During the month of March, I worked on the following tasks for LTS:

- Worked on backporting a new version of tzdata. For a while we have been
  backporting specific cherry-picks instead of backporting the full upstream
  releases. This was due to upstream changes that caused incompatibilities with
  our tzgen from libc and the way we built the package. We want to change that
  and backport the full upstream releases again to ease maintainability in the
  long term, and I have been looking at the required changes to the build
  process to make it happen.

- Prepared various security updates (firefox-esr, thunderbird).

- Looked at a security-tracker issue where unimportant issues were shown as
  vulnerable. However the change has been reverted for now as it was causing
  other issues to be marked as unimportant, apparently due to issues with the
  DB status. Will have to take another look at that.

I also worked on the following tasks for ELTS:

- Backported linux-5.10.
