For developers: what the fix changed

The fix replaces the generic 'access content' permission on the block API route with a custom access check in `BlockApi::access()` that verifies the requester is a known device or has preview permission. It also updates `BlockApi::request()` to verify that the requested block is a valid signage block using the new `isSignageBlock()` method, returning a 404 if it is not.

Also in this release The release introduces a `Regions` class to centralise region names and adds comprehensive tests for the block API route.

Get in touch

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

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.
