gRPC v1.32.2 Release Notes

Release Date: 2020-10-12 // over 3 years ago

  • 🐛 Bug Fixes

    • netty: TCP close during TLS handshake should be UNAVAILABLE, not UNKNOWN
    • netty: BDP ping accounting should occur after flow control. This resolves an incompatibility issue introduced in v1.30.0 and could be worked around via GRPC_EXPERIMENTAL_AUTOFLOWCONTROL=false introduced later. The symptom was a GOAWAY with “too_many_pings” without an aggressive keepalive configured. The environment variable is still available, but will be removed in the future
    • 🚀 alts: Reverted workaround for Conscrypt cipher performance. Conscrypt 2.5.0 has significantly improved performance and the workaround now decreases performance. Note that grpc-alts itself still depends on Conscrypt 2.2.1 to remain stable for this bug fix release, but users are encouraged to use newer a version of Conscrypt. The gains from Conscrypt 2.5.0 are significantly greater than what the workaround provided
