The big ticket feature in this release is [CEL expression matching support](https://anubis.techaro.lol/docs/admin/configuration/expressions). This allows you to tailor your approach for the individual services you are protecting.

These can be as simple as:

```yaml
- name: allow-api-requests
  action: ALLOW
  expression:
    all:
      - '"Accept" in headers'
      - 'headers["Accept"] == "application/json"'
      - 'path.startsWith("/api/")'
```

Or as complicated as:

```yaml
- name: allow-git-clients
  action: ALLOW
  expression:
    all:
      - >-
        (
          userAgent.startsWith("git/") ||
          userAgent.contains("libgit") ||
          userAgent.startsWith("go-git") ||
          userAgent.startsWith("JGit/") ||
          userAgent.startsWith("JGit-")
        )
      - '"Git-Protocol" in headers'
      - headers["Git-Protocol"] == "version=2"
```

The docs have more information, but here's a tl;dr of the variables you have access to in expressions:

This will be made more elaborate in the future. Give me time. This is a [simple, lovable, and complete](https://longform.asmartbear.com/slc/) implementation of this feature so that administrators can get hacking ASAP.
