Contributions from outside the LTS Team:
- As usual, the thunderbird updates, released as DLA 4534-1 and DLA 4549-1, were prepared by its maintainer Christoph Goehre. This month 28 CVEs has been fixed. Thanks a lot for his continuous contributions. The DLAs have been sent by Emilio.
- Thanks alot as well to Mathias Behrle for providing DLA 4543-1 for package simpleeval. The DLA has been sent by Santiago.
The LTS Team has also contributed with updates to the latest Debian releases:
- Andreas Henriksson completed the upload of gvfs for trixie and bookworm
- Ben Hutchings did uploads of several kernel packages to unstable and the corresponding backports repositories.
- Sylvain took care of uploads of awstats to trixie and bookworm. He also did the same for 7zip-rar with an upload to bookworm-backports).
Some milestones in the lifecycle of two Debian releases are just around the corner. The support of Debian 12 will be handed over to the LTS team on June 11th 2026. After August 31st, support for Debian 11 will move from Debian LTS to ELTS managed by Freexian.
