Changelog

​

v0.66.1

​

Improvements:

• 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

​

New 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
• smoke test for mcp added: @sxroads in #454
• docs: fix broken links in README: @gokborayilmaz in #456

​

v0.65.1

​

New Features:

• Centralized Logging System: Introduced a unified logging configuration system that replaces ad-hoc logging instances across the framework, providing consistent logging behavior and centralized control.
• Sentry Integration: Added comprehensive Sentry integration for telemetry and error tracking, enabling better monitoring and debugging of agent executions and pipeline operations.

​

Improvements:

• Improved Logging Configuration: Enhanced logging system with flexible module-level log control, multiple format options, and environment variable-based configuration for better developer experience.
• Pipeline Tracing: Added systematic transaction and span tracking in pipeline manager for improved observability and debugging of agent execution flows.

​

Bug Fixes:

• Fixed Logging Issues: Resolved logging problems and inconsistencies across the framework by implementing a centralized logging system with proper error handling.

​

Pull Requests:

• Redesigned Logging system: @onuratakan in #452
