   `filter_code` to filter code from text and `filter_tables` to filter tables

+  `AudioBufferProcessor` to capture conversation audio and later send it to
+  Canonical AI.
+  (see https://canonical.chat/)
+
+- Added `AudioBufferProcessor`. This processor can be used to buffer mixed user and

 ### Fixed
 
 - Merge `RTVIBotLLMProcessor`/`RTVIBotLLMTextProcessor` and
   `RTVIBotTTSProcessor`/`RTVIBotTTSTextProcessor` to avoid out of order issues.
 
+- Fixed an issue in RTVI protocol that could cause a `bot-llm-stopped` or
+  `bot-tts-stopped` message to be sent before a `bot-llm-text` or `bot-tts-text`
+  message.
+
+- Fixed `DeepgramSTTService` constructor settings not being merged with default
+  ones.
+
 - Fixed an issue in Daily transport that would cause tasks to be hanging if
   urgent transport messages were being sent from a transport event handler.
 
+- Fixed an issue in `BaseOutputTransport` that would cause `EndFrame` to be
+  pushed downed too early and call `FrameProcessor.cleanup()` before letting the
+  transport stop properly.
