1. Bots can now pass attachments to each other via fp.stream_request. To do this, call the post_message_attachment function, which continues to work like before, but will now also implicitly emit a file event to other server bots calling it. Calling bots will receive the file in the attachment field of a PartialResponse from the bot.
2. OpenAI tool calling improvement: the request will finish without making an extra unnecessary second call to the OpenAI bot if no tools are decided to be called. This saves cost to the user.

This release adds the new DataResponse object which bots can yield to attach a metadata string to their response. This string can be accessed in the metadata field of the associated ProtocolMessage in future requests to the bot. This is useful for storing additional information about previous messages in the conversation.

If allow_attachments and expand_text_attachments are both True, PDF files uploaded by the users will have their contents automatically appended to the conversation for the model to reference. This previously only worked for text and html files.

Previously, when defining server_bot_dependencies there was a limit of 10 calls to other bots for a single message. This limit has been increased to 100 calls for a single message.

• Updated the suggested optimized Poe Previews prompt to better support React. See https://creator.poe.com/docs/how-to-create-a-prompt-bot#optimize-prompt-for-previews for the full prompt

• We updated the fastapi_poe library to require Python >=3.9, as Python 3.8 reached end of life in October 2024.
• This version also includes a fix for tool calls failing when the model decides not to call the function.

• Added ability for server bots to help users create prompt bots with pre-filled fields. See https://creator.poe.com/docs/server-bots-functional-guides#creating-bots-that-help-their-users-create-prompt-bots for more details.

• Added download_filename for specifying a filename when downloading from url. Previously the filename from the download_url was always used. This enables bots to set a custom filename for attachments they post via download_url.

• Users can now call sync_bot_settings using fp.sync_bot_settings() directly

• Prior to this change, the text field of ErrorResponse was not displayed on the client and errors always showed the text "Bot x ran into an unexpected issue". With this change, the text field is now displayed to the user, allowing for custom error messages. It is recommended to put the raw exception in the raw_response field instead.
