-## [Unreleased]
+## [0.0.54] - 2025-01-27
 
 ### Added
 
+- In order to create tasks in Pipecat frame processors it is now recommended to
+  use `FrameProcessor.create_task()` (which uses the new
+  `utils.asyncio.create_task()`). It takes care of uncaught exceptions, task
+  cancellation handling and task management. To cancel or wait for a task there
+  is `FrameProcessor.cancel_task()` and `FrameProcessor.wait_for_task()`. All of
+  Pipecat processors have been updated accordingly. Also, when a pipeline runner
+  finishes, a warning about dangling tasks might appear, which indicates if any
+  of the created tasks was never cancelled or awaited for (using these new
+  functions).
+
+- It is now possible to specify the period of the `PipelineTask` heartbeat
+  frames with `heartbeats_period_secs`.
+
+- Added `DailyMeetingTokenProperties` and `DailyMeetingTokenParams` Pydantic models
+  for meeting token creation in `get_token` method of `DailyRESTHelper`.
+
+- Added `enable_recording` and `geo` parameters to `DailyRoomProperties`.
+
+- Added `RecordingsBucketConfig` to `DailyRoomProperties` to upload recordings to a custom AWS bucket.
+
+### Changed
+
+- Enhanced `UserIdleProcessor` with retry functionality and control over idle
+  monitoring via new callback signature `(processor, retry_count) -> bool`.
+  Updated the `17-detect-user-idle.py` to show how to use the `retry_count`.
+
+- Add defensive error handling for `OpenAIRealtimeBetaLLMService`'s audio
+  truncation. Audio truncation errors during interruptions now log a warning
+  and allow the session to continue instead of throwing an exception.
+
+- Modified `TranscriptProcessor` to use TTS text frames for more accurate assistant
+  transcripts. Assistant messages are now aggregated based on bot speaking boundaries
+  rather than LLM context, providing better handling of interruptions and partial
+  utterances.
+
+- Updated foundational examples `28a-transcription-processor-openai.py`,
+  `28b-transcript-processor-anthropic.py`, and
+  `28c-transcription-processor-gemini.py` to use the updated
+  `TranscriptProcessor`.
+
+### Fixed
+
+- Fixed an `GeminiMultimodalLiveLLMService` issue that was preventing the user
+  to push initial LLM assistant messages (using `LLMMessagesAppendFrame`).
+
+- Added missing `FrameProcessor.cleanup()` calls to `Pipeline`,
+  `ParallelPipeline` and `UserIdleProcessor`.
+
+- Fixed a type error when using `voice_settings` in `ElevenLabsHttpTTSService`.
+
+- Fixed an issue where `OpenAIRealtimeBetaLLMService` function calling resulted
+  in an error.
+
+- Fixed an issue in `AudioBufferProcessor` where the last audio buffer was not
+  being processed, in cases where the `_user_audio_buffer` was smaller than the
+  buffer size.
+
+### Performance
+
+- Replaced audio resampling library `resampy` with `soxr`. Resampling a 2:21s
+  audio file from 24KHz to 16KHz took 1.41s with `resampy` and 0.031s with
+  `soxr` with similar audio quality.
+
+### Other
+
+- Added initial unit test infrastructure.
+
+## [0.0.53] - 2025-01-18
+
+### Added
+
+- Added `ElevenLabsHttpTTSService` which uses EleveLabs' HTTP API instead of the
+  websocket one.
+
+- Introduced pipeline frame observers. Observers can view all the frames that go
+  through the pipeline without the need to inject processors in the
+  pipeline. This can be useful, for example, to implement frame loggers or
+  debuggers among other things. The example
+  `examples/foundational/30-observer.py` shows how to add an observer to a
+  pipeline for debugging.
+
+- Introduced heartbeat frames. The pipeline task can now push periodic
+  heartbeats down the pipeline when `enable_heartbeats=True`. Heartbeats are
+  system frames that are supposed to make it all the way to the end of the
+  pipeline. When a heartbeat frame is received the traversing time (i.e. the
+  time it took to go through the whole pipeline) will be displayed (with TRACE
+  logging) otherwise a warning will be shown. The example
+  `examples/foundational/31-heartbeats.py` shows how to enable heartbeats and
+  forces warnings to be displayed.
+
+- Added `LLMTextFrame` and `TTSTextFrame` which should be pushed by LLM and TTS
+  services respectively instead of `TextFrame`s.
+
+- Added `OpenRouter` for OpenRouter integration with an OpenAI-compatible
+  interface. Added foundational example `14m-function-calling-openrouter.py`.
+
+- Added a new `WebsocketService` based class for TTS services, containing
+  base functions and retry logic.
+
+- Added `DeepSeekLLMService` for DeepSeek integration with an OpenAI-compatible
+  interface. Added foundational example `14l-function-calling-deepseek.py`.
+
+- Added `FunctionCallResultProperties` dataclass to provide a structured way to
+  control function call behavior, including:
+
+  - `run_llm`: Controls whether to trigger LLM completion
+  - `on_context_updated`: Optional callback triggered after context update
+
+- Added a new foundational example `07e-interruptible-playht-http.py` for easy
+  testing of `PlayHTHttpTTSService`.
+
+- Added support for Google TTS Journey voices in `GoogleTTSService`.
+
+- Added `29-livekit-audio-chat.py`, as a new foundational examples for
+  `LiveKitTransportLayer`.
+
+- Added `enable_prejoin_ui`, `max_participants` and `start_video_off` params
+  to `DailyRoomProperties`.
+
+- Added `session_timeout` to `FastAPIWebsocketTransport` and
+  `WebsocketServerTransport` for configuring session timeouts (in
+  seconds). Triggers `on_session_timeout` for custom timeout handling.
+  See [examples/websocket-server/bot.py](https://github.com/pipecat-ai/pipecat/blob/main/examples/websocket-server/bot.py).
+
+- Added the new modalities option and helper function to set Gemini output
+  modalities.
+
+- Added `examples/foundational/26d-gemini-multimodal-live-text.py` which is
+  using Gemini as TEXT modality and using another TTS provider for TTS process.
+
+### Changed
+
+- Modified `UserIdleProcessor` to start monitoring only after first
+  conversation activity (`UserStartedSpeakingFrame` or
+  `BotStartedSpeakingFrame`) instead of immediately.
+
+- Modified `OpenAIAssistantContextAggregator` to support controlled completions
+  and to emit context update callbacks via `FunctionCallResultProperties`.
+
+- Added `aws_session_token` to the `PollyTTSService`.
+
+- Changed the default model for `PlayHTHttpTTSService` to `Play3.0-mini-http`.
+
+- `api_key`, `aws_access_key_id` and `region` are no longer required parameters
+  for the PollyTTSService (AWSTTSService)
+
+- Added `session_timeout` example in `examples/websocket-server/bot.py` to
+  handle session timeout event.
+
+- Changed `InputParams` in
+  `src/pipecat/services/gemini_multimodal_live/gemini.py` to support different
+  modalities.
+
+- Changed `DeepgramSTTService` to send `finalize` event whenever VAD detects
+  `UserStoppedSpeakingFrame`. This helps in faster transcriptions and clearing
+  the `Deepgram` audio buffer.
+
+### Fixed
+
+- Fixed an issue where `DeepgramSTTService` was not generating metrics using
+  pipeline's VAD.
+
+- Fixed `UserIdleProcessor` not properly propagating `EndFrame`s through the
+  pipeline.
+
+- Fixed an issue where websocket based TTS services could incorrectly terminate
+  their connection due to a retry counter not resetting.
+
+- Fixed a `PipelineTask` issue that would cause a dangling task after stopping
+  the pipeline with an `EndFrame`.
+
+- Fixed an import issue for `PlayHTHttpTTSService`.
+
+- Fixed an issue where languages couldn't be used with the `PlayHTHttpTTSService`.
+
+- Fixed an issue where `OpenAIRealtimeBetaLLMService` audio chunks were hitting
+  an error when truncating audio content.
+
+- Fixed an issue where setting the voice and model for `RimeHttpTTSService`
+  wasn't working.
+
+- Fixed an issue where `IdleFrameProcessor` and `UserIdleProcessor` were getting
+  initialized before the start of the pipeline.
+
+## [0.0.52] - 2024-12-24
+
+### Added
+
+- Constructor arguments for GoogleLLMService to directly set tools and tool_config.
+
+- Smart turn detection example (`22d-natural-conversation-gemini-audio.py`) that
+  leverages Gemini 2.0 capabilities ().
+  (see https://x.com/kwindla/status/1870974144831275410)
+
+- Added `DailyTransport.send_dtmf()` to send dial-out DTMF tones.
+
+- Added `DailyTransport.sip_call_transfer()` to forward SIP and PSTN calls to
+  another address or number. For example, transfer a SIP call to a different
+  SIP address or transfer a PSTN phone number to a different PSTN phone number.
+
+- Added `DailyTransport.sip_refer()` to transfer incoming SIP/PSTN calls from
+  outside Daily to another SIP/PSTN address.
+
+- Added an `auto_mode` input parameter to `ElevenLabsTTSService`. `auto_mode`
+  is set to `True` by default. Enabling this setting disables the chunk
+  schedule and all buffers, which reduces latency.
+
+- Added `KoalaFilter` which implement on device noise reduction using Koala
+  Noise Suppression.
+  (see https://picovoice.ai/platform/koala/)
+
+- Added `CerebrasLLMService` for Cerebras integration with an OpenAI-compatible
+  interface. Added foundational example `14k-function-calling-cerebras.py`.
+
+- Pipecat now supports Python 3.13. We had a dependency on the `audioop` package
+  which was deprecated and now removed on Python 3.13. We are now using
+  `audioop-lts` (https://github.com/AbstractUmbra/audioop) to provide the same
+  functionality.
+
+- Added timestamped conversation transcript support:
+
+  - New `TranscriptProcessor` factory provides access to user and assistant
+    transcript processors.
+  - `UserTranscriptProcessor` processes user speech with timestamps from
+    transcription.
+  - `AssistantTranscriptProcessor` processes assistant responses with LLM
+    context timestamps.
+  - Messages emitted with ISO 8601 timestamps indicating when they were spoken.
+  - Supports all LLM formats (OpenAI, Anthropic, Google) via standard message
+    format.
+  - New examples: `28a-transcription-processor-openai.py`,
+    `28b-transcription-processor-anthropic.py`, and
+    `28c-transcription-processor-gemini.py`.
+
 - Add support for more languages to ElevenLabs (Arabic, Croatian, Filipino,
   Tamil) and PlayHT (Afrikans, Albanian, Amharic, Arabic, Bengali, Croatian,
   Galician, Hebrew, Mandarin, Serbian, Tagalog, Urdu, Xhosa).
 
 ### Changed
 
-- It's no longer necessary to call `super().start/stop/cancel(frame)` if you
+- `PlayHTTTSService` uses the new v4 websocket API, which also fixes an issue
-  subclass and implement `AIService.start/stop/cancel()`. This is all now done
+  where text inputted to the TTS didn't return audio.
-  internally and will avoid possible issues if you forget to add it.
 
-- It's no longer necessary to call `super().process_frame(frame, direction)` if
+- The default model for `ElevenLabsTTSService` is now `eleven_flash_v2_5`.
-  you subclass and implement `FrameProcessor.process_frame()`. This is all now
+
-  done internally and will avoid possible issues if you forget to add it.
+- `OpenAIRealtimeBetaLLMService` now takes a `model` parameter in the
+  constructor.
+
+- Updated the default model for the `OpenAIRealtimeBetaLLMService`.
+
+- Room expiration (`exp`) in `DailyRoomProperties` is now optional (`None`) by
+  default instead of automatically setting a 5-minute expiration time. You must
+  explicitly set expiration time if desired.
 
 ### Deprecated
 
@@ -29,12 +269,33 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Fixed
 
+- Fixed token counting in `GoogleLLMService`. Tokens were summed incorrectly
+  (double-counted in many cases).
+
+- Fixed an issue that could cause the bot to stop talking if there was a user
+  interruption before getting any audio from the TTS service.
+
+- Fixed an issue that would cause `ParallelPipeline` to handle `EndFrame`
+  incorrectly causing the main pipeline to not terminate or terminate too early.
+
+- Fixed an audio stuttering issue in `FastPitchTTSService`.
+
 - Fixed a `BaseOutputTransport` issue that was causing non-audio frames being
   processed before the previous audio frames were played. This will allow, for
   example, sending a frame `A` after a `TTSSpeakFrame` and the frame `A` will
   only be pushed downstream after the audio generated from `TTSSpeakFrame` has
   been spoken.
 
+- Fixed a `DeepgramSTTService` issue that was causing language to be passed as
+  an object instead of a string resulting in the connection to fail.
+
+## [0.0.51] - 2024-12-16
+
+### Fixed
+
+- Fixed an issue in websocket-based TTS services that was causing infinite
+  reconnections (Cartesia, ElevenLabs, PlayHT and LMNT).
+
 ## [0.0.50] - 2024-12-11

-# Dialin example
-
-Example project that demonstrates how to add phone number dialin to your Pipecat bots. We include examples for both Daily (`bot_daily.py`) and Twilio (`bot_twilio.py`), depending on who you want to use as a phone vendor.
-
-- 🔁 Transport: Daily WebRTC
-- 💬 Speech-to-Text: Deepgram via Daily transport
-- 🤖 LLM: GPT4-o / OpenAI
-- 🔉 Text-to-Speech: ElevenLabs
-
-#### Should I use Daily or Twilio as a vendor?
-
-If you're starting from scratch, using Daily to provision phone numbers alongside Daily as a transport offers some convenience (such as automatic call forwarding.)
-
-If you already have Twilio numbers and workflows that you want to connect to your Pipecat bots, there is some additional configuration required (you'll need to create a `on_dialin_ready` and use the Twilio client to trigger the forward.)
-
-You can read more about this, as well as see respective walkthroughs in our docs.
-
-## Setup
-
-```shell
-# Install the requirements
-pip install -r requirements.txt
-
-# Setup your env
-mv env.example .env
-```
-
-## Using Daily numbers
-
-Run `bot_runner.py` to handle incoming HTTP requests:
-
-`python bot_runner.py --host localhost`
-
-Then target the following URL:
-
-`POST /daily_start_bot`
-
-For more configuration options, please consult Daily's API documentation.
-
-
-## Using Twilio numbers
-
-As above, but target the following URL:
-
-`POST /twilio_start_bot`
-
-For more configuration options, please consult Twilio's API documentation.
-
-## Deployment example
-
-A Dockerfile is included in this demo for convenience. Here is an example of how to build and deploy your bot to [fly.io](https://fly.io).
-
-*Please note: This demo spawns agents as subprocesses for convenience / demonstration purposes. You would likely not want to do this in production as it would limit concurrency to available system resources. For more information on how to deploy your bots using VMs, refer to the Pipecat documentation.*
-
-### Build the docker image
-
-`docker build -t tag:project .`
-
-### Launch the fly project
-
-`mv fly.example.toml fly.toml`
-
-`fly launch` (using the included fly.toml)
-
-### Setup your secrets on Fly
-
-Set the necessary secrets (found in `env.example`)
-
-`fly secrets set DAILY_API_KEY=... OPENAI_API_KEY=... ELEVENLABS_API_KEY=... ELEVENLABS_VOICE_ID=...`
-
-If you're using Twilio as a number vendor:
-
-`fly secrets set TWILIO_ACCOUNT_SID=... TWILIO_AUTH_TOKEN=...`
-
-### Deploy!
-
-`fly deploy`
-
-## Need to do something more advanced?
-
-This demo covers the basics of bot telephony. If you want to know more about working with PSTN / SIP, please ping us on [Discord](https://discord.gg/pipecat).
