 # Changelog
 
+## 0.28.0
+
+**Release date:** 2022-12-21
+
+This prerelease removes all code references to `libgit2` and `git2go`, from
+this release onwards the controller will use `go-git` as the only git implementation.
+For more information, refer to version 0.27.0's changelog, which started `libgit2`'s
+deprecation process.
+
+The feature gate `ForceGoGitImplementation` was removed, users passing it as their
+controller's startup args will need to remove it before upgrading.
+
+Two new feature gates were introduced and are enabled by default:
+- `GitShallowClone`: enables the use of shallow clones when pulling source
+from Git repositories.
+- `GitAllBranchReferences`: enables users to toggle the download of all branch
+head references when push branches are configured.
+
+To opt-out from the feature gates above, start the controller with:
+`--feature-gates=GitShallowClone=false,GitAllBranchReferences=false`.
