grpcio-tools 1.30.0

Release v1.30.0

on Python PyPI

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.
