Fixed

- Fixed an issue handling Daily transport `dialin-ready` event.

Added

- Added Daily transport `start_dialout()` to be able to make phone or SIP calls.
See https://reference-python.daily.co/api_reference.html#daily.CallClient.start_dialout

- Added Daily transport support for dial-in use cases.

- Added Daily transport events: `on_dialout_connected`, `on_dialout_stopped`,
`on_dialout_error` and `on_dialout_warning`. See
https://reference-python.daily.co/api_reference.html#daily.EventHandler

Added

- Added vision support to Anthropic service.

- Added `WakeCheckFilter` which allows you to pass information downstream only
if you say a certain phrase/word.

Changed

- `Filter` has been renamed to `FrameFilter` and it's now under
`processors/filters`.

Fixed

- Fixed Anthropic service to use new frame types.

- Fixed an issue in `LLMUserResponseAggregator` and `UserResponseAggregator`
that would cause frames after a brief pause to not be pushed to the LLM.

- Clear the audio output buffer if we are interrupted.

- Re-add exponential smoothing after volume calculation. This makes sure the
volume value being used doesn't fluctuate so much.

Added

- In order to improve interruptions we now compute a loudness level using
[pyloudnorm](https://github.com/csteinmetz1/pyloudnorm). The audio coming
WebRTC transports (e.g. Daily) have an Automatic Gain Control (AGC) algorithm
applied to the signal, however we don't do that on our local PyAudio
signals. This means that currently incoming audio from PyAudio is kind of
broken. We will fix it in future releases.

Fixed

- Fixed an issue where `StartInterruptionFrame` would cause
`LLMUserResponseAggregator` to push the accumulated text causing the LLM
respond in the wrong task. The `StartInterruptionFrame` should not trigger any
new LLM response because that would be spoken in a different task.

- Fixed an issue where tasks and threads could be paused because the executor
didn't have more tasks available. This was causing issues when cancelling and
recreating tasks during interruptions.

Changed

- `LLMUserResponseAggregator` and `LLMAssistantResponseAggregator` internal
messages are now exposed through the `messages` property.

Fixed

- Fixed an issue where `LLMAssistantResponseAggregator` was not accumulating the
full response but short sentences instead. If there's an interruption we only
accumulate what the bot has spoken until now in a long response as well.

Fixed

- Fixed an issue in `DailyOuputTransport` where transport messages were not
being sent.
