+## [8.7.0] - 2023-04-06
+
+> 🟥 __WARNINGS__ 🟥
+>
+> - if you use a custom `pgbouncer.image.tag`, you MUST update it to `1.18.0-patch.1` or later, as we now require the `openssl` package to be installed for generating self-signed certificates
+> - if you use a custom `postgresql.image`, please take note that `postgresql.image.registry` is now `ghcr.io` by default (rather than `docker.io`)
+> - if you use "Azure File" for logs persistence, you MUST NOT update to airflow 2.5.1, 2.5.2, or 2.5.3:
+>    - there is an [issue in these versions](https://github.com/apache/airflow/issues/29112) that will cause your tasks to fail
+>    - if you wish to use these versions, you will need to use a different method of logs persistence, for example [the `Azure Blob Storage` remote provider](https://github.com/airflow-helm/charts/blob/main/charts/airflow/docs/faq/monitoring/log-persistence.md#option-2---remote-providers)
+
+> 🟨 __NOTES__ 🟨
+>
+> - the default airflow image is now `apache/airflow:2.5.3-python3.8`, but you can still use any supported version of airflow, see the [airflow version support matrix](https://github.com/airflow-helm/charts/tree/main/charts/airflow#airflow-version-support)
+> - when upgrading to airflow 2.5, you may wish to rename your kubernetes `aiflow.config` from `AIRFLOW__KUBERNETES__*` to `AIRFLOW__KUBERNETES_EXECUTOR__*`, as the former was deprecated by airflow 2.5
+> - the chart should no longer be forever "out of sync" in apps like ArgoCD, as this issue was resolved by [#718](https://github.com/airflow-helm/charts/pull/718)

+- the default embedded redis image is now `bitnami/redis:5.0.14-debian-10-r173`

+
+### Fixed
+- ensure Kubernetes 1.25+ support by updating default api versions for `PodDisruptionBudget` and `HorizontalPodAutoscaler` ([#685](https://github.com/airflow-helm/charts/pull/685))
