 - Added `GoogleHttpTTSService` which uses Google's HTTP TTS API.
 
+- Added `TavusTransport`, a new transport implementation compatible with any 
+  Pipecat pipeline. When using the `TavusTransport`the Pipecat bot will 
+  connect in the same room as the Tavus Avatar and the user.
+
+- Added `UserBotLatencyLogObserver`. This is an observer that logs the latency
+  between when the user stops speaking and when the bot starts speaking. This
+  gives you an initial idea on how quickly the AI services respond.
+
+- Added `SarvamTTSService`, which implements Sarvam AI's TTS API:
+  https://docs.sarvam.ai/api-reference-docs/text-to-speech/convert.

 - Added `PipelineTask.add_observer()` and `PipelineTask.remove_observer()` to

 - Updated `GoogleTTSService` to use Google's streaming TTS API. The default voice also updated to `en-US-Chirp3-HD-Charon`.
 
+- ⚠️Refactored the `TavusVideoService`, so it acts like a proxy, sending audio to 
+  Tavus and receiving both audio and video. This will make `TavusVideoService` usable
+  with any Pipecat pipeline and with any transport. This is a **breaking change**,
+  check the `examples/foundational/21a-tavus-layer-small-webrtc.py` to see how to
+  use it.
+
+- `DailyTransport` now uses custom microphone audio tracks instead of virtual
+  microphones. Now, multiple Daily transports can be used in the same process.
+
+- `DailyTransport` now captures audio from individual participants instead of
+  the whole room. This allows identifying audio frames per participant.

+- Updated the default model for `AnthropicLLMService` to

+- Updated the default model for `GeminiMultimodalLiveLLMService` to

 - `BaseTextFilter` methods `filter()`, `update_settings()`,
   `handle_interruption()` and `reset_interruption()` are now async.

 ### Fixed
 
+- Fixed a `DailyTransport` issue that would cause images needing resize to block

+- Fixed an issue with `ElevenLabsTTSService` where changing the model or voice
+  while the service is running wasn't working.

 - Fixed an issue that would cause multiple instances of the same class to behave
   incorrectly if any of the given constructor arguments defaulted to a mutable
   value (e.g. lists, dictionaries, objects).
