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.
