CHANGELOG.md

@@ -9,246 +9,17 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
-- 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
-
-- `PlayHTTTSService` uses the new v4 websocket API, which also fixes an issue
-  where text inputted to the TTS didn't return audio.
-
-- The default model for `ElevenLabsTTSService` is now `eleven_flash_v2_5`.
-
-- `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
-
-- `AWSTTSService` is now deprecated, use `PollyTTSService` instead.
-
-### Fixed
-
-- Fixed LLM response aggregators to support more uses cases such as delayed
-  transcriptions.
-
-- 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 [bug](https://github.com/pipecat-ai/pipecat/issues/868) in `DeepgramSTTService` that was causing Language to be passed
-  as python object instead of a string, causing 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
-
-### Added
-
-- Added `GeminiMultimodalLiveLLMService`. This is an integration for Google's
-  Gemini Multimodal Live API, supporting:
-
-  - Real-time audio and video input processing
-  - Streaming text responses with TTS
-  - Audio transcription for both user and bot speech
-  - Function calling
-  - System instructions and context management
-  - Dynamic parameter updates (temperature, top_p, etc.)
-
-- Added `AudioTranscriber` utility class for handling audio transcription with
-  Gemini models.
-
-- Added new context classes for Gemini:
-
-  - `GeminiMultimodalLiveContext`
-  - `GeminiMultimodalLiveUserContextAggregator`
-  - `GeminiMultimodalLiveAssistantContextAggregator`
-  - `GeminiMultimodalLiveContextAggregatorPair`
-
-- Added new foundational examples for `GeminiMultimodalLiveLLMService`:
-
-  - `26-gemini-multimodal-live.py`
-  - `26a-gemini-multimodal-live-transcription.py`
-  - `26b-gemini-multimodal-live-video.py`
-  - `26c-gemini-multimodal-live-video.py`
-
-- Added `SimliVideoService`. This is an integration for Simli AI avatars.
-  (see https://www.simli.com)
-
-- Added NVIDIA Riva's `FastPitchTTSService` and `ParakeetSTTService`.
-  (see https://www.nvidia.com/en-us/ai-data-science/products/riva/)
-
-- Added `IdentityFilter`. This is the simplest frame filter that lets through
-  all incoming frames.
-
-- New `STTMuteStrategy` called `FUNCTION_CALL` which mutes the STT service
-  during LLM function calls.
-
-- `DeepgramSTTService` now exposes two event handlers `on_speech_started` and
-  `on_utterance_end` that could be used to implement interruptions. See new
-  example `examples/foundational/07c-interruptible-deepgram-vad.py`.
-
-- Added `GroqLLMService`, `GrokLLMService`, and `NimLLMService` for Groq, Grok,
-  and NVIDIA NIM API integration, with an OpenAI-compatible interface.
-
-- New examples demonstrating function calling with Groq, Grok, Azure OpenAI,
-  Fireworks, and NVIDIA NIM: `14f-function-calling-groq.py`,
-  `14g-function-calling-grok.py`, `14h-function-calling-azure.py`,
-  `14i-function-calling-fireworks.py`, and `14j-function-calling-nvidia.py`.
-
-- In order to obtain the audio stored by the `AudioBufferProcessor` you can now
-  also register an `on_audio_data` event handler. The `on_audio_data` handler
-  will be called every time `buffer_size` (a new constructor argument) is
-  reached. If `buffer_size` is 0 (default) you need to manually get the audio as
-  before using `AudioBufferProcessor.merge_audio_buffers()`.
-
-```
-@audiobuffer.event_handler("on_audio_data")
-async def on_audio_data(processor, audio, sample_rate, num_channels):
-    await save_audio(audio, sample_rate, num_channels)
-```
-
 - Added a new RTVI message called `disconnect-bot`, which when handled pushes
   an `EndFrame` to trigger the pipeline to stop.
 
 ### Changed
 
-- `STTMuteFilter` now supports multiple simultaneous muting strategies.
-
-- `XTTSService` language now defaults to `Language.EN`.
-
-- `SoundfileMixer` doesn't resample input files anymore to avoid startup
-  delays. The sample rate of the provided sound files now need to match the
-  sample rate of the output transport.
-
-- Input frames (audio, image and transport messages) are now system frames. This
-  means they are processed immediately by all processors instead of being queued
-  internally.
-
 - Expanded the transcriptions.language module to support a superset of
   languages.
 
 - Updated STT and TTS services with language options that match the supported
   languages for each service.
 
-- Updated the `AzureLLMService` to use the `OpenAILLMService`. Updated the
-  `api_version` to `2024-09-01-preview`.
-
-- Updated the `FireworksLLMService` to use the `OpenAILLMService`. Updated the
-  default model to `accounts/fireworks/models/firefunction-v2`.
-
-- Updated the `simple-chatbot` example to include a Javascript and React client
-  example, using RTVI JS and React.
-
-### Removed
-
-- Removed `AppFrame`. This was used as a special user custom frame, but there's
-  actually no use case for that.
-
-### Fixed
-
-- Fixed a `ParallelPipeline` issue that would cause system frames to be queued.
-
-- Fixed `FastAPIWebsocketTransport` so it can work with binary data (e.g. using
-  the protobuf serializer).
-
-- Fixed an issue in `CartesiaTTSService` that could cause previous audio to be
-  received after an interruption.
-
-- Fixed Cartesia, ElevenLabs, LMNT and PlayHT TTS websocket
-  reconnection. Before, if an error occurred no reconnection was happening.
-
-- Fixed a `BaseOutputTransport` issue that was causing audio to be discarded
-  after an `EndFrame` was received.
-
-- Fixed an issue in `WebsocketServerTransport` and `FastAPIWebsocketTransport`
-  that would cause a busy loop when using audio mixer.
-
-- Fixed a `DailyTransport` and `LiveKitTransport` issue where connections were
-  being closed in the input transport prematurely. This was causing frames
-  queued inside the pipeline being discarded.
-
-- Fixed an issue in `DailyTransport` that would cause some internal callbacks to
-  not be executed.
-
-- Fixed an issue where other frames were being processed while a `CancelFrame`
-  was being pushed down the pipeline.
-
-- `AudioBufferProcessor` now handles interruptions properly.
-
-- Fixed a `WebsocketServerTransport` issue that would prevent interruptions with
-  `TwilioSerializer` from working.
-
-- `DailyTransport.capture_participant_video` now allows capturing user's screen
-  share by simply passing `video_source="screenVideo"`.
-
-- Fixed Google Gemini message handling to properly convert appended messages to
-  Gemini's required format.
-
-- Fixed an issue with `FireworksLLMService` where chat completions were failing
-  by removing the `stream_options` from the chat completion options.
-

-# Pipecat Documentation
-
-This directory contains the source files for auto-generating Pipecat's server API reference documentation.
-
-## Setup
-
-1. Install documentation dependencies:
-
-```bash
-pip install -r requirements.txt
-```
-
-2. Make the build scripts executable:
-
-```bash
-chmod +x build-docs.sh rtd-test.py
-```
-
-## Building Documentation
-
-From this directory, you can build the documentation in several ways:
-
-### Local Build
-
-```bash
-# Using the build script (automatically opens docs when done)
-./build-docs.sh
-
-# Or directly with sphinx-build
-sphinx-build -b html . _build/html -W --keep-going
-```
-
-### ReadTheDocs Test Build
-
-To test the documentation build process exactly as it would run on ReadTheDocs:
-
-```bash
-./rtd-test.py
-```
-
-This script:
-
-- Creates a fresh virtual environment
-- Installs all dependencies as specified in requirements files
-- Handles conflicting dependencies (like grpcio versions for Riva and PlayHT)
-- Builds the documentation in an isolated environment
-- Provides detailed logging of the build process
-
-Use this script to verify your documentation will build correctly on ReadTheDocs before pushing changes.
-
-## Viewing Documentation
-
-The built documentation will be available at `_build/html/index.html`. To open:
-
-```bash
-# On MacOS
-open _build/html/index.html
-
-# On Linux
-xdg-open _build/html/index.html
-
-# On Windows
-start _build/html/index.html
-```
-

-```
-
-## Notes
-
-- Documentation is auto-generated from Python docstrings
-- Service modules are automatically detected and included
-- The build process matches our ReadTheDocs configuration
-- Warnings are treated as errors (-W flag) to maintain consistency
-- The --keep-going flag ensures all errors are reported
-- Dependencies are split into multiple requirements files to handle version conflicts
-
-## Troubleshooting
-
-If you encounter missing service modules:
-
-1. Verify the service is installed with its extras: `pip install pipecat-ai[service-name]`
-2. Check the build logs for import errors
-3. Ensure the service module is properly initialized in the package
-4. Run `./rtd-test.py` to test in an isolated environment matching ReadTheDocs
-
-For dependency conflicts:
-
-1. Check the requirements files for version specifications
-2. Use `rtd-test.py` to verify dependency resolution
-3. Consider adding service-specific requirements files if needed
