Release notes

Sourced from grpcio's releases.

Release v1.73.0

This is release 1.73.0 (gradient) of gRPC Core.

For gRPC documentation, see grpc.io. For previous releases, see Releases.

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

Core

As of this version, gRPC on MacOS & iOS will utilize Abseil's synchronization features, aligning it with other platforms. Should you encounter any issues due to this update, you can disable it by enabling GPR_DISABLE_ABSEIL_SYNC. If you do this, please report any problems by filing a bug at https://github.com/grpc/grpc.

• [Dep] Update Protobuf to v31.0. (#39392)
• [Core] Added GPR_DISABLE_ABSEIL_SYNC. (#39562)
• [xds_override_host] pass through per-endpoint args when creating subchannels. (#39532)
• Expose GRPC_OPENSSL_CLEANUP_TIMEOUT to control shutdown grace period. (#39297)
• [URI] fix parsing of user_info in proxy settings. (#39004)
• [EventEngine] Fix busy loop in thread pool when shutting down. (#39258)
• [Dep] Added a flag to build with openssl instead of boringssl. (#39188)
• [EventEngine] Cleanup: EventEngine client, listener, and dns experiments are on by default on all platforms. (#39079)

C++

• [OpenCensus] Mark OpenCensus and dependent APIs as deprecated. (#39554)

Python

• [Python] Pin Cython to 3.1.1. (#39609)
• [Python] grpc_tools: make PythonGrpcGenerator handle dot . in proto paths the same way as native Generator/PyiGenerator. (#39586)

Ruby

• [Ruby] add remove_unused_artifacts to opt build. (#39593)

gRPC Release Schedule

Below is the release schedule for gRPC Java, Go and Core and its dependent languages C++, C#, Objective-C, PHP, Python and Ruby.

Releases are scheduled every six weeks on Tuesdays on a best effort basis. In some unavoidable situations a release may be delayed or released early or a language may skip a release altogether and do the next release to catch up with other languages. See the past releases in the links above. A six-week cycle gives us a good balance between delivering new features/fixes quickly and keeping the release overhead low.

The gRPC release support policy can be found here.

Releases are cut from release branches. For Core and Java repos, the release branch is cut two weeks before the scheduled release date. For Go, the branch is cut just before the release. An RC (release candidate) is published for Core and its dependent languages just after the branch cut. This RC is later promoted to release version if no further changes are made to the release branch. We do our best to keep head of master branch stable at all times regardless of release schedule. Daily build packages from master branch for C#, PHP, Python, Ruby and Protoc plugins are published on packages.grpc.io. If you depend on gRPC in production we recommend to set up your CI system to test the RCs and, if possible, the daily builds.

Names of gRPC releases are here.
