For developers: what the fix changed

The fix updates `RestAPI::applies()` in `src/Authentication/Provider/RestAPI.php` and `DisallowAPIRequests::check()` in `src/PageCache/DisallowAPIRequests.php` to use `$request->getPathInfo()` instead of `$request->getRequestUri()` for path matching. It also replaces a literal string check for `?_format=` with `$request->query->has('_format')` to prevent attackers from bypassing authentication by reordering query parameters.

Also in this release The release also added GitLab CI configuration and a new functional test.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK charities, membership bodies and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
