View releases on GitHubNew Features:
Improvements:
Bug Fixes:
- Fixed Run Command Import Functionality: The run command was not properly importing other files from the same directory or project structure. This has been fixed by correctly setting up sys.path, package, and name attributes to ensure proper module resolution and relative imports work correctly when executing agents.

v0.66.1
View releases on GitHubImprovements:
- Ollama Model Configuration: Enhanced Ollama provider integration by enabling “model as string” support, allowing simplified string-based model configuration instead of requiring model class instantiation. Users can now specify Ollama models using the convenient
"ollama/model-name"string format, making it easier to switch between models and configure them via environment variables.
Bug Fixes:
- Model Configuration: Improved model initialization flow for Ollama provider to ensure proper string-based model handling and compatibility with existing Upsonic model interfaces.
Pull Requests:
- Model as string ollama: @onuratakan in #463

v0.66.0
View releases on GitHubNew Features:
- Expression Language: Introduced Upsonic Expression Language (UEL) enabling declarative chain composition with pipe operators, runnables, and dynamic workflow construction for building sophisticated AI agent pipelines.
- State Graph and Recursive Tool Handling for Streaming: Added recursive tool handling capabilities for streaming in Agent class and StateGraph logic.
Improvements:
- MCP Smoke Test Coverage: Added comprehensive smoke tests for Model Context Protocol (MCP) integration to ensure reliable MCP server connections and tool discovery functionality.
Bug Fixes:
- External Tool Execution: Fixed issues with external tool execution handling that prevented proper pausing and resumption of agent workflows when tools require external processing.
- Logging and Memory Error Handling: Resolved logging inconsistencies and added robust error handling for memory operations to prevent framework crashes during memory storage and retrieval operations.
- Documentation Links: Fixed broken links in README documentation to ensure accurate navigation and improve developer experience.
Pull Requests:
- Expression Language: @DoganK01 in #453
