New package! KeepassXC 2.6.0 (the latest stable). This is built from Debian's sources, they simply didn't have it pushed to buster-backports yet and I got tired of waiting. I'm using it myself with no issue, but backup your databases just-in-case!
The deb, repository, and git commit are signed with my keys.
Also, some basic updates:
Updated Librewolf to 79.0 and telegram-desktop to 2.2.0.
