 ### Added

- ElevenLabs TTS services now support a sample rate of 8000.
+- Added a new iOS client option to the `SmallWebRTCTransport` **video-transform** example.
+
+- Added new processors `ProducerProcessor` and `ConsumerProcessor`. The
+  producer processor processes frames from the pipeline and decides whether the
+  consumers should consume it or not. If so, the same frame that is received by
+  the producer is sent to the consumer. There can be multiple consumers per
+  producer. These processors can be useful to push frames from one part of a
+  pipeline to a different one (e.g. when using `ParallelPipeline`).
+
+- Improvements for the `SmallWebRTCTransport`:
+  - Wait until the pipeline is ready before triggering the `connected` event.
+  - Queue messages if the data channel is not ready.
+  - Update the aiortc dependency to fix an issue where the 'video/rtx' MIME
+    type was incorrectly handled as a codec retransmission.
+  - Avoid initial video delays.

 ### Fixed

+- Fixed an issue in the Azure TTS services where the language was being set
+  incorrectly.
+
+- Fixed `SmallWebRTCTransport` to support dynamic values for
+  `TransportParams.audio_out_10ms_chunks`. Previously, it only worked with 20ms
+  chunks.
+
+- Fixed an issue where `LLMAssistantContextAggregator` would prevent a
+  `BotStoppedSpeakingFrame` from moving through the pipeline.
+
+## [0.0.62] - 2025-04-01 "An April Fools' release"
+
+### Added
+
+- Added `TransportParams.audio_out_10ms_chunks` parameter to allow controlling
+  the amount of audio being sent by the output transport. It defaults to 4, so
+  40ms audio chunks are sent.
+
+- Added `QwenLLMService` for Qwen integration with an OpenAI-compatible
+  interface. Added foundational example `14q-function-calling-qwen.py`.
+
+- Added `Mem0MemoryService`. Mem0 is a self-improving memory layer for LLM
+  applications. Learn more at: https://mem0.ai/.
+
+- Added `WhisperSTTServiceMLX` for Whisper transcription on Apple Silicon.
+  See example in `examples/foundational/13e-whisper-mlx.py`. Latency of
+  completed transcription using Whisper large-v3-turbo on an M4 macbook is
+  ~500ms.
+
+- Added `SmallWebRTCTransport`, a new P2P WebRTC transport.
+
+  - Created two examples in `p2p-webrtc`:
+    - **video-transform**: Demonstrates sending and receiving audio/video with
+      `SmallWebRTCTransport` using `TypeScript`. Includes video frame
+      processing with OpenCV.
+    - **voice-agent**: A minimal example of creating a voice agent with
+      `SmallWebRTCTransport`.
+
+- `GladiaSTTService` now have comprehensive support for the latest API config
+  options, including model, language detection, preprocessing, custom
+  vocabulary, custom spelling, translation, and message filtering options.
+
+- Added `SmallWebRTCTransport`, a new P2P WebRTC transport.
+
+  - Created two examples in `p2p-webrtc`:
+    - **video-transform**: Demonstrates sending and receiving audio/video with
+      `SmallWebRTCTransport` using `TypeScript`. Includes video frame
+      processing with OpenCV.
+    - **voice-agent**: A minimal example of creating a voice agent with
+      `SmallWebRTCTransport`.
+
+- Added support to `ProtobufFrameSerializer` to send the messages from
+  `TransportMessageFrame` and `TransportMessageUrgentFrame`.
+
+- Added support for a new TTS service, `PiperTTSService`.
+  (see https://github.com/rhasspy/piper/)
+
+- It is now possible to tell whether `UserStartedSpeakingFrame` or
+  `UserStoppedSpeakingFrame` have been generated because of emulation frames.
+
+### Changed
+
+- `FunctionCallResultFrame`a are now system frames. This is to prevent function
+  call results to be discarded during interruptions.
+
+- Pipecat services have been reorganized into packages. Each package can have
+  one or more of the following modules (in the future new module names might be
+  needed) depending on the services implemented:
+
+  - image: for image generation services
+  - llm: for LLM services
+  - memory: for memory services
+  - stt: for Speech-To-Text services
+  - tts: for Text-To-Speech services
+  - video: for video generation services
+  - vision: for video recognition services
+
+- Base classes for AI services have been reorganized into modules. They can now
+  be found in
+  `pipecat.services.[ai_service,image_service,llm_service,stt_service,vision_service]`.
+
+- `GladiaSTTService` now uses the `solaria-1` model by default. Other params
+  use Gladia's default values. Added support for more language codes.
+
+### Deprecated
+
+- All Pipecat services imports have been deprecated and a warning will be shown
+  when using the old import. The new import should be
+  `pipecat.services.[service].[image,llm,memory,stt,tts,video,vision]`. For
+  example, `from pipecat.services.openai.llm import OpenAILLMService`.
+
+- Import for AI services base classes from `pipecat.services.ai_services` is now
+  deprecated, use one of
+  `pipecat.services.[ai_service,image_service,llm_service,stt_service,vision_service]`.
+
+- Deprecated the `language` parameter in `GladiaSTTService.InputParams` in
+  favor of `language_config`, which better aligns with Gladia's API.
+
+- Deprecated using `GladiaSTTService.InputParams` directly. Use the new
+  `GladiaInputParams` class instead.
+
+### Fixed
+
+- Fixed a `FastAPIWebsocketTransport` and `WebsocketClientTransport` issue that
+  would cause the transport to be closed prematurely, preventing the internally
+  queued audio to be sent. The same issue could also cause an infinite loop
+  while using an output mixer and when sending an `EndFrame`, preventing the bot
+  to finish.
+
+- Fixed an issue that could cause the `TranscriptionUpdateFrame` being pushed
+  because of an interruption to be discarded.
+
+- Fixed an issue that would cause `SegmentedSTTService` based services
+  (e.g. `OpenAISTTService`) to try to transcribe non-spoken audio, causing
+  invalid transcriptions.
+
+- Fixed an issue where `GoogleTTSService` was emitting two `TTSStoppedFrames`.
+
+### Performance
+
+- Output transports now send 40ms audio chunks instead of 20ms. This should
+  improve performance.
+
+- `BotSpeakingFrame`s are now sent every 200ms. If the output transport audio chunks
+  are higher than 200ms then they will be sent at every audio chunk.
+
+### Other
+
+- Added foundational example `37-mem0.py` demonstrating how to use the
+  `Mem0MemoryService`.
+
+- Added foundational example `13e-whisper-mlx.py` demonstrating how to use the
+  `WhisperSTTServiceMLX`.
+
+## [0.0.61] - 2025-03-26
+
+### Added
+
+- Added a new frame, `LLMSetToolChoiceFrame`, which provides a mechanism
+  for modifying the `tool_choice` in the context.
+
+- Added `GroqTTSService` which provides text-to-speech functionality using
+  Groq's API.
+
+- Added support in `DailyTransport` for updating remote participants'
+  `canReceive` permission via the `update_remote_participants()` method, by
+  bumping the daily-python dependency to >= 0.16.0.
+
+- ElevenLabs TTS services now support a sample rate of 8000.
+
+- Added support for `instructions` in `OpenAITTSService`.
+
+- Added support for `base_url` in `OpenAIImageGenService` and
+  `OpenAITTSService`.
+
+### Fixed
+
+- Fixed an issue in `RTVIObserver` that prevented handling of Google LLM
+  context messages. The observer now processes both OpenAI-style and
+  Google-style contexts.
+
+- Fixed an issue in Daily involving switching virtual devices, by bumping the
+  daily-python dependency to >= 0.16.1.
+
+- Fixed a `GoogleAssistantContextAggregator` issue where function calls
+  placeholders where not being updated when then function call result was
+  different from a string.
+
+- Fixed an issue that would cause `LLMAssistantContextAggregator` to block
+  processing more frames while processing a function call result.
+
 - Fixed an issue where the `RTVIObserver` would report two bot started and
  stopped speaking events for each bot turn.

+
+- Class docstrings should fully document all parameters used in `__init__`
+- We don't require separate docstrings for `__init__` methods when parameters are documented in the class docstring
+- Property methods should have docstrings explaining their purpose and return value

+```python
+class MyClass:
+    """Class description.

+    Additional details about the class.
+
+    Args:
+        param1: Description of first parameter.

+# Handling PSTN/SIP Dial-in on Pipecat Cloud
+
+This repository contains two server implementations for handling
+the pinless dial-in workflow in Pipecat Cloud. This is the companion to the
+Pipecat Cloud [pstn_sip starter image](https://github.com/daily-co/pipecat-cloud-images/tree/main/pipecat-starters/pstn_sip).
+In addition you can use `/api/dial` to trigger dial-out, and
+eventually, call-transfers.
+
+1. [FastAPI Server](fastapi-webhook-server/README.md) -
+   A FastAPI implementation that handles PSTN (Public Switched Telephone
+   Network) and SIP (Session Initiation Protocol) calls using the Daily API.
+
+2. [Next.js Serverless](nextjs-webhook-server/README.md) -
+   A Next.js API implementation designed for deployment on Vercel's
+   serverless platform.
+
+Both implementations provide:
+
+- HMAC signature validation for pinless webhook
+- Structured logging
+- Support for dial-in and dial-out settings
+- Voicemail detection and call transfer functionality (coming soon)
+- Test request handling
+
+## Choosing an Implementation
+
+- Use the **FastAPI Server** if you:
+
+  - Need a standalone server
+  - Prefer Python and FastAPI
+  - Want to deploy to traditional hosting platforms
+
+- Use the **Next.js Serverless** implementation if you:
+  - Want serverless deployment
+  - Prefer JavaScript/TypeScript
+  - Already use Next.js and Vercel for other projects
+  - Need quick scaling and zero maintenance
+
+## Prerequisites
+
+### Environment Variables
+
+Both implementations require similar environment variables:
+
+- `PIPECAT_CLOUD_API_KEY`: Pipecat Cloud API Key, begins with pk\_\*
+- `AGENT_NAME`: Your Daily agent name
+- `PINLESS_HMAC_SECRET`: Your HMAC secret for request verification
+- `LOG_LEVEL`: (Optional) Logging level (defaults to 'info')
+
+See the individual README files in each implementation directory for
+specific setup instructions.
+
+### Phone number setup
+
+You can buy a phone number through the Pipecat Cloud Dashboard:
+
+1. Go to `Settings` > `Telephony`
+2. Follow the UI to purchase a phone number
+3. Configure the webhook URL to receive incoming calls (e.g. `https://my-webhook-url.com/api/dial`)
+
+Or purchase the number using Daily's
+[PhoneNumbers API](https://docs.daily.co/reference/rest-api/phone-numbers).
+
+```bash
+curl --request POST \
+--url https://api.daily.co/v1/domain-dialin-config \
+--header 'Authorization: Bearer $TOKEN' \
+--header 'Content-Type: application/json' \
+--data-raw '{
+	"type": "pinless_dialin",
+	"name_prefix": "Customer1",
+    "phone_number": "+1PURCHASED_NUM",
+	"room_creation_api": "https://example.com/api/dial",
+    "hold_music_url": "https://example.com/static/ringtone.mp3",
+	"timeout_config": {
+		"message": "No agent is available right now"
+	}
+}'
+```
+
+The API will return a static SIP URI (`sip_uri`) that can be called
+from other SIP services.
+
+### `room_creation_api`
+
+To make and receive calls currently you have to host a server that
+handles incoming calls. In the coming weeks, incoming calls will be
+directly handled within Daily and we will expose an endpoint similar
+to `{service}/start` that will manage this for you.
+
+In the meantime, the server described below serves as the webhook
+handler for the `room_creation_api`. Configure your pinless phone
+number or SIP interconnect to the `ngrok` tunnel or
+the actual server URL, append `/api/dial` to the webhook URL.
+
+## Example curl commands
+
+Note: Replace `http://localhost:3000` with your actual server URL and
+phone numbers with valid values for your use case.
+
+### Dialin Request
+
+The server will receive a request when a call is received from Daily.
+
+### Dialout Request
+
+Dial a number, will use any purchased number
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+      }
+    ]
+  }'
+```
+
+Dial a number with callerId, which is the UUID of a purchased number.
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+        "callerId": "purchased_phone_uuid"
+      }
+    ]
+  }'
+```
+
+Dial a number
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+        "callerId": "purchased_phone_uuid"
+      }
+    ]
+  }'
+```
+
+### Advanced Request with Voicemail Detection
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "To": "+1234567890",
+    "From": "+1987654321",
+    "callId": "call-uuid-123",
+    "callDomain": "domain-uuid-456",

+      {
+        "phoneNumber": "+1234567890",

+# FastAPI server for handling Daily PSTN/SIP Webhook
+
+A FastAPI server that handles PSTN (Public Switched Telephone Network) and SIP (Session Initiation Protocol) calls using the Daily API.
+
+## Setup
+
+1. Clone the repository
+
+2. Navigate to the `fastapi-webhook-server` directory:
+
+   ```bash
+   cd fastapi-webhook-server
+   ```
+
+3. Install dependencies:
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+4. Copy `env.example` to `.env`:
+
+   ```bash
+   cp env.example .env
+   ```
+
+5. Update `.env` with your credentials:
+
+   - `AGENT_NAME`: Your Daily agent name
+   - `PIPECAT_CLOUD_API_KEY`: Your Daily API key
+   - `PINLESS_HMAC_SECRET`: Your HMAC secret for request verification
+
+## Running the Server
+
+Start the server:
+
+```bash
+python server.py
+```
+
+The server will run on `http://localhost:7860` and you can expose it via ngrok for testing:
+
+```bash
+`ngrok http 7860`
+```
+
+> Tip: Use a subdomain for a consistent URL (e.g. `ngrok http -subdomain=mydomain http://localhost:7860`)
+
+## API Endpoints
+
+### GET /
+
+Health check endpoint that returns a "Hello, World!" message.
+
+### POST /api/dial
+
+Initiates a PSTN/SIP call with the following request body format:
+
+```json
+{
+  "To": "+14152251493",
+  "From": "+14158483432",
+  "callId": "string-contains-uuid",
+  "callDomain": "string-contains-uuid",
+  "dialout_settings": [
+    {
+      "phoneNumber": "+14158483432",
+      "callerId": "+14152251493"
+    }
+  ],
+  "voicemail_detection": {
+    "testInPrebuilt": true
+  },
+  "call_transfer": {
+    "mode": "dialout",
+    "speakSummary": true,
+    "storeSummary": true,
+    "operatorNumber": "+14152250006",
+    "testInPrebuilt": true
+  }
+}
+```
+
+#### Response
+
+Returns a JSON object containing:
+
+- `status`: Success/failure status
+- `data`: Response from Daily API
+- `room_properties`: Properties of the created Daily room
+
+## Error Handling
+
+- 401: Invalid signature
+- 400: Invalid authorization header (e.g. missing Daily API key in bot.py)
+- 405: Method not allowed (e.g. incorrect route on the webhook URL)
+- 500: Server errors (missing API key, network issues)
+- Other status codes are passed through from the Daily API

+   AGENT_NAME=my-first-agent
+   PINLESS_HMAC_SECRET=your_hmac_secret
+   LOG_LEVEL=info
+   ```
+
+### Running the server
+
+Run the development server:
+
+```bash
+npm run dev
+```
+
+The server will run on `http://localhost:7860` and you can expose it via ngrok for testing:
+
+```bash
+`ngrok http 7860`
+```
+
+> Tip: Use a subdomain for a consistent URL (e.g. `ngrok http -subdomain=mydomain http://localhost:7860`)
+
+## API Endpoints
+
+### GET /api
+
+Returns a simple "Hello, World!" message with a cute cat emoji to verify the server is running.
+
+### POST /api/dial
+
+Handles dial-in and dial-out requests for Pipecat Cloud.
+
+#### Test Requests
+
+The endpoint handles test requests when a webhook is configured. Send a request with `"Test": "test"` to verify your setup:
+
+```json
+{
+  "Test": "test"
+}
+```
+
+#### Production Request Format
+
+```json
+{
+  // for dial-in from webhook
+  "To": "+14152251493",
+  "From": "+14158483432",
+  "callId": "string-contains-uuid",
+  "callDomain": "string-contains-uuid",
+  // for making a dial out to a phone or SIP
+  "dialout_settings": [
+    { "phoneNumber": "+14158483432", "callerId": "purchased_phone_uuid" },
+    { "sipUri": "sip:username@sip.hostname.com" }
+  ]
+}
+```
+
+## Deployment
+
+The application is configured for Vercel deployment:
+
+1. Push your code to a Git repository
+2. Import your project in Vercel dashboard
+3. Configure environment variables:
+   - `PIPECAT_CLOUD_API_KEY`
+   - `AGENT_NAME`
+   - `PINLESS_HMAC_SECRET`
+   - `LOG_LEVEL` (optional, defaults to 'info')
+4. Deploy!
+
+## Security
+
+- HMAC signature validation for request authentication
+- Environment variables for sensitive credentials
+- Method validation (POST only for /dial)
