Improve user invitations to tickets. Invited users can now choose to leave a ticket after accepting the invitation. Managers can see which users are invited, and remove an invited user.
Improved error messages when a non-existent ticket ID is accessed in the frontend. You now get the correct 404 Not Found response instead of a server error or access forbidden response.
Support for indexing custom fields in Smart Search. Joomla 5.3 has support for searching by custom fields using its Smart Search component. Custom fields in ATS are now fully supported for use with this feature.
