 ### Added
 
+- Introducing new interruption and speaking strategies. Interruption strategies
+  are used to indicate when the user should interrupt the bot (e.g. using VAD
+  events or when a user says one or more words). Speaking strategies are used to
+  indicate when the bot should start talking (e.g. using an end-of-turn
+  detection model, or checking how long until the last user transcription). In
+  conversational agents these are usually referred to start/stop speaking
+  policies or plans.
+
+  Available interruption strategies:
+    - VADInterruptionStrategy (default)
+    - MinWordsInterruptionStrategy
+
+  Avaliable speaking strategies:
+    - TranscriptionSpeakingStrategy (default)
+    - TurnAnalyzerSpeakingStrategy
+
+  To set these strategies you do it when setting up the `PipelineTask`, for
+  example:
+
+  ```python
+  task = PipelineTask(..., params=PipelineParams(
+      interruption_strategies=[MinWordsInterruptionStrategy(min_words=1)],
+      speaking_strategies=[
+          TurnAnalyzerSpeakingStrategy(
+              turn_analyzer=LocalSmartTurnAnalyzerV3(params=SmartTurnParams())
+          )
+      ],
+  ))
+  ```
+
+  In order to use the new interruption and speaking strategies you should update
+  to the new universal `LLMContext` and `LLMContextAggregatorPair`.
+
 - Added a `TTSService.includes_inter_frame_spaces` property getter, so that TTS
   services that subclass `TTSService` can indicate whether the text in the
   `TTSTextFrame`s they push already contain any necessary inter-frame spaces.
 
+### Deprecated
+
+- `pipecat.audio.interruptions.MinWordsInterruptionStrategy` is deprecated. Use
+  the new interruption and speaking strategies.
+
+- `TransportParams.turn_analyzer` is deprecated, use the new speaking strategies.
+
 ### Fixed
 
 - Fixed subtle issue of assistant context messages ending up with double spaces
