What's Changed

Python

• Release grpcio wheels with Python 3.14 support (#​40403)
• Asyncio: fixes grpc shutdown race condition occurring during python interpreter finalizations. (#​40447)
  • This also addresses previously reported issues with empty error message on Python interpreter exit (Error in sys.excepthook:/Original exception was: empty): #​36655, #​38679, #​33342
• Python 3.14: preserve current behavior when using grpc.aio async methods outside of a running event loop. (#​40750)
  • Note: using async methods outside of a running event loop is discouraged by Python, and will be deprecated in future gRPC releases. Please use the asyncio.run() function (or asyncio.Runner for custom loop factories). For interactive mode, use dedicated asyncio REPL: python -m asyncio.
