With an update to the Battle.net App Catalog, Blizzard has renamed the old Patch 11.0.7 PTR branch to “PTR 11.1.5”. This means we could see our first public build for Patch 11.1.5 in the near future.
Players can update their Catalog by restarting the Battle.net App. Once updated, look under the Game Versions dropdown menu to see if PTR 11.1.5 is available.
At this time, this version of the PTR still hosts a Patch 11.0.7 build meaning datamining is unavailable.
