patch

Pydantic-AI version 2.39.0 has been released, focusing entirely on resolving several critical bugs. Key fixes include addressing `context_subtree()` exporter cache and span-processor leaks, restoring an instrumentation spec option, and improving detection of Azure content-filter errors. The update also refines the handling of speech finalized by tool calls and attribution of tool-returned media. These patches enhance the stability and reliability of the Pydantic-AI library, particularly for developers integrating with Azure services and managing media-rich AI interactions.
