chatlas is (once again) a soft dependency (included in the providers extra).

py-shinychat 0.2.4

Bug fixes

• Fixed an issue (introduced in v0.2.0) where statically rendered messages with HTML dependencies weren't being handled properly. (#134)

py-shinychat 0.2.3

Bug fixes

• message_content() and message_content_chunk() correctly extract content from a chatlas.Turn. (#133)

py-shinychat 0.2.2

Improvements

• message_content() and message_content_chunk() can now take ChatMessage() as input. (#132)

py-shinychat 0.2.1

New features

• Chat.chat_ui(messages=...) now supports any type also supported by message_content(). (#131)
• ChatMessage() can now be constructed outside of a Shiny session. (#131)

py-shinychat 0.2.0

New features

• New and improved UI for tool calls that occur via chatlas. As a reminder, tool call displays are enabled by setting content="all" in chatlas' .stream() (or .stream_async()) method. See the tests under the pkg-py/tests/playwright/tools directory for inspiration of what is now possible with custom tool displays via the new ToolResultDisplay class. (#107)

• Added new message_content() and message_content_chunk() generic (singledispatch) functions. These functions aren't intended to be called directly by users, but instead, provide an opportunity to teach Chat.append_message()/Chat.append_message_stream() to extract message contents from different types of objects. (#96)

• External links in chat messages in chat_ui() now open in a new tab by default, with a confirmation dialog. (#120)

Bug fixes

• The chat input no longer submits incomplete text when the user has activated IME completions (e.g. while typing in Japanese or Chinese). (#85)

Deprecations

• Numerous Chat() features have been deprecated in preparation for future removal to simplify the API (#91)

  • Chat(messages=...) was deprecated. Use chat.ui(messages=...) instead.
  • Chat(tokenizer=...) was deprecated. This is only relevant for .messages(token_limits=...) which is also now deprecated.
  • All parameters to .messages() were deprecated. This reflects an overall change philosophy for maintaining the conversation history sent to the LLM -- Chat should no longer be responsible for maintaining it -- another stateful object (perhaps the one provided by chatlas, LangChain, etc.) should be used instead. That said, .messages() is still useful if you want to access UI message state.
  • The .transform_user_input and .transform_assistant_response decorators were deprecated. Instead, transformation of input/responses should be done manually and independently of Chat.
  • As a result of the previous deprecations, .user_input(transform=...) was also deprecated.

• We consolidated the <shiny-chat-message> and <shiny-user-message> components into a single <shiny-chat-message> component with a data-role attribute to indicate whether it's an "assistant" or "user" message. This likely has minimal impact on your apps, other than custom styles. You should update any shiny-user-message rules to use shiny-chat-message[data-role="user"]. (#101)

py-shinychat 0.1.0

This first release of the shinychat package simply copies the Chat and MarkdownStream components exactly as they are in version 1.4.0 of shiny. Future versions of shiny will import these components from shinychat. By maintaining these components via a separate library, we can ship features more quickly and independently of shiny.
