 These builds are usually stable, but you may occasionally hit a broken version as these versions are not guaranteed to be deployed to [sentry.io](http://sentry.io/) first. There is also no guarantee that you will be able to do a clean upgrade to later versions without losing any data. **Use the nightly builds at your own risk.**

+## Breaking Changes
+
+- The `23.11.0` release will remove the ``sentry run smtp`` worker process. This
+  worker was not part of the standard self-hosted configuration, but could be
+  used in custom deployments.
