A bit of planning ahead...

What are these release numbers?

  Version number scheme:
   * first number: major release number
   * secondary number: minor release number (stable/development indicator)
   * third number: revision 
 
  Using this scheme, version numbers have a very clear meaning:
   * new revision == bugs have been fixed, go grab it and install it.
   * new minor == new features are available, source compatibility _and_ binary 
         compatibility for existing applications are garanteed
   * new major == beware! Old (ugly) libraries have been dropped. Database 
         compatibility may be broken, you have to migrate your database to 
         the new formats and adjust your custom scripts (next is GRASS 7)
 
  It is important to regularly release stable versions to get them included into
  the major software distributions.
 
  Motivation: release often - try 1-2 stable releases per year

What are branches and tags?

Testing

GRASS 5.4.x

 Note: 5.4.x is a release branch, separated from HEAD. It's frozen.
 Only critical bugs are fixed in the 5.5-CVS repository "grass", HEAD
 (note: grass6/ is a separate repository).
  • GRASS 5.4.0 released 5 Nov 2004
  • GRASS 5.4.1 released 26 Jul 2007 (announcement) - Courtesy release containing several bug fixes for legacy users
    • supports GRASS 6 WIND files (3D region settings don't cause an error)
  • Post-5.4.1 (CVS, yet unreleased):
    • Fix definition of US survey foot
    • more precise conversions to feet, square miles and acres

GRASS 6.0.x

  Note: 6.0.x is a release branch, separated from HEAD. It's frozen and closed.
  • GRASS 6.0.0 released 10 Mar 2005
  • GRASS 6.0.1 released 22 Aug 2005
  • GRASS 6.0.2 released 22 Feb 2006
  • no longer actively maintained once 6.2.0 is published

GRASS 6.1.x

  Note: 6.1.x is a release branch (tag: "releasebranch_6_1"), separated from HEAD.
  It's frozen and closed.

GRASS 6.2.x

  Note: 6.2.x is a release branch (tag: "releasebranch_6_2"), separated from HEAD.
  It's frozen, only critical bugs will be fixed.

GRASS 6.3.x

Note: 6.3.0 "development preview" is a release branch (tag: "releasebranch_6_3"),
separated from HEAD. It's frozen, only important bugs will be fixed.
New developement is still open in 6.3-CVS, which is not a release branch.


  • 6.3.0RC1 released 24 Oct 2007
  • 6.3.0RC2 released 20 Nov 2007
  • 6.3.0RC3 released 30 Nov 2007
  • 6.3.0RC4 released 9 Jan 2008
  • 6.3.0RC5 released 19 Feb 2008
  • 6.3.0RC6 released 21 Mar 2008

GRASS 6.4.x

  • Once GRASS 7 development has started the 6.x line will work towards stability in advance of a final 6.4 stable branch, and new development should happen in the GRASS 7 SVN. Once work has started on preparing a 6.4 branch the GRASS 6 line will only be open to bug fixes and important enhancements.
  • Open to enhancements which do not break backwards compatibility with 6.x
  • 6.4 will include the new wxPython GUI but otherwise be very similar to 6.3.x
  • 6.4 will be the first stable version of GRASS to build natively for MS Windows.

GRASS 7.x
