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

- Implemented a way to feed CVE descriptions into the security tracker
  that relies on the MITRE API, as the NVD feeds are discontinued. This
  also helps the ELTS security tracker. Tested and deployed the change.

- Updated tzdata for the leap-seconds file.

I also worked on the following tasks for ELTS:

- Switched to dput-ng for upcoming changes in the infrastructure, and fought
  sftp to make it work on my system with the freexian server. Thanks Helmut
  for the assitance in debugging the issue.

- Updated tzdata.
