For developers: what the fix changed

The fix replaces a hardcoded default encryption key with a site-specific key generated using `random_bytes()` and stored in the site's state storage. This is implemented by introducing a new `StateKeyProvider` in `src/Plugin/KeyProvider/StateKeyProvider.php` and updating the installation and update hooks in `cms_content_sync.install` to generate and use this new key.

Also in this release The release also updates the changelog.

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 membership bodies, charities 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.
