For developers: what the fix changed

The fix modifies `JsonController::json` to query and load entities using the entity storage with access checks (`$storage->getQuery()->accessCheck(TRUE)` and `$entity->access('view')`), rather than querying the database table directly.

Also in this release Added an export file name option for the data field table formatter, implemented plugin caching for performance improvements, and fixed minor typos.

2.0.12 to 2.0.13 3 commits, 9 files including 1 test.

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.
