Release Schedule

There have been considerable accuracy improvements since the 0.12 series, and finally the current developers feel Stellarium is accurate enough to be called "astronomically complete". IN addition, Stellarium can be built with the upgraded Qt6 framework. Therefore version number 1.0 has been released instead of 0.23.3. Version numbering especially for the beta versions have confused some users in the past.

As of 2019, the version numbers include 2 places of the calendar year. There are usually four releases of Stellarium per year, usually around the solstices and equinoxes. These are now called 0.YY.0 for a release near March equinox, 0.YY.1 around June solstice, 0.YY.2 around September equinox, and 0.YY.3 around December solstice. Occasionally, a patch release like 0.19.1.1 will appear. In rare cases, more releases may appear (e.g. 0.20.1 and 0.22.1 were early).

The 1.0 release brought new variants. 1.0 is actually a symbolic label for both "0.22.3" (Qt5 based) and "1.22.3" (Qt6 based). We will for some time build 0.YY.N and 1.YY.N in parallel, the 0 series geared towards older or officially obsolete systems.

Between these releases, there are beta versions (a weekly snapshots) built almost every weekend which include the latest changes, but which may not be stable or may show unusual behaviour. These show a gray splash screen and have version numbers that show the latest official version number with hash of revision (or an ever growing build number) added, like 1.22.3-410abbe. Those published on the weekends before a release is due may carry the additional "Release Candidate" tag (RC).
