What's New

Upgrades to DSPy 3.3.0 with Flex optimizer and typed LM API, replacing v2.6.1's bug fixes

Breaking Changes

Resource constructors for Image, Audio, and File no longer perform implicit I/O
Custom LMs must implement the typed LMRequest -> LMResponse contract
LiteLLM imports are now lazy and optional

New Features

Experimental Flex optimizer for program structure via GEPA
Native-tool-aware ReActV2 implementation with history support
Typed LMRequest and LMResponse API for provider neutrality
BaseLM state serialization with dump_state and load_state

Improvements

Native tool-call history support
Lazy and optional LiteLLM imports

Upgrade Notes

Review API changes for Image, Audio, and File constructors; use explicit methods like from_path or from_url. Ensure custom LMs implement the new typed LMRequest -> LMResponse contract. Review GEPA results and tool-call history support if applicable.
