+## [8.6.0] - 2022-04-13
+
+> 🟥 __WARNINGS__ 🟥
+>
+> - If you have `logs.persistence.enabled` set to `true`, you MUST disable `scheduler.logCleanup.enabled` and `workers.logCleanup.enabled` or the upgrade will fail
+> - If using airflow `2.0.X` or `2.1.X`, you should set `triggerer.enabled` to `false`, as the triggerer was added in airflow `2.2.0` and will fail in older versions
+> - If you currently pin `dags.gitSync.image.tag`, please update to the new default of `v3.5.0`
+> - If you currently pin `pgbouncer.image.tag`, please update to the new default of `1.17.0-patch.0`
+> - If you currently pin `pgbouncer.maxClientConnections`, please update to the new default of `1000`
+
+> 🟨 __NOTES__ 🟨
+>
+> - Consider enabling the new [Scheduler "task creation check"](docs/faq/monitoring/scheduler-liveness-probe.md#scheduler-task-creation-check) to prevent deadlocks, especially if using airflow versions before `2.1.1`
+> - If you disabled PgBouncer because of incompatibility with "Azure PostgreSQL", you can re-enable it if you [set `pgbouncer.authType = scram-sha-256` and `pgbouncer.serverSSL = verify-ca`](docs/faq/database/pgbouncer.md)
+> - This chart version fixes [an issue that caused `db-migrations` to hang](https://github.com/airflow-helm/charts/pull/529) when PgBouncer is enabled with airflow `2.2.0+`
+> - While NOT recommended, you can now set [external database](docs/faq/database/external-database.md) and [external redis](docs/faq/database/external-redis.md) passwords with a plain-text value
+> - If you are using [celery worker autoscaling](docs/faq/configuration/autoscaling-celery-workers.md), you must set a non-empty value for `workers.logCleanup.resources.requests`
+> - The new ["log-cleanup sidecar"](docs/faq/monitoring/log-cleanup.md) is enabled by default on schedulers and workers
+> - The new [PgBouncer startupProbe](https://github.com/airflow-helm/charts/pull/547) will only work in Kubernetes 1.18+
+> - The [`extraManifests` value](docs/faq/kubernetes/extra-manifests.md) has been significantly improved
