Synapse 1.32.0 (2021-04-20)
===========================
+**Note:** This release introduces [a regression](https://github.com/matrix-org/synapse/issues/9853)
+that can overwhelm connected Prometheus instances. This issue was not present in
+1.32.0rc1, and is fixed in 1.32.1. See the changelog for 1.32.1 above for more information.
+
**Note:** This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.
This release removes the deprecated `GET /_synapse/admin/v1/users/<user_id>` admin API. Please use the [v2 API](https://github.com/matrix-org/synapse/blob/develop/docs/admin_api/user_admin_api.rst#query-user-account) instead, which has improved capabilities.
