This release contains refinements, improvements, and bug fixes, with highlights listed below.

Core

• [Security] Cherry Pick Spiffe Verification. (#​40515)
• [Python][Typeguard] Part 3 - Add Typeguard to AIO stack in tests. (#​40217)
• [c-ares] update version to 1.34.5. (#​39508)
• [pick_first] fix bug that caused us to stop attempting to connect. (#​40162)

C++

• [OTel C++] Implement retry metrics. (#​39195)

Objective-C

• Fix data race by adding custom getter for state property with @synchronized locking. (#​40146)

Python

• gRPC Python (grpcio) now depends on typing-extensions~=4.13. (#​40137)
• Update musllinux wheels from musllinux_1_1 to musllinux_1_2. (#​40317)
  • Dropping musllinux_1_1 because it reached EOL in November 2024
  • Reference on musllinux platform tags: PEP 656
• grpc.aio typehint fixes. (#​40215, #​40217)

  • Serializer parameters: Changed to Optional[SerializingFunction] for more accurate type representation
  • Fixing the error in public API: ClientCallDetails.method was declared as str but always called with bytes, see InterceptedUnaryUnaryCall.
