+Version 5.0-post-dev-10-g3888999d
+==
+* Remove requirement for the `mosquitto` service to be running when Shairport Sync is built with the `--with-mqtt-client` configuration flag. The service does not, in fact, need to be running in every case.
+This reverses a change made in [PR](https://github.com/mikebrady/shairport-sync/pull/2137) at [Version 5.0-dev-161](https://github.com/mikebrady/shairport-sync/blob/development/RELEASENOTES-DEVELOPMENT.md#version-50-dev-161-g5b3659c2).

+  Thanks to [David Crook](https://github.com/idcrook) for the [bug report](https://github.com/mikebrady/shairport-sync/issues/2150).
