 # Changelog
 
+## 1.2.0
+
+- Add `--tts-played-command`
+- Add `--mic-seconds-to-mute-after-awake-wav` and `--mic-no-mute-during-awake-wav`
+- Send preferred sound format to server
+
+## 1.1.1
+
+- Bump to wyoming 1.5.2 (package fix)
+
+## 1.1.0
+
+- Bump to wyoming 1.5.1
+- Send wyoming-satellite version in `info` message
+- Ping server if supported (faster awareness of disconnection)
+- Support `pause-satellite` message
+- Stop streaming/wake word detection as soon as `pause-satellite` is received or server disconnects
+- Mute microphone when awake WAV is playing
