Debian has major release versions. The Debian stable version today (20210727) is Debian 10 - codename Buster. Roughly about every three months/quarter of a year, Debian will publish a point release. This is genrally a round up of all the bug fixes and security fixes since the last point release. If you are keeping your machine up to date, then generally a point release will mean very little. Generally, there will be a bump to the base-files version and an increment on /etc/debian-version. So: Buster released with version 10.0 - with point releases, it's now up to 10.10. > Release Major release. Strictly, Debian has several releases in play at any one time. There is a section called Experimental which has a few packages but is not really a release - it's a staging area for experimental packages. Almost certainly for developers only or people on the very bleeding edge. There is always a subset of Debian that is Unstable - codename Sid. There's a release that is Testing - currently Bullseye - which will be Debian 11 when released.Under normal circumstances, packages would percolate from Unstable to Testing, but at the moment Testing is frozen for release when it's ready. There's the stable branch: Currently Buster - Debian 10.10. There's oldstable - Debian 9 - and oldoldstable - Debian 8 under support as either LTS or ELTS. > Update Packages update fairly regularly - security and other fixes.

If Bullseye gets released as Debian 11 on or about August 14th 2021 as planned - it will be the new stable, Buster will become oldstable, Stretch will become oldoldstable. The release after Bullseye will be called Bookworm. The release after that will be called Trixie. Debian codenames for releases are traditionally Toy Story character names. There's a whole lot more on this in wiki.debian.org / www.debian.org / Wikipedia or the Debian Handbook https://debian.handbook.info (or available as a Debian package debian-handbook). > Geg All best, Andy Cater
