- Introduced mechanisms to handle agent-to-agent (A2A) calls, including automatic history skipping for forked calls and proper source tracking.
- Enhanced context management with the addition of ForkParentInfo to facilitate child stack creation without race conditions.
- Updated JSAPI methods to ensure correct handling of sub-agent calls, maintaining output isolation and preventing history pollution.
- Improved documentation to clarify the behavior of A2A calls and context management in concurrent scenarios.
- Updated the completion request parsing logic to make the model field optional, allowing for better flexibility in handling requests.
- Enhanced the stream end handling by adding JSON parsing for stream end data and sending a structured message to the frontend.
- Modified the output writer to format data as Server-Sent Events (SSE) and ensured immediate flushing for real-time streaming in both CUI and OpenAI adapters.
- Refactored the Stream method to retrieve connector capabilities early, allowing output adapters to utilize them effectively.
- Introduced a new Info method in the Assistant to provide structured assistant information, enhancing context accessibility.
- Updated StreamStartData to include additional fields such as ChatID and Assistant info for better event tracking.
- Improved error handling in the Stream method to ensure robust management of connector retrieval failures.
- Enhanced internationalization support for stream event messages, providing localized output for different clients.
- Integrated i18n translations for trace logging messages in the Assistant's Stream method, improving localization for user-facing messages.
- Updated logging in the OpenAI provider and CUI writer to utilize i18n for error messages, enhancing clarity and consistency across different locales.
- Added new embedded template handling in the i18n package, allowing for more flexible message formatting with variable substitutions.
- Improved test coverage for i18n functionalities, ensuring robust handling of various translation scenarios and edge cases.
- Integrated trace management into the Assistant's Stream method, allowing for detailed logging of processing steps and errors.
- Improved error handling in the OpenAI stream and post methods, adding trace logs for retries and failures.
- Enhanced CUI and OpenAI writers to log message adaptation and sending errors, improving debugging capabilities.
- Updated trace manager to use milliseconds for timestamps, ensuring consistency across the trace system.
- Refactored log methods in the trace node to streamline logging and broadcasting of events.
- 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.
