This is release 1.46.0 (golazo) 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.

Announcement

gRPC C++ 1.46 will be the last release supporting C++11, future releases will require C++ >= 14. We plan to backport critical (P0) bugs and security fixes to this release for a year, that is, until 2023-06-01. This change won't bump the major version of gRPC since this doesn't introduce API changes. Hence, the next version requiring C++14 will be 1.47 (context).

1.30.023 Jun 2020

This is the 1.30.0 release (gradius) of gRPC Core.

Please see the notes for the previous releases here: https://github.com/grpc/grpc/releases. Please consult https://grpc.io/ for all information regarding this product.

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

Core

This release adds an xDS URI scheme called xds. This is the stable version of the scheme xds-experimental that was introduced in v1.28.0. xds-experimental scheme will be removed in subsequent releases so you must switch to xds scheme instead. xds scheme is a client side implementation of xDSv2 APIs. This allows a gRPC client written in C++, Python, Ruby, PHP and C# to receive configuration from an xDSv2 API compatible server and use that configuration to load balance RPCs. In this release, only the virtual host matching, default path (“” or “/”) matching and cluster route action are supported. The features supported in a given release are documented here.
