Patch 12.1 Overview
While there has not been an official release date of Patch 12.1, many players have been speculating that August 11th is the release date of the Patch, and August 18th for Season 2 due to many reasons. As a release candidate build, this is likely one of the last full PTR builds, though though there are often still pre and post-release hotfixes which continue to make adjustments as needed. According to Ion Hazzikostas, most of the major changes should be done at this point to avoid last minute changes to break other things.
Release candidates usually appear on the PTR around 2-3 weeks before the official release date. For example, the release candidate for Patch 12.0.7 occurred on May 27th, and the official release date was on June 16th.
