Since the developer meeting of April/May 2007, we decided that we should release versions more often. We, also, drew up a list of features which we consider to be important — tasks we need to do, before we feel comfortable releasing a 1·0 version. The results of those discussions are in the feature list spreadsheet.


Version Numbers

Version Numbering Definitions

Stellarium uses a three part version number: A·B·C where

Series version number. This remains at 0 until we feel we have all the basic functionality which is required for a feature-complete planetarium project. This core functionality is documented in the Stellarium tasklist document.
Major release number. Major release may include a lot of new functionality, or maybe just a re-worked internal structure. Either way, when this is incremented it’s a milestone of some sort. At major releases it is expected that compatibility with older major versions could be broken. This includes scripting commands, configuration options, command line options and work-flow within the program.
Service release number. Service releases are for bug fixes and may come with extra functionality as it is implemented. With a bit of luck, compatibility with previous service releases for the same major releases should be maintained.

Notable Versions

  • 0·10·0 beta. This release is tagged as a “beta” because the of the features which are missing: TUI, telescope control, scripting. The next version will be called 0·10·1, and should have at least a scripting engine.
  • 1·0·0. If we ever get here, it’ll be awesome. Somehow it always seems a few years off. Ho hum.



Released June 7 2007.


Released January 17th, 2008.

0·10·0 beta

Released September 24th, 2008.


Released February 6th, 2009. Focus: New scripting engine. API improvements and documentation.


Released on 10 March 2009. Uses Qt 4·5.


Released 30th January 2010, Built with Qt Creator on Qt 4·6·1.

0·10·4 For Windows

Released 23rd Febrary 2010, Built with Qt Creator 4·6·2.


Released 3rd June 2010 Windows, Mac, built with Qt 4·6·2.


Released on 6th December 2010. Two separate builds for Mac OS X, for Intel and PPC. The Windows package was repackaged a day after the initial release to include the Qt 4·7·1 libraries, so its version number was incremented to 0·10·6·1.


Released 2nd July 2011 new feature version, for testing features and providing bug fixes while work on 1·0·0 is completed.


A decision was made that the next version after 0·10·6 would be the long-awaited 1·0·0. (Unless there are significant bugs in 0·10·6 that warrant a bug fix release.)
