+## [Unreleased]
+
+### Added
+
+- Added video streaming support to `LiveKitTransport`.
+
+- Added `OpenAIRealtimeLLMService` and `AzureRealtimeLLMService` which provide
+  access to OpenAI Realtime.
+
+### Removed
+
+- Remove `VisionImageRawFrame` in favor of context frames (`LLMContextFrame` or
+  `OpenAILLMContextFrame`).
+
+### Deprecated
+
+- Deprecate `VisionImageFrameAggregator` because `VisionImageRawFrame` has been
+  removed. See the `12*` examples for the new recommended replacement pattern.
+
+- `NoisereduceFilter` is now deprecated and will be removed in a future
+  version. Use other audio filters like `KrispFilter` or `AICFilter`.
+
+- Deprecated `OpenAIRealtimeBetaLLMService` and `AzureRealtimeBetaLLMService`.
+  Use `OpenAIRealtimeLLMService` and `AzureRealtimeLLMService`, respectively.
+  Each service will be removed in an upcoming version, 1.0.0.
+
+### Fixed
+
+- Fixed a `LiveKitTransport` issue where RTVI messages were not properly
+  encoded.
+
+- Add additional fixups to Mistral context messages to ensure they meet
+  Mistral-specific requirements, avoiding Mistral "invalid request" errors.
+
+- Fixed `DailyTransport` transcription handling to gracefully handle missing
+  `rawResponse` field in transcription messages, preventing KeyError crashes.
