The Grouper Project Developers follow these guidelines regarding support and patching of previous releases:
Versioning:
The Grouper Development team strives to maintain permanent backward compatibility of the core API across all releases.
Security Fixes:
Current and the previous two Minor releases will receive active security patching by the core development team. As of August 2013 that means the 2.1.x, 2.0.x, and 1.6.x releases are maintained by the core development team. Releases outside of this window will be patched on a case-by-case basis depending on several factors including: ease of development/testing of a patch for the version, compatibility of a patch for a supported release being applied to an unsupported release, and community contributions of patches for a targeted unsupported version.
