These are non-release Git builds. Remember these builds are beta-quality software - use at your own risk!
Reminder: This is a branch of Doom Builder 2, not the original project. This branch is for Ultimate Doom Builder.

A log of recent Git activity can be seen here.
Bugs may be posted here and here.

The only third-party library required to use Ultimate Doom Builder is Microsoft .Net Framework 4.6.1 (should be available by default on Windows 10).
Also, this version requires OpenGL 3.3. In case your system is not compatible, you may try GZDoomBuilder-Bugfix, which is using Direct3D 9.

Note: x86 and x64 architectures are NOT compatible. This means, that:
  • If you upgrade from x86 to x64, you need to do a fresh install;
  • Your x86 plugins won't work with x64 UDB.
If you need some plugins that aren't shipped with UltimateDoomBuilder, either use x86 or ask plugin's author to release a 64-bit version.
