The conference dedicated to API Platform and its ecosystem
Sep 15, 16 2022 | Lille & online
The Release Process
API Platform follows the Semantic Versioning strategy.
Only 3 versions are maintained at the same time:
- stable (currently the 2.6 branch): regular bug fixes are integrated in this version
- old-stable (currently 2.5 branch): security fixes are integrated in this version, regular bug fixes are not backported in it
- development (main branch): new features target this branch
Older versions (1.x, 2.0...) are not maintained. If you still use them, you must upgrade as soon as possible.
The old-stable branch is merged in the stable branch on a regular basis to propagate security fixes. The stable branch is merged in the development branch on a regular basis to propagate security and regular bug fixes.
New versions of API Platform are released when they are ready, on the behalf of the API Platform Core Team.
