+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Other
+
+- Add missing dependencies in some of the examples.
+
+## [0.0.11] - 2024-05-13
+
+### Added
+
+- Allow stopping pipeline tasks with new `StopTaskFrame`.
+
+### Changed
+
+- TTS, STT and image generation service now use `AsyncGenerator`.
+
+### Fixed
+
+- `DailyTransport`: allow registering for participant transcriptions even if
+  input transport is not initialized yet.
+
+### Other
+
+- Updated `storytelling-chatbot`.
+
+## [0.0.10] - 2024-05-13
+
+### Added
+
+- Added Intel GPU support to `MoondreamService`.
+
+- Added support for sending transport messages (e.g. to communicate with an app
+  at the other end of the transport).
+
+- Added `FrameProcessor.push_error()` to easily send an `ErrorFrame` upstream.
+
+### Fixed
+
+- Fixed Azure services (TTS and image generation).
+
+### Other
+
+- Updated `simple-chatbot`, `moondream-chatbot` and `translation-chatbot`
+  examples.
+
+## [0.0.9] - 2024-05-12
+
+### Changed
+
+Many things have changed in this version. Many of the main ideas such as frames,
+processors, services and transports are still there but some things have changed
+a bit.
+
+- `Frame`s describe the basic units for processing. For example, text, image or
+  audio frames. Or control frames to indicate a user has started or stopped
+  speaking.
+
+- `FrameProcessor`s process frames (e.g. they convert a `TextFrame` to an
+  `ImageRawFrame`) and push new frames downstream or upstream to their linked
+  peers.
+
+- `FrameProcessor`s can be linked together. The easiest wait is to use the
+  `Pipeline` which is a container for processors. Linking processors allow
+  frames to travel upstream or downstream easily.
+
+- `Transport`s are a way to send or receive frames. There can be local
+  transports (e.g. local audio or native apps), network transports
+  (e.g. websocket) or service transports (e.g. https://daily.co).
+
+- `Pipeline`s are just a processor container for other processors.
+
+- A `PipelineTask` know how to run a pipeline.
+
+- A `PipelineRunner` can run one or more tasks and it is also used, for example,
+  to capture Ctrl-C from the user.
+
+## [0.0.8] - 2024-04-11
+
+### Added
+
+- Added `FireworksLLMService`.
+
+- Added `InterimTranscriptionFrame` and enable interim results in
+  `DailyTransport` transcriptions.
+
+### Changed
+
+- `FalImageGenService` now uses new `fal_client` package.
+
+### Fixed
+
+- `FalImageGenService`: use `asyncio.to_thread` to not block main loop when
+  generating images.
+
+- Allow `TranscriptionFrame` after an end frame (transcriptions can be delayed
+  and received after `UserStoppedSpeakingFrame`).
+
+## [0.0.7] - 2024-04-10
+
+### Added
+
+- Add `use_cpu` argument to `MoondreamService`.
+
+## [0.0.6] - 2024-04-10
+
+### Added
+
+- Added `FalImageGenService.InputParams`.
+
+- Added `URLImageFrame` and `UserImageFrame`.
+
+- Added `UserImageRequestFrame` and allow requesting an image from a participant.
+
+- Added base `VisionService` and `MoondreamService`
+
+### Changed
+
+- Don't pass `image_size` to `ImageGenService`, images should have their own size.
+
+- `ImageFrame` now receives a tuple`(width,height)` to specify the size.
+
+- `on_first_other_participant_joined` now gets a participant argument.
+
+### Fixed
+
+- Check if camera, speaker and microphone are enabled before writing to them.
+
+### Performance
+
+- `DailyTransport` only subscribe to desired participant video track.
+
+## [0.0.5] - 2024-04-06
+
+### Changed
+
+- Use `camera_bitrate` and `camera_framerate`.
+
+- Increase `camera_framerate` to 30 by default.
+
+### Fixed
+
+- Fixed `LocalTransport.read_audio_frames`.
+
+## [0.0.4] - 2024-04-04
+
+### Added
+
+- Added project optional dependencies [silero,openai,...].
+
+### Changed
+
+- Moved thransports to its own directory.
+
+- Use `OPENAI_API_KEY` instead of `OPENAI_CHATGPT_API_KEY`.
+
+### Fixed
+
+- Don't write to microphone/speaker if not enabled.
+
+### Other
+
+- Added live translation example.
+
+- Fix foundational examples.
+
+## [0.0.3] - 2024-03-13
+
+### Other
+
+- Added `storybot` and `chatbot` examples.
