+Airflow Helm Chart 1.8.0 (2023-02-02)
+-------------------------------------
+
+Significant Changes
+^^^^^^^^^^^^^^^^^^^
+
+``bitnami/postgresql`` subchart updated to ``12.1.9`` (#29071)
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The version of postgresql installed is still version 11.
+
+If you are upgrading an existing helm release with the built-in postgres
database, you will either need to delete your release and reinstall fresh, or
manually delete these 2 objects:
+
+```
+kubectl delete secret {RELEASE_NAME}-postgresql
+kubectl delete statefulset {RELEASE_NAME}-postgresql
+```
+
+As a reminder, it is recommended to `set up an external database
<https://airflow.apache.org/docs/helm-chart/stable/production-guide.html#database>`_
in production.
+
+This version of the chart uses different variable names for setting usernames
and passwords in the postgres database.
+
+- ``postgresql.auth.enablePostgresUser`` is used to determine if the
"postgres" admin account will be created.
+- ``postgresql.auth.postgresPassword`` sets the password for the "postgres"
user.
+- ``postgresql.auth.username`` and ``postrgesql.auth.password`` are used to
set credentials for a non-admin account if desired.
+- ``postgresql.postgresqlUsername`` and ``postgresql.postresqlPassword``,
which were used in the previous version of the chart, are no longer used.
+
+Users will need to make those changes in their values files if they are
changing the Postgres configuration.
+
+Previously the subchart version was ``10.5.3``.
+
+Default ``dags.gitSync.wait`` reduced to ``5`` seconds (#27625)
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The default for ``dags.gitSync.wait`` has been reduced from ``60`` seconds to
``5`` seconds to reduce the likelihood of DAGs
+becoming inconsistent between Airflow components. This will, however, increase
traffic to the remote git repository.
+
+Default Airflow image is updated to ``2.5.1`` (#29074)
+""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The default Airflow image that is used with the Chart is now ``2.5.1``,
previously it was ``2.4.1``.
+
+Default git-sync image is updated to ``3.6.3`` (#27848)
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The default git-sync image that is used with the Chart is now ``3.6.3``,
previously it was ``3.4.0``.
+
+Default redis image is updated to ``7-bullseye`` (#27443)
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The default git-sync image that is used with the Chart is now ``7-bullseye``,
previously it was ``6-bullseye``.
