,
    you might need to use a (slightly) different command. See the README.rst
    for details of what command to use
- The path to the FFmpeg/AVConv executable can now be specified by the user.
    This will be especially helpful for MS Windows users
- Columns in the Progress Tab can now be manually resized
- The Tartube website can now be opened from the main window menu
- XDG has been added as an optional dependency, for the benefit of Debian
    packagers

MAJOR FIXES
- The MS Windows installer should now work for everyone
- Refresh operations are now stable (should not crash) on systems with Gtk 3.22
    or earlier
- When downloads were disabled for a folder, downloads for channels/playlists/
    folders inside that folder were still enabled. This is counter-intuitive,
    so disabling downloads for a folder disables downloads for everything it
    contains
- Marking/unmarking a video as favourite caused certain problems, which should
    now be fixed

MINOR FIXES
- Fixed some unicode errors in reading JSON and plain text files
- Fixed the wrong page size displayed in the toolbar at the bototm of the
    Videos Tab
- Empty lines in a video's description are now preserved when they're displayed
    in Tartube's main window

v1.1.0 (18 Aug 2019)
-------------------------------------------------------------------------------

MAJOR NEW FEATURES
- You can now create an export of Tartube's database. This export contains
    details of videos, channels, playlists and/or folders, but not the videos
    themselves (or any of the thumbnail/description/metadata files). The
    export can take two forms: JSON data, or plain text. If JSON data, the
    exported file can later be imported into another Tartube database (imports
    from plain text are not implemented yet). You can export either the
    entire database, or just one channel/playlist/folder (and everythng it
    contains)
- You can now change the name of a channel, playlist of folder. This doesn't
    have any effect on your filesystem; it only changes the name displayed in
    the Video Index (the left-hand side of the Videos Tab). This might be
    useful for channels and playlists that have weird or very short names. For
    example, right-click a folder and select 'Folder actions > Set nickname...'
- You can also rename the channel, playlist or folder, and this action DOES
    affect the filesystem, changing the directory/folder on your hard drive
    where the channel/playlist/folder videos are stored. For example, right-
    click a folder and select 'Filesystem > Rename location...'
- If you change the format of a downloaded video file from the default 'Title'
    to, for example, 'Title + ID', the Video catalogue (the right-hand side of
    the Videos Tab) will now simply display the video's title (which should be
    easier to read). To see the actual filename, you can right-click the video
    and select 'Show properties'. This only works if the video's metadata was
    downloaded when the video itself was downloaded; this is now turned on by
    default for all new users

MINOR NEW FEATURES
- When adding videos, channels and playlists, the contents of the system's
    clipboard was automatically copied into the window. This can now be turned
    off, if you wish (Edit > System preferences... > Windows > When adding
    videos/channels/playlists, copy URLs from the system clipboard)
- When adding channels/playlists, you can set the dialogue window to stay open,
    which makes adding multiple channels/playlists quicker (Edit >
    System preferences... > Windows > When adding channels/playlists, keep the
    dialogue window open)
- When creating channels/playlists/folders inside an existing parent folder, a
    dialogue window which stays open can be told to continuously re-use that
    parent folder (Edit > System preferences... > Windows > When adding
    channels/playlists, re-use the optional parent folder)
- When checking/downloading videos, the Results List (the bottom half of the
    Progress Tab) can now display videos in reverse order, so you don't have to
    scroll down to see the video that was just checked/downloaded (Edit >
    System Preferences... > Windows > Show results in reverse order)
- The number of ystem error and warning messages displayed in their own tab
    is visible in the tab's label. The label is usually reset when the tab
    is made visible. You can now disable this behaviour, preserving the numbers
    until the 'Clear the list' button is explicitly clicked (Edit >
    System preferences... > Windows > Don't remove number of system messages
    from tab label until 'Clear' button is clicked)
- Items in the Video Index (on the left-hand side of the Videos Tab) are sorted
    alphabetically. The sorting algorithm has been improved to take account of
    numbered items, such that '1 Music' will now appear before '11 Comedy'
- For the benefit of package maintainers (such as a Debian package), Tartube
    now uses an environment variable which will prevent Tartube from updating
    the youtube-dl binary, if specified. See the comments in setup.py

MAJOR FIXES
- Users whose system Gtk is earlier than v3.24 (this includes many current
    Linux distros, but the MS Windows installer) will have experienced graphics
    issues, and endless error messages in the terminal window, if open. If your
    system Gtk is earlier than v3.24, Tartube will no longer update the Video
    Index during a download operation; this should fix the issue at the cost of
    disabling real-time updates of the number of videos in each channel,
    playlist and folder. Your system's Gtk version is now visible in Tartube's
    System Preferences window
- After loading the config file, the download limits were set, but not
    displayed in the Progress Tab. Fixed
- Rarely, Tartube crashes (or freezes) when loading a video's JSON metadata
    file from your filesystem (but now when downloading it). This should no
    longer happen

MINOR FIXES
- The 'Channel properties', 'Folder properties' (etc) windows used the wrong
    icon (displaying a folder in the wrong colour). Fixed
- Fixed a 'list modified during sort' error during a download operation

v1.0.0 (31 Jul 2019)
-------------------------------------------------------------------------------

- First beta release
- Fixed some issues with the MS Windows installer
- Some parts of the Tartube window displayed the wrong icons. Fixed

v0.7.0 (7 Jul 2019)
-------------------------------------------------------------------------------

- This is the first release candidate for v1.0.0
- The MS Windows installer has been redesigned again (thanks to slartie for his
    generous assistance in getting it working). Some MS Windows 10 users were
    still complaining that Tartube would not run; this should be fixed now
- MS Windows should find that the annoying terminal window is no longer visible
- Deleting individual videos, then adding them to the Tartube database again,
    could cause problems with the statistics displayed in the Video Index (e.g.
    'All Videos (0, -1)'. Fixed
- Deleting and individual video by right-clicking it removed the video from the
    database, but didn't delete the video file itself. Fixed
- If an empty channel/playlist was selected, new videos did not automatically
    appear in the Video Catalogue during a download operation. Fixed
- Fixed some issues with the Temporary Videos folder
- Fixed more issues with videos being dislayed in the wrong order in the Video
    Catalogue
- Fixed more issues with the scrollbars not resetting themselves when switching
    between channels/playlists/folders
- After right-clicking a folder, selecting Mark Videos > New didn't work. Fixed
- When marking videos as new/favourite, you can now do this to all videos
    in a folder, including all child channels/playlists/folders, or you can do
    it just to the videos actually inside that folder. There are several new
    popup menu options for emptying a folder, or for removing all its videos
- Tartube will no longer issue a system error if you drag a folder onto itself
    in the Video Index
- Fixed the remaining issues caused by the Gtk graphics libraries
- Confirmed that various Gtk issues present in Gtk3.22 are not present in
    Gtk 3.24. Users with Gtk 3.22 on their system will be warned to update it.
    These warnings can be disabled, if required

v0.6.0 (4 Jul 2019)
-------------------------------------------------------------------------------

- Some MS Windows users, especially on Windows 10, report that they can't run
    Tartube at all. In an effort to get around this, the installer has been
    redesigned. The way Tartube communicates with youtube-dl on MS Windows has
    been changed. youtube-dl update operations should now work flawlessly.
    Please report any further problems at our GitHub page; this might be a fix
    to issue #10
- Users on Linux/*BSD can now run Tartube directly from the command line, after
    installing it (see the README)
- Occasionally, videos were downloaded (or checked) successfully, but Tartube
    failed to notice them. This issue should now be fixed
- When checking videos/channels/playlists/folders, only new videos will now
    appear in the Results List (in the 'Progress' Tab)
- The toolbar has been redesigned. MS Windows users won't see labels at all
    (so everything should fit). Users on all system can turn labels on or off.
    Tooltips have been added to the buttons, in case the labels are turned off
- Fixed yet another problem with button to switch the location of Tartube's
    data folder (#6)
- Tartube no longer requires the python 'validators' module
- Tartube can now ignore YouTube copyright messages, and also 'Child process
    exited with non-zero code' messages, meaning that they won't appear in
    Tartube's Errors/Warnings Tab. (They are not ignored by default)
- Tartube now applies a 60-second timeout when youtube-dl tries to download
    a video's metadata (since youtube-dl uses a 10-minute timeout); this can be
    turned off, if required (#9)
- Fixed some more issues with the way videos are sorted in the Video Catalogue
    (it's still not 100%)
- Users can no longer type in comboboxes
- Tartube now spots when the user adds a channel or playlist URL as a video;
    only the first video in the channel/playlist is now downloaded
- You can no longer remove download options from a media data object when the
    download options edit window is still open
- When you update youtube-dl, Tartube will now tell you which youtube-dl
    version is installed. Tartube will no longer claim the update operation
    fails if you're using pip (rather than pip3)

v0.5.0 (1 Jul 2019)
-------------------------------------------------------------------------------

- On MS Windows, the fix from v0.4.0 to prevent a crash whenever the user tries
    to change the location of Tartube's data directory, did not work. Fixed it
    again (#6), and added some dialogue window to make it clearer to the user
    what is going on
- Fixed problems with dragging-and-dropping (or otherwise moving) a channel,
    playlist or folder to a new location (such as another folder). The videos
    were not updated with their new location. The new code will fix any
    problems in the Tartube database
- Fixed numerous problems with the code that sorts videos into the right order,
    and which displays videos in the Video Catalogue in the right order
- The 'Switch' button no longer resets the page back to the first one
- When switching between channels/playlists/folders, scrollbars are
    automatically moved back to the top
- In the toolbar beneath the Video Catalogue, there are two new buttons for
    scrolling to the top or bottom of the visible page. Users can now select
    a different page just by typing the page number and pressing RETURN. The
    same applies to the page size - there is no button to click any more, just
    type the new size and press RETURN
- Fixed several problems which were still preventing selection of different
    video formats (#3)
- Added bare-bones aac, m4a, mp3, ogg and wav as recognised video formats
- A set of download options can now be completely reset to their default values
- The 'Add Videos' dialogue window, and some others, don't behave well when the
    user resizes them. Fixed (#4)
- Added a small folder icon to the the 'Add Videos' dialogue window, and
    others, so the user is less likely to forget to set a custom location
- In the 'Add Videos' dialogue window, and others, URLs are now tidied up a
    bit because being copied from the clipboard, eliminating leading/trailing
    whitespace and empty lines
- The Gtk test window, available for MS Windows after using the installer,
    now contains some text (to make it clear that the window is working as
    intended)

v0.4.0 (29 Jun 2019)
------------------------------------------------------------------------------

- Drastic improvements to overall performance. Download operations are now much
    smoother. You should notice a much lighter burden on your machine's CPU
- The graphics libraries struggled to draw lists containing hundreds (or
    thousands!) of videos, so the Video Catalogue has been split into pages. It
    typically takes less then a second to show the 'All Videos' folder, if it
    contains hundreds of videos, rather than several minutes
- If you just want to find new videos, you can now tell Tartube to stop
    checking/downloading channels/playlists as soon as notifications of videos
    you've already checked/downloaded start arriving. This works well on
    YouTube, which sends the newest videos first, but might not work well on
    all websites. The new functionality is turned off by default. Click
    'Edit > System preferences > Performance > Time-saving preferences' to turn
    it on
- The installer for 32-bit MS Windows failed under all circumstances. Applied a
    fix
- On MS Windows, the uninstaller was invisible. It can now be executed from the
    Start Menu
- On MS Windows, fixed a crash whenever the user tried to changed the location
    of Tartube's data directory (#6)
- Fixed some problems with the 'Add videos' dialogue window, which tried to add
    all sorts of invalid URLs (such as lines containing only empty space). The
    other 'Add' dialogue windows were also fixed
- A limit to the length of a channel/playlist/folder name now applies
- Leading/trailing whitespace is now removed from URLs and channel/playlist/
    folder names
- The 'Add videos' dialogue window now checks for duplicate URLs, and when
    found, doesn't add them to the database
- Fixed various problems caused by deleting a video/channel/playlist/folder
    (such as the numbers visible in the Video Index). If you've been using an
    earlier version of Tartube, any such problems with the database will be
    automatically repaired for you (#8)
- Videos which haven't actually been downloaded can now be deleted from the
    database by right-clicking them
- Added new options for making backups of the Tartube database file, in case it
    becomes corrupted. See the settings in
    'Edit > System preferences... > Backups'
- The 'Switch' button now switches between four 'skins' (instead of the
    previous two). Two of them show the name of a video's parent channel/
    playlist/folder; the other two show the video's description
- Fixed incorrect formatting in the DASH and 3D file formats (#3)

v0.3.0 (25 Jun 2019)
-------------------------------------------------------------------------------

- Tartube will now run on MS Windows
- Fixed some more crashes
- Fixed some issues with video descriptions containing quotes and ampersand
    characters

v0.2.0 (23 Jun 2019)
-------------------------------------------------------------------------------

- Corrected old Python2 code to work on Python3
- Greatly expanded the README file
- Fixed the constant crashes
- Fixed some Gtk problems (but others remain unfixed)
- Fixed downloads for users who haven't installed Ffmpeg, and for sites that
    don't support Ffmpeg
- Several other minor tweaks/fixes

v0.1.0 (27 May 2019)
-------------------------------------------------------------------------------

- This is the first public release of Tartube
