Official Release


  • contains only validated new features
  • intended for productive usage
Stable Development
  • dev.xx versions are released during development when the performance is
    sufficiently stable; they contain bug fixes and some new features that still
    need to be validated
  • dev.betaxx versions are released in preparation to official releases for testing;
    no  new features are added to beta versions, only bug fixes
Nightly Build 1.14.0-dev
  • built daily with the latest additions to the code base that passed the standard
    regression tests
  • intended to make the latest developments and enhancements available for
    testers and developers, not for productive usage
  • features that are not subject to regression testing may get broken between
    one nightly build and the next
