|

- Support for CUDA 10 has been dropped, as announced in the 24.11 release notes.
|
||||
|
||||
- `zammad` has had its support for MySQL removed, since it was never working correctly and is now deprecated upstream. Check the [migration guide](https://docs.zammad.org/en/latest/appendix/migrate-to-postgresql.html) for how to convert your database to PostgreSQL.
|
||||
|
||||
- `kanata` was updated to v1.7.0, which introduces several breaking changes.
|
||||
See the release notes of
|
||||
[v1.7.0](https://github.com/jtroo/kanata/releases/tag/v1.7.0)
