The release notes for Update 15.3 are available on the forums. As expected, this update has addressed the music system, but there were some other fixes included as well. Two of the more significant changes that caught my eye were the following:
- The OSX Launcher will no longer download all the splash screens every time you start it. It does make an HTTP request for each splash screen to see if you have the most recent one on disk each time.
- Morskor in Barad Guldur will no longer become invisible every time he takes flight.
