For developers: what the fix changed

This release carries 2 security fixes. The summary below is for SA-CONTRIB-2026-057, the most serious of them.

The fix clones the context definition in `AiAgentEntityWrapper::setToolUsageLimits` to prevent mutating the shared cached definition across agent instances, which stops parameters from being inherited. It also adds field-level access checks to `ContentEntitySeeder`, `GetCurrentContentEntityValues`, and `ListContentEntities` to ensure users have the appropriate view or edit permissions.

Also in this release The release also updates regex constraints to use named arguments, changes token replacement to not escape HTML markup, adds a logger channel, and removes some tests.

1.1.3 to 1.1.4 5 commits, 13 files including 3 tests.

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.
