KDE neon offers a few different editions depending on what you’re interested in.
We’ve renamed our editions a bit as the current names were causing confusion. This affects the URLs used for repos and filenames used for installable ISOs and Docker images.
The editions are now:
User Edition: the main event, built from released tars of KDE software, continuously updated as soon as releases are made assuming all the QA tests pass (which sometimes they don’t and so it gets held back until we fix them). Use this if unsure.
Testing Edition: built from the beta Git branches of KDE apps (often the same as unstable), no automated QA, will contain bugs and breakage, useful for testing beta software. (Formerly Dev Stable Edition.)
Unstable Edition: built from unstable master Git branches of KDE apps, no automated QA, will contain bugs and muchos breakage, useful for testing features in development software. (Formerly Dev Unstable Edition.)
Developer Edition: An ISO with the unstable edition plus development headers pre-installed. Useful to not have to install all of Qt and KDE dev headers.
And some more obscure editions:
Pinebook Remix: an ARM64 build with a couple of non-free drivers for the Pinebook ARM laptop.
Plasma LTS Edition: formerly User LTS this is only useful for testing the Plasma LTS releases, everything else is still moving and updating so it’s no more stable or long supported than anything else.
Korean Edition: testing edition plus the Korean locale pre-configured for our friends in the far East.
Many people will want the User edition for the extra QA and then to use Docker images for testing. Or use the Docker images on any distro of course.
