Release v1.30.0

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.
• Remove unnamed typedef structs in src/core. (#23082)
• Support xDS via both xds and xds-experimental URI schemes. (#23105)
• Fix sorting of gRPCLB addresses when resolved via DNS. (#23086)

• Include the destination address in synchronous TCP connect errors. (#22868)
• Use aligned calculation to determine transport stream from call data. (#22730)
• Fixing bug with END_STREAM if header has continuations. (#22626)
• Fail writes when End of stream has been received. (#22668)

C++

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 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.

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.

Release	Scheduled Branch Cut	Scheduled Release Date
v1.17.0	Nov 19, 2018	Dec 4, 2018
v1.18.0	Jan 2, 2019	Jan 15, 2019
