kurnosem It's still active - you'll see KevinTheJedi, one of the developers, posting here quite frequently. Currently the main focus is on osTicket v2, which is a complete rewrite of everything, so only security updates will be worked on for the current version.
Personally I'm hoping an update comes along with official support for PHP 8.3 soon given 8.2 goes end of support at the end of this year, but I'm not sure on the exact plan - just know that the project is still active!
