As every so often, usually a few weeks, Project Debian has released new installation images of its operating system. The previous one was 11.4, and yesterday, also on Saturday, threw Debian 11.5. This is the fifth maintenance update for Bullseye, and it includes the latest security patches, updated packages, and bug fixes. Project Debian reminds with each of these releases that this is not a completely new version of the operating system, so existing users should not consider doing a fresh install.
Debian 11.5 includes 53 security patches, and a total of 58 bugs fixed in a bit of everything. Combined, they make 111 corrections, to which should be added those of the programs themselves, which have also been updated in the last two months with new functions and their own security and maintenance patches.
