+## 0.25.0
+
+**Release date:** 2022-06-01
+
+This prerelease adds support for Helm OCI. Users can specify `.spec.type` of
+a `HelmRepository` to use an OCI repository instead of an HTTP/S Helm repository.
+
+Please note that this currently has a couple of limitations (which will be addressed in a future release):
+* Chart dependencies from OCI repositories are not supported. [#722](https://github.com/fluxcd/source-controller/issues/722)
+* Custom CA certificates are not supported. [#723](https://github.com/fluxcd/source-controller/issues/723)
+
+An example of OCI `HelmRepository` can be found [here](https://github.com/fluxcd/source-controller/blob/api/v0.25.0/docs/spec/v1beta2/helmrepositories.md#helm-oci-repository).
+
+A new flag `--feature-gate` has been added to disable/enable new experimental
+features. It works in a similar manner to [Kubernetes feature gates](https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/).
+
+The libgit2 managed transport feature has been enabled by default. Furthermore,
+a few changes have been made to make the feature more stable and enable quicker
+clones. Users that want to opt out and use the unmanaged transports may do so
+by passing the flag `--feature-gate=GitManagedTransport=false`, but please note
+that we encourage users not to do so.
+
+GitRepository reconciliation has been made more efficient by adding support for
+no-op clones, when checking out repositories using branches or tags.
+This feature is also enabled by default, and users can opt out
+by passing the flag `--feature-gate=OptimizedGitClones=false`.
+Please note that this feature is only active when the managed transport feature
+is enabled. Disabling managed transports, quietly disables optimzed Git clones.

 This feature is enabled by default. It can be disabled by starting the
 controller with the argument `--feature-gates=OptimizedGitClones=false`.
