- Added logic to ignore "done" messages that are not delta updates, ensuring that final confirmation messages are not sent to OpenAI clients, which rely on finish_reason instead.
- Added support for lifecycle event messages, including a new event type for tracking stream states (e.g., stream_start, stream_end).
- Introduced a NewEventMessage function to create event messages with structured properties.
- Updated the output package to include event messages in the built-in types, ensuring compatibility with CUI clients while remaining silent for OpenAI clients.
- Enhanced the DefaultStreamHandler to utilize event messages for better lifecycle tracking during streaming operations.
- Improved error handling and logging in the OpenAI provider to capture and report streaming errors effectively.
- Implemented a state management system for handling different streaming chunk types, including stream start, group start, text, thinking, tool calls, metadata, errors, and stream end.
- Introduced a new Send method in the context to facilitate message sending to the client.
- Enhanced the output package with message sending capabilities, including support for message groups and flushing.
- Improved error handling and message ID generation for better streaming reliability and user feedback.
- Updated Stream and Run methods in the Assistant to use pointer receivers for context, enhancing performance and clarity.
- Introduced stack management in context handling, including initialization and cleanup of stack references.
- Enhanced the Release method in Context to ensure proper cleanup of resources, including stacks and writer references.
- Added new stack status constants and validation to improve traceability and error handling in agent operations.
- Removed the obsolete JavaScript API file to streamline the codebase.
