If you have a working MythTV setup, and you want to try a newer version, both the software, and the database, need upgrading.
Usually, a newer version of the software will handle this automatically – even creating a database backup beforehand.
If you haven't upgraded in a long time, however, there might be problems. e.g. the program might say:
Your database version is too old to upgrade with this version of MythTV. You will need to use mythtv-setup from MythTV 0.22, 0.23, or 0.24 to upgrade your database before upgrading to this version of MythTV.

Finding your current version
Most mythtv programs give some useful information if you use the --version argument:
$ mythbackend --version Please attach all output as a file in bug reports. MythTV Version : v32.0+fixes.202211032049.18f5b48ee1~ubuntu22.04.1 MythTV Branch : fixes/32 Network Protocol : 91 Library API : 32.20200101-1 QT Version : 5.15.3 Options compiled in: linux profile use_hidesyms using_alsa using_oss using_pulse using_pulseoutput using_backend ...
or exit the front end and run:
$ mythfrontend --version Please attach all output as a file in bug reports. MythTV Version : v32.0+fixes.202211032049.18f5b48ee1~ubuntu22.04.1 MythTV Branch : fixes/32 Network Protocol : 91 Library API : 32.20200101-1 QT Version : 5.15.3 Options compiled in: linux profile use_hidesyms using_alsa using_oss using_pulse using_pulseoutput using_backend ...
but that doesn't help you to understand the database, or plugins.

If your current setup is older than 0.22, you will have to do a staged upgrade — first to 0.22, then to 0.28, or the latest (stable release, or someone's experimental branch).
Note that the database schemas for the plugins usually don't change as often.
KnoppMyth
KnoppMyth was a minimal Linux distribution for just creating a MythTV computer. This author (Nigel) would never have done any MythTV development if not for a fast and easy way to build a machine. It was replaced by a different distribution — LinHES — back in 2009.
This table lists many beta and final versions of KnoppMyth. Of limited use now, but just in case:

Towards the end, a nice graphical setup tool — MythVantage — was produced. This lives on, in LinHES:
LinHES
Information about LinHES releases (and KnoppMyth naming) is here.
Mythbuntu
For a while, a team was also producing customised Ubuntu releases that installed a stripped down Linux with MythTV. They also had a graphical management tool — Mythbuntu-Control-Centre.
Sadly, Mythbuntu has stopped being upgraded and supported. Read this.
