+## [8.5.3] - 2022-01-10
+
+> 🟥 __Warning__ 🟥
+>
+> Update to this version if you are using Kubernetes 1.20+ to prevent the scheduler's liveness probe causing a restart loop (issue:[#484](https://github.com/airflow-helm/charts/issues/484)).
+> 
+> If you currently set `scheduler.livenessProbe.timeoutSeconds` or `pgbouncer.livenessProbe.timeoutSeconds` in your values, ensure you update them to the new default of `60`.
+
+### Changed
+- the default `airflow.image` is now `apache/airflow:2.1.4-python3.8`
+  - __NOTE:__ this does not affect support for older airflow versions, see the [airflow version support matrix](https://github.com/airflow-helm/charts/tree/main/charts/airflow#airflow-version-support)
+
+### Fixed
+- increase default `timeoutSeconds` for liveness probes ([#496](https://github.com/airflow-helm/charts/pull/496))
+- typo in `GIT_SYNC_MAX_SYNC_FAILURES` environment variable name ([#462](https://github.com/airflow-helm/charts/pull/462))
