Changelog

New Features:

CEL Support for Workflow Steps: Use CEL (Common Expression Language) expressions as evaluators in Condition, Loop, and Router steps. CEL expressions are strings, making workflow steps fully serializable.
Neosantara model provider: adds support for Neosantara, an Indonesian LLM gateway that provides an OpenAI-compatible API
Studio: Visual editor for building Agents, Teams, and Workflows in AgentOS. Drag-and-drop interface with a Registry for managing tools, models, databases, and schemas.

Workflow Router Step: Added the ability to return name of the Step instead of the step itself as well as support to return a group of steps as a choice for the router
WebsiteReader Chunking: Now uses FixedSizeChunking instead of Semantic by default to remove the need for an OpenAI API key when not setting any specific chunker.
Skills: Add shebang parsing and Windows command building for script execution

LanceDB: Added backward compatibility for deprecated table_names()
Parallel Step: Fixed parallel step in workflows to also accept name as first positional arg.
AzureOpenAI: Fixed AzureOpenAI authentication to include azure_ad_token_provider
Agentic State Tool: Fixed update_session_state tool to correctly extract session_state from run_context after _session_state was removed from the Function class in Agno 2.4.0.
LearningMachine: Add user message to SessionContextStore for Claude/Gemini compatibility.
