This page documents tagged releases of the seL4 kernel and proofs, for documentation on the release process we follow see here.
This section documents the version at which specific features were introduced to seL4. For future features, see seL4 status. For other previous features, see the release notes below.
Verification Status carries the following definitions and refers to the version specified in the verification manifest tagged for that specific release.
- No: As of this release, this feature is not verified.
- FC: the functional correctness proofs are complete.
- FCI: the integrity proofs are complete, in addition to functional correctness.
- Yes: this feature has functional correctness, integrity and infoflow proofs completed, for verified platforms, as of this release.
For the verification status of all platforms, see Hardware.
