Support

Current and the previous two one minor releases release will receive active support and security updates by the core development team. As of April 20202021, that means the 2.45.x, 2.34.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.Adopters who are running unsupported releases are encouraged to upgrade to supported releases. The Grouper development team will be happy to accept security patches for unsupported releases and make them publicly available to other adopters running unsupported releases. In addition, the Grouper development team will work with adopters running unsupported releases to assist on a best-effort basis with what would be needed for the adopter to develop their own patch against a known vulnerability.   Implementers should upgrade to a stable recent build of their supported version which is at most 3 months old.  Security fixes will prompt a new container build and the builds are linear so it is important to stay current.  In addition, the OS packages are in the container so it either requires a new container from Grouper or a new subimage to patch/upgrade the OS and related files.

Note: v2.5+ (while it is a supported version) will be updated at least monthly.  The v2.4 container is not receiving regular updates and requires a subimage build to get OS updates.
