+## [1.22.0](https://github.com/sqlc-dev/sqlc/releases/tag/1.22.0)
+Released 2023-09-26
+
+### Release notes
+
+#### Managed databses for `sqlc vet`
+
+If you're using [sqlc vet](../howto/vet.md) to write rules that require access to a running
+database, `sqlc` can now start and manage that database for you. PostgreSQL
+support is available today, with MySQL on the way.
+
+When you turn on managed databases, `sqlc` will use your schema to create a
+template database that it can copy to make future runs of `sqlc vet` very
+performant.
+
+This feature relies on configuration obtained via sqlc Cloud. If you're interested
+in early access you can [sign up here](https://docs.google.com/forms/d/e/1FAIpQLSdxoMzJ7rKkBpuez-KyBcPNyckYV-5iMR--FRB7WnhvAmEvKg/viewform)
+or send us an email at [hello@sqlc.dev](mailto:hello@sqlc.dev).
+
+Read more in the [managed databases](../howto/managed-databases.md) documentation.
