Policy

The Fedora project understands the importance of producing and maintaining secure, bug-free software. This policy defines the project's commitment in supporting previously released versions of the Fedora Repository software.

Presently, the codebase is evolving and settling, and the Fedora community has not yet fully transitioned to relying on any given 4.x release for production installations. Once this transition takes place, the Fedora project will institute a policy of continued support for previous major releases. Such a policy is not yet in effect, but this will be revisited on the date mentioned above.

titleSupport Policy

The Fedora Project does not currently have a policy of back-porting bug-fixes or security patches to previous 4.x releases.

Note: Unlike typical "semantic versioning", Fedora defines the following meaning to each of the three positions of a version number in a release such as: Fedora-4.1.2

Long Term Support (LTS) releases are Fedora releases targeting installations that favor known stability over the latest features.

LTS releases will be determined by the Fedora Committer and Leadership groups, with an estimated frequency of every other year.
LTS releases will come with the following guarantees:

  • 3 year period of support
  • Ensure stability of the API
  • Ensure compatibility with a supported version of the JVM per: Policy - Supported JVM
  • Ensure backporting of critical bug fixes and security patches
  • Provide documentation and tooling for migration from one LTS to the next

Current LTS Version: Fedora 6.x

  • As per a decision made during the December 8th, 2022 Governance meeting, it was decided that Fedora 6 would be considered the Long Term Support version of the software.


Notes:

As per Fedora Repository 3.8.1 Release Notes, Fedora 3.8.1 is the final release of the 3.x Branch and will no longer be maintained by the community. All users are encouraged to upgrade to the most current version of Fedora.

See Fedora 4 Semantic Versioning for description of versioning number scheme semantics.4 (in '4'.1.2) - product version (i.e. Fedora4, this number will not change unless there is a significant architectural shift in the Fedora application, as we saw from Fedora3 to 4).
1 (in 4.'1'.2) - major version (this number increments every time there is either a non-backwards compatible API change or an equally significant project milestone)
2 (in 4.1.'2') - combined minor version and bug-fix version (this number is incremented in the course of regular, frequent, maintenance releases)
