+## 0.6.4

+
+* expanded the `messageSender` docs on `LlmChatView` to make it clear what it's for and when it's used
+
+* renamed FatXxx to ToolkitXxx e.g. FatColors => ToolkitColors
+
+* fixed #77: move dark theming to the samples and out of the toolkit, since it has no designer input

+
+* fixed #55: TextField overflow error for large inputs
+
+* fixed #39: bug: notify developer of invalid API key on the web
+
+* fixed #18: Gemini or Vertex + the web + a file attachment == hang

+
+* simplifying the `LlmProvider` interface for implementors
+
+## 0.5.0
+
+* fixed #67: bug: audio recording translation repopulated after history cleared
+
+* fixed #68: bug: need suggestion styling
+
+* implemented #72: feature: move welcome message to the LlmChatView

+
+* implemented #74: remove controllers as an unnecessary abstraction
+
+* fixed an issue where canceling an operation w/ no response yet will continue showing the progress indicator.
+
+
+## 0.4.2
+
+* upgraded to waveform_recorder 1.3.0
+
+* fix #69: SDK dependency conflict by lowering sdk requirement to 3.4.0

+
+## 0.2.0
+
+* implemented #33: feature: chat microphone only prompt input
+
+* added a `generateStream` method to `LlmProvider` to support talking to the underlying generative model w/o adding to the chat history; moved `chatModel` properties in the Gemini and Vertex providers to use a more generic `generativeModel` to make it clear which model is being used for both `sendMessageStream` and `generateStream`.
+
+* moved from [flutter_markdown_selectionarea](https://pub.dev/packages/flutter_markdown_selectionarea) to plain ol' [flutter_markdown](https://pub.dev/packages/flutter_markdown) which does now support selection if you ask it nicely.
