GZDoom 3.3.0 has been released. With it, as with every release, comes a wide host of fixes and new features; such things include the long-requested dynamic spotlights, which will certainly make any attempt at flashlights a lot easier, and Timidity++, which has long been a wildly-popular alternative MIDI soundfont. For modders, especially archivist/legacy modders, the fact that custom submenus are no longer removed from the menu should be a magnificent fix in its own right.
However, this release also comes with datamining. For the sake of engine development for future releases, information about your hardware will be sent directly to Graf and Rachael. They claim this is a temporary (and optional!) measure, so if this is something you want to opt out of, either wait until 3.4.0 or say [No] to the run prompt.
