This release introduces significant decoupling from LiteLLM by moving capability checks to BaseLM and introducing a DSPy-owned error type, while also enhancing optimizer chaining with BetterTogether. Security and stability improvements were made across RLM, PythonInterpreter, and cache handling, including an opt-in restricted pickle mode for disk cache.

This release adds new tooling APIs, improves networking headers, and introduces several bug fixes and documentation updates.

DSPy 3.0.0b2 introduces new LM providers, async adapters, and extensive cleanup, but also removes several legacy APIs and drops Python 3.9 support, requiring code updates.

This release removes deprecated functional and dsp clients, adds streaming, a sandboxed interpreter, retry support, and several feature enhancements while fixing literal handling bugs.

This release adds trusted library imports for the PythonInterpreter sandbox, enhances argument parsing for dspy.ReAct, improves literal handling in adapters, and includes several bug fixes and documentation updates.
