Here's the latest release of my PrBoom fork with UMAPINFO support:   https://github.com/coelckers/prboom-plus/releases/tag/v2.5.1.7um The changelog can be found in the above link   So far there's only a Windows 32 bit version because I am unable to create release packages for macOS and Linux, so any help here is welcome. This has been built with Visual Studio 2019 so there's no Windows XP support.
  Please report issues at the Github issue tracker.
