This is the 1.30.2 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 is a patch specifically for the Ruby plugin to address
#23490
Ruby

(#23501)
Release v1.30.1
This release is a patch specifically for the Ruby bindings
Release v1.30.0
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.
Remove unnamed typedef structs in src/core.
Support xDS via both xds and xds-experimental URI schemes.
Fix sorting of gRPCLB addresses when resolved via DNS.
Support local creds in grpc_cli.

gRPC is a modern, open source remote procedure call (RPC) framework
that can run anywhere. It enables client and server applications to
communicate transparently, and makes it easier to build connected
systems.
