Added

• Added Whisker frames: WhiskerFrame and WhiskerUrgentFrame. These frames are used to communicate with Whisker directly, rather than being part of the standard pipeline flow. They will be displayed in a different color so it's easier to distinguish them. They can be used as a mark to to know when something happened and easily see it in the Whisker client.

Fixed

• Fixed a Whisker client issue that was causing a switch between light/dark themes when pressing 'd' inside the filter.

Added

• The Whisker client now displays Whisker/Pipecat/Python/Platform versions. This can be useful to know in which system the observer is/was running.

Fixed

• Fixed an issue that would cause the client to display a blank page (with an error in the console) when loading a file after a previous network session was already loaded.

Changed

• We now just write one single file instead of one per client session.

  whisker = WhiskerObserver(pipeline, file_name="whisker.bin")

Fixed

• Fixed a client issue that was causing the pipeline to be reset when receiving messages.

Added

• Allow saving sessions into a file and load them with the Whisker client.

Changed

• Whisker now uses msgpack for streaming messages instead of JSON.

Fixed

• Fixed an issue where processor flashing would be delayed.

Changed

• WhiskerObserver serializer function now gets an initial BaseObserver argument.

  def serializer(observer: BaseObserver, frame: Frame)

  instead of

  def serializer(frame: Frame)

Fixed

• Fixed a WhiskerObserver serialization issue and catch exceptions if serialization fails.

• Fixed an issue that would prevent WhiskerObserver from shutting down the pipeline. Needs pipecat-ai > 0.0.82.

Performance

• Avoid WhiskerObserver deepcopy and simply serialize fields.

Added

• Added the ability to pass custom serializer to WhiskerObserver via the serializer argument.

• Added batch_size argument to WhiskerObserver to indicate the maximum batch to buffer before sending a message to the client.

• Added a note to indicate that frames are buffered when the client is disconnected. This may cause memory growth on the server side.

Fixed

• Fixed a WhiskerObserver where some frames would not be serialized properly.

Changed

• Ignore InputAudioRawFrame by default instead of UserAudioRawFrame which are less generic.

Fixed

• Fixed a WhiskerObserver issue that required a greater websockets version other than the specified one.

Fixed

• Cleanup frames and frame paths when a new pipeline is sent, and also cleanup selected elements.

• Fixed an issue in WhiskerObserver that would serialize strings as str instead of the actual string.

Initial public release.
