@@ -9,6 +9,847 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
+- 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.
+
+- Fixed an issue in `UltravoxSTTService` that caused improper audio processing
+  and incorrect LLM frame output.
+
+### Other
+
+- Added `examples/foundational/07x-interruptible-local.py` to show how a local
+  transport can be used.
+
+## [0.0.60] - 2025-03-20
+
+### Added
+
+- Added `default_headers` parameter to `BaseOpenAILLMService` constructor.
+
+### Changed
+
+- Rollback to `deepgram-sdk` 3.8.0 since 3.10.1 was causing connections issues.
+
+- Changed the default `InputAudioTranscription` model to `gpt-4o-transcribe`
+  for `OpenAIRealtimeBetaLLMService`.
+
+### Other
+
+- Update the `19-openai-realtime-beta.py` and `19a-azure-realtime-beta.py`
+  examples to use the FunctionSchema format.
+
+## [0.0.59] - 2025-03-20
+
+### Added
+
+- When registering a function call it is now possible to indicate if you want
+  the function call to be cancelled if there's a user interruption via
+  `cancel_on_interruption` (defaults to False). This is now possible because
+  function calls are executed concurrently.
+
+- Added support for detecting idle pipelines. By default, if no activity has
+  been detected during 5 minutes, the `PipelineTask` will be automatically
+  cancelled. It is possible to override this behavior by passing
+  `cancel_on_idle_timeout=False`. It is also possible to change the default
+  timeout with `idle_timeout_secs` or the frames that prevent the pipeline from
+  being idle with `idle_timeout_frames`. Finally, an `on_idle_timeout` event
+  handler will be triggered if the idle timeout is reached (whether the pipeline
+  task is cancelled or not).
+
+- Added `FalSTTService`, which provides STT for Fal's Wizper API.
+
+- Added a `reconnect_on_error` parameter to websocket-based TTS services as well
+  as a `on_connection_error` event handler. The `reconnect_on_error` indicates
+  whether the TTS service should reconnect on error. The `on_connection_error`
+  will always get called if there's any error no matter the value of
+  `reconnect_on_error`. This allows, for example, to fallback to a different TTS
+  provider if something goes wrong with the current one.
+
+- Added new `SkipTagsAggregator` that extends `BaseTextAggregator` to aggregate
+  text and skips end of sentence matching if aggregated text is between
+  start/end tags.
+
+- Added new `PatternPairAggregator` that extends `BaseTextAggregator` to
+  identify content between matching pattern pairs in streamed text. This allows
+  for detection and processing of structured content like XML-style tags that
+  may span across multiple text chunks or sentence boundaries.
+
+- Added new `BaseTextAggregator`. Text aggregators are used by the TTS service
+  to aggregate LLM tokens and decide when the aggregated text should be pushed
+  to the TTS service. They also allow for the text to be manipulated while it's
+  being aggregated. A text aggregator can be passed via `text_aggregator` to the
+  TTS service.
+
+- Added new `sample_rate` constructor parameter to `TavusVideoService` to allow
+  changing the output sample rate.
+
+- Added new `NeuphonicTTSService`.
+  (see https://neuphonic.com)
+
+- Added new `UltravoxSTTService`.
+  (see https://github.com/fixie-ai/ultravox)
+
+- Added `on_frame_reached_upstream` and `on_frame_reached_downstream` event
+  handlers to `PipelineTask`. Those events will be called when a frame reaches
+  the beginning or end of the pipeline respectively. Note that by default, the
+  event handlers will not be called unless a filter is set with
+  `PipelineTask.set_reached_upstream_filter()` or
+  `PipelineTask.set_reached_downstream_filter()`.
+
+- Added support for Chirp voices in `GoogleTTSService`.
+
+- Added a `flush_audio()` method to `FishTTSService` and `LmntTTSService`.
+
+- Added a `set_language` convenience method for `GoogleSTTService`, allowing
+  you to set a single language. This is in addition to the `set_languages`
+  method which allows you to set a list of languages.
+
+- Added `on_user_turn_audio_data` and `on_bot_turn_audio_data` to
+  `AudioBufferProcessor`. This gives the ability to grab the audio of only that
+  turn for both the user and the bot.
+
+- Added new base class `BaseObject` which is now the base class of
+  `FrameProcessor`, `PipelineRunner`, `PipelineTask` and `BaseTransport`. The
+  new `BaseObject` adds supports for event handlers.
+
+- Added support for a unified format for specifying function calling across all
+  LLM services.
+
+```python
+  weather_function = FunctionSchema(
+      name="get_current_weather",
+      description="Get the current weather",
+      properties={
+          "location": {
+              "type": "string",
+              "description": "The city and state, e.g. San Francisco, CA",
+          },
+          "format": {
+              "type": "string",
+              "enum": ["celsius", "fahrenheit"],
+              "description": "The temperature unit to use. Infer this from the user's location.",
+          },
+      },
+      required=["location"],
+  )
+  tools = ToolsSchema(standard_tools=[weather_function])
+```
+
+- Added `speech_threshold` parameter to `GladiaSTTService`.
+
+- Allow passing user (`user_kwargs`) and assistant (`assistant_kwargs`) context
+  aggregator parameters when using `create_context_aggregator()`. The values are
+  passed as a mapping that will then be converted to arguments.
+
+- Added `speed` as an `InputParam` for both `ElevenLabsTTSService` and
+  `ElevenLabsHttpTTSService`.
+
+- Added new `LLMFullResponseAggregator` to aggregate full LLM completions. At
+  every completion the `on_completion` event handler is triggered.
+
+- Added a new frame, `RTVIServerMessageFrame`, and RTVI message
+  `RTVIServerMessage` which provides a generic mechanism for sending custom
+  messages from server to client. The `RTVIServerMessageFrame` is processed by
+  the `RTVIObserver` and will be delivered to the client's `onServerMessage`
+  callback or `ServerMessage` event.
+
+- Added `GoogleLLMOpenAIBetaService` for Google LLM integration with an
+  OpenAI-compatible interface. Added foundational example
+  `14o-function-calling-gemini-openai-format.py`.
+
+- Added `AzureRealtimeBetaLLMService` to support Azure's OpeanAI Realtime API. Added
+  foundational example `19a-azure-realtime-beta.py`.
+
+- Introduced `GoogleVertexLLMService`, a new class for integrating with Vertex AI
+  Gemini models. Added foundational example
+  `14p-function-calling-gemini-vertex-ai.py`.
+
+- Added support in `OpenAIRealtimeBetaLLMService` for a slate of new features:
+
+  - The `'gpt-4o-transcribe'` input audio transcription model, along
+    with new `language` and `prompt` options specific to that model.
+  - The `input_audio_noise_reduction` session property.
+
+    ```python
+    session_properties = SessionProperties(
+      # ...
+      input_audio_noise_reduction=InputAudioNoiseReduction(
+        type="near_field" # also supported: "far_field"
+      )
+      # ...
+    )
+    ```
+
+  - The `'semantic_vad'` `turn_detection` session property value, a more
+    sophisticated model for detecting when the user has stopped speaking.
+  - `on_conversation_item_created` and `on_conversation_item_updated`
+    events to `OpenAIRealtimeBetaLLMService`.
+
+    ```python
+    @llm.event_handler("on_conversation_item_created")
+    async def on_conversation_item_created(llm, item_id, item):
+      # ...
+
+    @llm.event_handler("on_conversation_item_updated")
+    async def on_conversation_item_updated(llm, item_id, item):
+      # `item` may not always be available here
+      # ...
+    ```
+
+  - The `retrieve_conversation_item(item_id)` method for introspecting a
+    conversation item on the server.
+
+    ```python
+    item = await llm.retrieve_conversation_item(item_id)
+    ```
+
+### Changed
+
+- Updated `OpenAISTTService` to use `gpt-4o-transcribe` as the default
+  transcription model.
+
+- Updated `OpenAITTSService` to use `gpt-4o-mini-tts` as the default TTS model.
+
+- Function calls are now executed in tasks. This means that the pipeline will
+  not be blocked while the function call is being executed.
+
+- ⚠️ `PipelineTask` will now be automatically cancelled if no bot activity is
+  happening in the pipeline. There are a few settings to configure this
+  behavior, see `PipelineTask` documentation for more details.
+
+- All event handlers are now executed in separate tasks in order to prevent
+  blocking the pipeline. It is possible that event handlers take some time to
+  execute in which case the pipeline would be blocked waiting for the event
+  handler to complete.
+
+- Updated `TranscriptProcessor` to support text output from
+  `OpenAIRealtimeBetaLLMService`.
+
+- `OpenAIRealtimeBetaLLMService` and `GeminiMultimodalLiveLLMService` now push
+  a `TTSTextFrame`.
+
+- Updated the default mode for `CartesiaTTSService` and
+  `CartesiaHttpTTSService` to `sonic-2`.
+
+### Deprecated
+
+- Passing a `start_callback` to `LLMService.register_function()` is now
+  deprecated, simply move the code from the start callback to the function call.
+
+- `TTSService` parameter `text_filter` is now deprecated, use `text_filters`
+  instead which is now a list. This allows passing multiple filters that will be
+  executed in order.
+
+### Removed
+
+- Removed deprecated `audio.resample_audio()`, use `create_default_resampler()`
+  instead.
+
+- Removed deprecated`stt_service` parameter from `STTMuteFilter`.
+
+- Removed deprecated RTVI processors, use an `RTVIObserver` instead.
+
+- Removed deprecated `AWSTTSService`, use `PollyTTSService` instead.
+
+- Removed deprecated field `tier` from `DailyTranscriptionSettings`, use `model`
+  instead.
+
+- Removed deprecated `pipecat.vad` package, use `pipecat.audio.vad` instead.
+
+### Fixed
+
+- Fixed an assistant aggregator issue that could cause assistant text to be
+  split into multiple chunks during function calls.
+
+- Fixed an assistant aggregator issue that was causing assistant text to not be
+  added to the context during function calls. This could lead to duplications.
+
+- Fixed a `SegmentedSTTService` issue that was causing audio to be sent
+  prematurely to the STT service. Instead of analyzing the volume in this
+  service we rely on VAD events which use both VAD and volume.
+
+- Fixed a `GeminiMultimodalLiveLLMService` issue that was causing messages to be
+  duplicated in the context when pushing `LLMMessagesAppendFrame` frames.
+
+- Fixed an issue with `SegmentedSTTService` based services
+  (e.g. `GroqSTTService`) that was not allow audio to pass-through downstream.
+
+- Fixed a `CartesiaTTSService` and `RimeTTSService` issue that would consider
+  text between spelling out tags end of sentence.
+
+- Fixed a `match_endofsentence` issue that would result in floating point
+  numbers to be considered an end of sentence.
+
+- Fixed a `match_endofsentence` issue that would result in emails to be
+  considered an end of sentence.
+
+- Fixed an issue where the RTVI message `disconnect-bot` was pushing an
+  `EndFrame`, resulting in the pipeline not shutting down. It now pushes an
+  `EndTaskFrame` upstream to shutdown the pipeline.
+
+- Fixed an issue with the `GoogleSTTService` where stream timeouts during
+  periods of inactivity were causing connection failures. The service now
+  properly detects timeout errors and handles reconnection gracefully,
+  ensuring continuous operation even after periods of silence or when using an
+  `STTMuteFilter`.
+
+- Fixed an issue in `RimeTTSService` where the last line of text sent didn't
+  result in an audio output being generated.
+
+- Fixed `OpenAIRealtimeBetaLLMService` by adding proper handling for:
+  - The `conversation.item.input_audio_transcription.delta` server message,
+    which was added server-side at some point and not handled client-side.
+  - Errors reported by the `response.done` server message.
+
+### Other
+
+- Add foundational example `07w-interruptible-fal.py`, showing `FalSTTService`.
+
+- Added a new Ultravox example
+  `examples/foundational/07u-interruptible-ultravox.py`.
+
+- Added new Neuphonic examples
+  `examples/foundational/07v-interruptible-neuphonic.py` and
+  `examples/foundational/07v-interruptible-neuphonic-http.py`.
+
+- Added a new example `examples/foundational/36-user-email-gathering.py` to show
+  how to gather user emails. The example uses's Cartesia's `<spell></spell>`
+  tags and Rime `spell()` function to spell out the emails for confirmation.
+
+- Update the `34-audio-recording.py` example to include an STT processor.
+
+- Added foundational example `35-voice-switching.py` showing how to use the new
+  `PatternPairAggregator`. This example shows how to encode information for the
+  LLM to instruct TTS voice changes, but this can be used to encode any
+  information into the LLM response, which you want to parse and use in other
+  parts of your application.
+
+- Added a Pipecat Cloud deployment example to the `examples` directory.
+
+- Removed foundational examples 28b and 28c as the TranscriptProcessor no
+  longer has an LLM depedency. Renamed foundational example 28a to
+  `28-transcript-processor.py`.
+
+## [0.0.58] - 2025-02-26
+
+### Added
+
+- Added track-specific audio event `on_track_audio_data` to
+  `AudioBufferProcessor` for accessing separate input and output audio tracks.
+
+- Pipecat version will now be logged on every application startup. This will
+  help us identify what version we are running in case of any issues.
+
+- Added a new `StopFrame` which can be used to stop a pipeline task while
+  keeping the frame processors running. The frame processors could then be used
+  in a different pipeline. The difference between a `StopFrame` and a
+  `StopTaskFrame` is that, as with `EndFrame` and `EndTaskFrame`, the
+  `StopFrame` is pushed from the task and the `StopTaskFrame` is pushed upstream
+  inside the pipeline by any processor.
+
+- Added a new `PipelineTask` parameter `observers` that replaces the previous
+  `PipelineParams.observers`.
+
+- Added a new `PipelineTask` parameter `check_dangling_tasks` to enable or
+  disable checking for frame processors' dangling tasks when the Pipeline
+  finishes running.
+
+- Added new `on_completion_timeout` event for LLM services (all OpenAI-based
+  services, Anthropic and Google). Note that this event will only get triggered
+  if LLM timeouts are setup and if the timeout was reached. It can be useful to
+  retrigger another completion and see if the timeout was just a blip.
+
+- Added new log observers `LLMLogObserver` and `TranscriptionLogObserver` that
+  can be useful for debugging your pipelines.
+
+- Added `room_url` property to `DailyTransport`.
+
+- Added `addons` argument to `DeepgramSTTService`.
+
+- Added `exponential_backoff_time()` to `utils.network` module.
+
+### Changed
+
+- ⚠️ `PipelineTask` now requires keyword arguments (except for the first one for
+  the pipeline).
+
+- Updated `PlayHTHttpTTSService` to take a `voice_engine` and `protocol` input
+  in the constructor. The previous method of providing a `voice_engine` input
+  that contains the engine and protocol is deprecated by PlayHT.
+
+- The base `TTSService` class now strips leading newlines before sending text
+  to the TTS provider. This change is to solve issues where some TTS providers,
+  like Azure, would not output text due to newlines.
+
+- `GrokLLMSService` now uses `grok-2` as the default model.
+
+- `AnthropicLLMService` now uses `claude-3-7-sonnet-20250219` as the default
+  model.
+
+- `RimeHttpTTSService` needs an `aiohttp.ClientSession` to be passed to the
+  constructor as all the other HTTP-based services.
+
+- `RimeHttpTTSService` doesn't use a default voice anymore.
+
+- `DeepgramSTTService` now uses the new `nova-3` model by default. If you want
+  to use the previous model you can pass `LiveOptions(model="nova-2-general")`.
+  (see https://deepgram.com/learn/introducing-nova-3-speech-to-text-api)
+
+```python
+stt = DeepgramSTTService(..., live_options=LiveOptions(model="nova-2-general"))
+```
+
+### Deprecated
+
+- `PipelineParams.observers` is now deprecated, you the new `PipelineTask`
+  parameter `observers`.
+
+### Removed
+
+- Remove `TransportParams.audio_out_is_live` since it was not being used at all.
+
+### Fixed
+
+- Fixed an issue that would cause undesired interruptions via
+  `EmulateUserStartedSpeakingFrame`.
+
+- Fixed a `GoogleLLMService` that was causing an exception when sending inline
+  audio in some cases.
+
+- Fixed an `AudioContextWordTTSService` issue that would cause an `EndFrame` to
+  disconnect from the TTS service before audio from all the contexts was
+  received. This affected services like Cartesia and Rime.
+
+- Fixed an issue that was not allowing to pass an `OpenAILLMContext` to create
+  `GoogleLLMService`'s context aggregators.
+
+- Fixed a `ElevenLabsTTSService`, `FishAudioTTSService`, `LMNTTTSService` and
+  `PlayHTTTSService` issue that was resulting in audio requested before an
+  interruption being played after an interruption.
+
+- Fixed `match_endofsentence` support for ellipses.
+
+- Fixed an issue where `EndTaskFrame` was not triggering
+  `on_client_disconnected` or closing the WebSocket in FastAPI.
+
+- Fixed an issue in `DeepgramSTTService` where the `sample_rate` passed to the
+  `LiveOptions` was not being used, causing the service to use the default
+  sample rate of pipeline.
+
+- Fixed a context aggregator issue that would not append the LLM text response
+  to the context if a function call happened in the same LLM turn.
+
+- Fixed an issue that was causing HTTP TTS services to push `TTSStoppedFrame`
+  more than once.
+
+- Fixed a `FishAudioTTSService` issue where `TTSStoppedFrame` was not being
+  pushed.
+
+- Fixed an issue that `start_callback` was not invoked for some LLM services.
+
+- Fixed an issue that would cause `DeepgramSTTService` to stop working after an
+  error occurred (e.g. sudden network loss). If the network recovered we would
+  not reconnect.
+
+- Fixed a `STTMuteFilter` issue that would not mute user audio frames causing
+  transcriptions to be generated by the STT service.
+
+### Other
+
+- Added Gemini support to `examples/phone-chatbot`.
+
+- Added foundational example `34-audio-recording.py` showing how to use the
+  AudioBufferProcessor callbacks to save merged and track recordings.
+
+## [0.0.57] - 2025-02-14
+
+### Added
+
+- Added new `AudioContextWordTTSService`. This is a TTS base class for TTS
+  services that handling multiple separate audio requests.
+
+- Added new frames `EmulateUserStartedSpeakingFrame` and
+  `EmulateUserStoppedSpeakingFrame` which can be used to emulated VAD behavior
+  without VAD being present or not being triggered.
+
+- Added a new `audio_in_stream_on_start` field to `TransportParams`.
+
+- Added a new method `start_audio_in_streaming` in the `BaseInputTransport`.
+
+  - This method should be used to start receiving the input audio in case the
+    field `audio_in_stream_on_start` is set to `false`.
+
+- Added support for the `RTVIProcessor` to handle buffered audio in `base64`
+  format, converting it into InputAudioRawFrame for transport.
+
+- Added support for the `RTVIProcessor` to trigger `start_audio_in_streaming`
+  only after the `client-ready` message.
+
+- Added new `MUTE_UNTIL_FIRST_BOT_COMPLETE` strategy to `STTMuteStrategy`. This
+  strategy starts muted and remains muted until the first bot speech completes,
+  ensuring the bot's first response cannot be interrupted. This complements the
+  existing `FIRST_SPEECH` strategy which only mutes during the first detected
+  bot speech.
+
+- Added support for Google Cloud Speech-to-Text V2 through `GoogleSTTService`.
+
+- Added `RimeTTSService`, a new `WordTTSService`. Updated the foundational
+  example `07q-interruptible-rime.py` to use `RimeTTSService`.
+
+- Added support for Groq's Whisper API through the new `GroqSTTService` and
+  OpenAI's Whisper API through the new `OpenAISTTService`. Introduced a new
+  base class `BaseWhisperSTTService` to handle common Whisper API
+  functionality.
+
+- Added `PerplexityLLMService` for Perplexity NIM API integration, with an
+  OpenAI-compatible interface. Also, added foundational example
+  `14n-function-calling-perplexity.py`.
+
+- Added `DailyTransport.update_remote_participants()`. This allows you to update
+  remote participant's settings, like their permissions or which of their
+  devices are enabled. Requires that the local participant have participant
+  admin permission.
+
+### Changed
+
+- We don't consider a colon `:` and end of sentence any more.
+
+- Updated `DailyTransport` to respect the `audio_in_stream_on_start` field,
+  ensuring it only starts receiving the audio input if it is enabled.
+
+- Updated `FastAPIWebsocketOutputTransport` to send `TransportMessageFrame` and
+  `TransportMessageUrgentFrame` to the serializer.
+
+- Updated `WebsocketServerOutputTransport` to send `TransportMessageFrame` and
+  `TransportMessageUrgentFrame` to the serializer.
+
+- Enhanced `STTMuteConfig` to validate strategy combinations, preventing
+  `MUTE_UNTIL_FIRST_BOT_COMPLETE` and `FIRST_SPEECH` from being used together
+  as they handle first bot speech differently.
+
+- Updated foundational example `07n-interruptible-google.py` to use all Google
+  services.
+
+- `RimeHttpTTSService` now uses the `mistv2` model by default.
+
+- Improved error handling in `AzureTTSService` to properly detect and log
+  synthesis cancellation errors.
+
+- Enhanced `WhisperSTTService` with full language support and improved model
+  documentation.
+
+- Updated foundation example `14f-function-calling-groq.py` to use
+  `GroqSTTService` for transcription.
+
+- Updated `GroqLLMService` to use `llama-3.3-70b-versatile` as the default
+  model.
+
+- `RTVIObserver` doesn't handle `LLMSearchResponseFrame` frames anymore. For
+  now, to handle those frames you need to create a `GoogleRTVIObserver`
+  instead.
+
+### Deprecated
+
+- `STTMuteFilter` constructor's `stt_service` parameter is now deprecated and
+  will be removed in a future version. The filter now manages mute state
+  internally instead of querying the STT service.
+
+- `RTVI.observer()` is now deprecated, instantiate an `RTVIObserver` directly
+  instead.
+
+- All RTVI frame processors (e.g. `RTVISpeakingProcessor`,
+  `RTVIBotLLMProcessor`) are now deprecated, instantiate an `RTVIObserver`
+  instead.
+
+### Fixed
+
+- Fixed a `FalImageGenService` issue that was causing the event loop to be
+  blocked while loading the downloadded image.
+
+- Fixed a `CartesiaTTSService` service issue that would cause audio overlapping
+  in some cases.
+
+- Fixed a websocket-based service issue (e.g. `CartesiaTTSService`) that was
+  preventing a reconnection after the server disconnected cleanly, which was
+  causing an inifite loop instead.
+
+- Fixed a `BaseOutputTransport` issue that was causing upstream frames to no be
+  pushed upstream.
+
+- Fixed multiple issue where user transcriptions where not being handled
+  properly. It was possible for short utterances to not trigger VAD which would
+  cause user transcriptions to be ignored. It was also possible for one or more
+  transcriptions to be generated after VAD in which case they would also be
+  ignored.
+
+- Fixed an issue that was causing `BotStoppedSpeakingFrame` to be generated too
+  late. This could then cause issues unblocking `STTMuteFilter` later than
+  desired.
+
+- Fixed an issue that was causing `AudioBufferProcessor` to not record
+  synchronized audio.
+
+- Fixed an `RTVI` issue that was causing `bot-tts-text` messages to be sent
+  before being processed by the output transport.
+
+- Fixed an issue[#1192] in 11labs where we are trying to reconnect/disconnect
+  the websocket connection even when the connection is already closed.
+
+- Fixed an issue where `has_regular_messages` condition was always true in
+  `GoogleLLMContext` due to `Part` having `function_call` & `function_response`
+  with `None` values.
+
+### Other
+
+- Added new `instant-voice` example. This example showcases how to enable
+  instant voice communication as soon as a user connects.
+
+- Added new `local-input-select-stt` example. This examples allows you to play
+  with local audio inputs by slecting them through a nice text interface.
+
+## [0.0.56] - 2025-02-06
+
+### Changed
+
+- Use `gemini-2.0-flash-001` as the default model for `GoogleLLMSerivce`.
+
+- Improved foundational examples 22b, 22c, and 22d to support function calling.
+  With these base examples, `FunctionCallInProgressFrame` and
+  `FunctionCallResultFrame` will no longer be blocked by the gates.
+
+### Fixed
+
+- Fixed a `TkLocalTransport` and `LocalAudioTransport` issues that was causing
+  errors on cleanup.
+
+- Fixed an issue that was causing `tests.utils` import to fail because of
+  logging setup.
+
+- Fixed a `SentryMetrics` issue that was preventing any metrics to be sent to
+  Sentry and also was preventing from metrics frames to be pushed to the
+  pipeline.
+
+- Fixed an issue in `BaseOutputTransport` where incoming audio would not be
+  resampled to the desired output sample rate.
+
+- Fixed an issue with the `TwilioFrameSerializer` and `TelnyxFrameSerializer`
+  where `twilio_sample_rate` and `telnyx_sample_rate` were incorrectly
+  initialized to `audio_in_sample_rate`. Those values currently default to 8000
+  and should be set manually from the serializer constructor if a different
+  value is needed.
+
+### Other
+
+- Added a new `sentry-metrics` example.
+
+## [0.0.55] - 2025-02-05
+
+### Added
+
+- Added a new `start_metadata` field to `PipelineParams`. The provided metadata
+  will be set to the initial `StartFrame` being pushed from the `PipelineTask`.
+
+- Added new fields to `PipelineParams` to control audio input and output sample
+  rates for the whole pipeline. This allows controlling sample rates from a
+  single place instead of having to specify sample rates in each
+  service. Setting a sample rate to a service is still possible and will
+  override the value from `PipelineParams`.
+
+- Introduce audio resamplers (`BaseAudioResampler`). This is just a base class
+  to implement audio resamplers. Currently, two implementations are provided
+  `SOXRAudioResampler` and `ResampyResampler`. A new
+  `create_default_resampler()` has been added (replacing the now deprecated
+  `resample_audio()`).
+
 - It is now possible to specify the asyncio event loop that a `PipelineTask` and
   all the processors should run on by passing it as a new argument to the
   `PipelineRunner`. This could allow running pipelines in multiple threads each

 ### Other
 
-- Updated all examples to use `task.cancel()` instead of pushing an `EndFrame`
-  when a participant leaves/disconnects. If you push an `EndFrame` this will
-  cause the bot to run through everything that is internally queued (which could
-  take seconds). Instead, if a participant disconnects there is nothing else to
-  be sent and therefore we should stop immediately.
+- Improved Unit Test `run_test()` to use `PipelineTask` and

+  `EndFrame`. The `EndTaskFrame` has been removed since it doesn't seem
+  necessary with this new approach.
+
+- Updated `twilio-chatbot` with a few new features: use 8000 sample rate and
+  avoid resampling, a new client useful for stress testing and testing locally
+  without the need to make phone calls. Also, added audio recording on both the

+# React Native Implementation
+
+Basic implementation using the [Pipecat React Native SDK](https://docs.pipecat.ai/client/react-native/introduction).
+
+## Usage
+
+### Expo requirements
+
+This project cannot be used with an [Expo Go](https://docs.expo.dev/workflow/expo-go/) app because [it requires custom native code](https://docs.expo.io/workflow/customizing/).
+
+When a project requires custom native code or a config plugin, we need to transition from using [Expo Go](https://docs.expo.dev/workflow/expo-go/) 
+to a [development build](https://docs.expo.dev/development/introduction/).
+
+More details about the custom native code used by this demo can be found in [rn-daily-js-expo-config-plugin](https://github.com/daily-co/rn-daily-js-expo-config-plugin).
+
+### Building remotely
+
+If you do not have experience with Xcode and Android Studio builds or do not have them installed locally on your computer, you will need to follow [this guide from Expo to use EAS Build](https://docs.expo.dev/development/create-development-builds/#create-and-install-eas-build).
+
+### Building locally
+
+You will need to have installed locally on your computer:
+- [Xcode](https://developer.apple.com/xcode/) to build for iOS;
+- [Android Studio](https://developer.android.com/studio) to build for Android;
+
+#### Install the demo dependencies
+
+```bash
+# Use the version of node specified in .nvmrc
+nvm i
+
+# Install dependencies
+npm i
+
+# Before a native app can be compiled, the native source code must be generated.
+npx expo prebuild
+
+# Configure the environment variable to connect to the local server
+cp env.example .env
+# edit .env and add your local ip address, for example: http://192.168.1.16:7860
+```
+
+#### Running on Android
+
+After plugging in an Android device [configured for debugging](https://developer.android.com/studio/debug/dev-options), run the following command:
+
+```
+npm run android
+```
+
+#### Running on iOS
+
+Run the following command:
+
+```
+npm run ios
+```
+
+#### Connect to the server
+Use the http://localhost:5173 in your app.

+# 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",

+# Next.js server for handling Daily PSTN/SIP Webhook
+
+Next.js API routes for handling Daily PSTN/SIP Pipecat requests.
+
+## Features
+
+- API endpoint for handling Daily PSTN/SIP Pipecat requests
+- HMAC signature validation
+- Structured logging with Pino
+- Support for dial-in and dial-out settings
+- Voicemail detection and call transfer functionality
+- Test request handling
+
+## Setup
+
+1. Clone the repository
+
+2. Navigate to the `nextjs-webhook-server` directory:
+
+   ```bash
+   cd nextjs-webhook-server
+   ```
+
+3. Install dependencies:
+
+   ```bash
+   npm install
+   ```
+
+4. Create `.env.local` file with your credentials:
+
+   ```bash
+   cp env.local.example .env.local
+   ```
+
+5. Update your `.env` with your secrets:
+
+   ```bash
+   PIPECAT_CLOUD_API_KEY=pk_*
+   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)

+# Pipecat Cloud Starter Project
+
+[![Docs](https://img.shields.io/badge/Documentation-blue)](https://docs.pipecat.daily.co) [![Discord](https://img.shields.io/discord/1217145424381743145)](https://discord.gg/dailyco)
+
+A template voice agent for [Pipecat Cloud](https://www.daily.co/products/pipecat-cloud/) that demonstrates building and deploying a conversational AI agent.
+
+> **For a detailed step-by-step guide, see our [Quickstart Documentation](https://docs.pipecat.daily.co/quickstart).**
+
+## Prerequisites
+
+- Python 3.10+
+- Linux, MacOS, or Windows Subsystem for Linux (WSL)
+- [Docker](https://www.docker.com) and a Docker repository (e.g., [Docker Hub](https://hub.docker.com))
+- A Docker Hub account (or other container registry account)
+- [Pipecat Cloud](https://pipecat.daily.co) account
+
+> **Note**: If you haven't installed Docker yet, follow the official installation guides for your platform ([Linux](https://docs.docker.com/engine/install/), [Mac](https://docs.docker.com/desktop/setup/install/mac-install/), [Windows](https://docs.docker.com/desktop/setup/install/windows-install/)). For Docker Hub, [create a free account](https://hub.docker.com/signup) and log in via terminal with `docker login`.
+
+## Get Started
+
+### 1. Get the starter project
+
+Clone the starter project from GitHub:
+
+```bash
+git clone https://github.com/daily-co/pipecat-cloud-starter
+cd pipecat-cloud-starter
+```
+
+### 2. Set up your Python environment
+
+We recommend using a virtual environment to manage your Python dependencies.
+
+```bash
+# Create a virtual environment
+python -m venv .venv
+
+# Activate it
+source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+
+# Install the Pipecat Cloud CLI
+pip install pipecatcloud
+```
+
+### 3. Authenticate with Pipecat Cloud
+
+```bash
+pcc auth login
+```
+
+### 4. Acquire required API keys
+
+This starter requires the following API keys:
+
+- **OpenAI API Key**: Get from [platform.openai.com/api-keys](https://platform.openai.com/api-keys)
+- **Cartesia API Key**: Get from [play.cartesia.ai/keys](https://play.cartesia.ai/keys)
+- **Daily API Key**: Automatically provided through your Pipecat Cloud account
+
+### 5. Configure to run locally (optional)
+
+You can test your agent locally before deploying to Pipecat Cloud:
+
+```bash
+# Set environment variables with your API keys
+export CARTESIA_API_KEY="your_cartesia_key"
+export DAILY_API_KEY="your_daily_key"
+export OPENAI_API_KEY="your_openai_key"
+```
+
+> Your `DAILY_API_KEY` can be found at [https://pipecat.daily.co](https://pipecat.daily.co) under the `Settings` in the `Daily (WebRTC)` tab.
+
+First install requirements:
+
+```bash
+pip install -r requirements.txt
+```
+
+Then, launch the bot.py script locally:
+
+```bash
+LOCAL_RUN=1 python bot.py
+```
+
+## Deploy & Run
+
+### 1. Build and push your Docker image
+
+```bash
+# Build the image (targeting ARM architecture for cloud deployment)
+docker build --platform=linux/arm64 -t my-first-agent:latest .
+
+# Tag with your Docker username and version
+docker tag my-first-agent:latest your-username/my-first-agent:0.1
+
+# Push to Docker Hub
+docker push your-username/my-first-agent:0.1
+```
+
+### 2. Create a secret set for your API keys
+
+The starter project requires API keys for OpenAI and Cartesia:
+
+```bash
+# Copy the example env file
+cp env.example .env
+
+# Edit .env to add your API keys:
+# CARTESIA_API_KEY=your_cartesia_key
+# OPENAI_API_KEY=your_openai_key
+
+# Create a secret set from your .env file
+pcc secrets set my-first-agent-secrets --file .env
+```
+
+Alternatively, you can create secrets directly via CLI:
+
+```bash
+pcc secrets set my-first-agent-secrets \
+  CARTESIA_API_KEY=your_cartesia_key \
+  OPENAI_API_KEY=your_openai_key
+```
+
+### 3. Deploy to Pipecat Cloud
+
+```bash
+pcc deploy my-first-agent your-username/my-first-agent:0.1 --secrets my-first-agent-secrets
+```
+
+> **Note (Optional)**: For a more maintainable approach, you can use the included `pcc-deploy.toml` file:
+>
+> ```toml
+> agent_name = "my-first-agent"
+> image = "your-username/my-first-agent:0.1"
+> secret_set = "my-first-agent-secrets"
+>
+> [scaling]
+>     min_instances = 0
+> ```
+>
+> Then simply run `pcc deploy` without additional arguments.
+
+> **Note**: If your repository is private, you'll need to add credentials:
+>
+> ```bash
+> # Create pull secret (you’ll be prompted for credentials)
+> pcc secrets image-pull-secret pull-secret https://index.docker.io/v1/
+>
+> # Deploy with credentials
+> pcc deploy my-first-agent your-username/my-first-agent:0.1 --credentials pull-secret
+> ```
+
+### 4. Check deployment and scaling (optional)
+
+By default, your agent will use "scale-to-zero" configuration, which means it may have a cold start of around 10 seconds when first used. By default, idle instances are maintained for 5 minutes before being terminated when using scale-to-zero.
+
+For more responsive testing, you can scale your deployment to keep a minimum of one instance warm:
+
+```bash
+# Ensure at least one warm instance is always available
+pcc deploy my-first-agent your-username/my-first-agent:0.1 --min-instances 1
+
+# Check the status of your deployment
+pcc agent status my-first-agent
+```
+
+By default, idle instances are maintained for 5 minutes before being terminated when using scale-to-zero.
+
+### 5. Create an API key
+
+```bash
+# Create a public API key for accessing your agent
+pcc organizations keys create
+
+# Set it as the default key to use with your agent
+pcc organizations keys use
+```
+
+### 6. Start your agent
+
+```bash
+# Start a session with your agent in a Daily room
+pcc agent start my-first-agent --use-daily
+```
+
+This will return a URL, which you can use to connect to your running agent.
