Preliminary support for Joomla 6. This version comes with preliminary compatibility with Joomla! 6. At the time of this writing, Joomla 6.0 Alpha 2 has just been released, and that's our compatibility target. We expect more changes to take place before Joomla! 6 stable is released, with as yet unknown impact to compatibility. We will keep following Joomla 6 development and adapting our software as necessary.
No longer report Joomla API application's NotAcceptable exception by email. This is an expected exception, exactly like the 403 Forbidden and 404 Not Found errors you see in the Joomla frontend application. It makes no sense to report it as an error (when it's actually not!), confusing the user.
Bug fixes and minor improvements.
