# Release Branches

Release branches have a name of `release-MAJOR.MINOR`. Essential Istio repositories are branched from master roughly 4
weeks prior to a new release. The `istio/istio.io` repository does not get branched until the release is ready
for publication.

This document outlines getting in new features after a new branch has been cut and the process for getting a PR
merged in before and after the first public release.
