As of December 23, 2020, OTRS AG released a security advisory declaring that OTRS 6, including ((OTRS)) Community Edition 6 (the version run on ticket.wikimedia.org), is end of life. No further security updates will be provided.
Previous statements from OTRS AG implied that ((OTRS)) Community Edition 7 would be released when OTRS 8 was released, but this has not happened. OTRS AG has also archived https://github.com/OTRS/otrs and most of their other public GPL repos.
Potential solutions:
- Pay for non-free OTRS 7/8
- Use an OTRS fork instead
- Drop OTRS entirely for different software
