 ## Unreleased
 
 * [Changed] DogStatsD background sender queue now evicts the oldest queued payloads when full, and drops payloads without an explicit timestamp after they have been queued for more than 10 seconds. See [#986](https://github.com/DataDog/datadogpy/pull/986).
+* [Changed] Replace DogStatsD's `socket_connect_timeout` option with a boolean `socket_connect_retry`: when enabled, a UDS connection failure from the background sender is retried indefinitely with backoff instead of dropping the payload immediately. Also add an optional `timeout` parameter to `stop()` and `wait_for_pending()` to bound how long they wait for the queue to drain. See [#987](https://github.com/DataDog/datadogpy/pull/987).
