Chocolate Doom 3.1.0 brings many new features for the classic source port

While other source ports are pretty popular like GZDoom, Chocolate Doom continues getting better to retain the best compatibility with the original DOS versions of Doom, Doom II, Heretic, Hexen and Strife. It's been quite a few years too, with the last main release of Chocolate Doom being back in 2017.

Some of the new features included in Chocolate Doom v3.1.0:

• WAD file autoloading was added - WAD and DEH files can be copied into an autoload folder to be automatically included on every game start.
• MP3 music packs are now supported.
• Network synchronization now uses a PID controller by default, which makes games more smooth and more stable, especially for Internet play.
• UDP hole punching is now used to make servers behind NAT gateways.
  automatically accessible to the Internet.
• The IWAD files installed by Steam on Linux are now detected.
• The Freedoom single-player IWAD files are now officially supported, since recent versions changed all levels to be vanilla compatible.
• Add improved gamepad support via the SDL_GameController interface. This includes support for analog triggers, modern dual-stick default bindings (based on Unity Doom), descriptive button names for common controller types and configurable dead zones for stick axes.
• Doom 1.2 demo support was added.
• + lots and lots more.
