+## 0.21.0
+
+**Release date:** 2022-01-26
+
+This prerelease comes with changes to the base image used to build and
+run the controller, replacing Debian Unstable (Sid) with Alpine 3.15.
+The controller is now statically built and includes libgit2 along with
+its main dependencies.
+
+The controller container images are signed with
+[Cosign and GitHub OIDC](https://github.com/sigstore/cosign/blob/22007e56aee419ae361c9f021869a30e9ae7be03/KEYLESS.md),
+and a Software Bill of Materials in [SPDX format](https://spdx.dev) has been published on the release page.
+
+Starting with this version, the controller deployment conforms to the
+Kubernetes [restricted pod security standard](https://kubernetes.io/docs/concepts/security/pod-security-standards/#restricted):
+- all Linux capabilities were dropped
+- the root filesystem was set to read-only
+- the seccomp profile was set to the runtime default
+- run as non-root was enabled
+- the filesystem group was set to 1337
+- the user and group ID was set to 65534
+
+**Breaking changes**:
+- The use of new seccomp API requires Kubernetes 1.19.
+- The controller container is now executed under 65534:65534 (userid:groupid).
+  This change may break deployments that hard-coded the user ID of 'controller' in their PodSecurityPolicy.
