MBF21 is Boom/MBF with bugfixes and more features. As for what it does, an absolute cockload of stuff.

>more predefined linedef options by far, not just doors and shit but also effects like changing the light level on floors or/and ceilings
>making fake floors to make stuff like knee deep water visuals
>silent teleports
>setting whatever the fuck you want as a sky texture for any sector with sky (can also make the sky scroll)
>scrolling walls in other directions besides left
>scrolling floors, including in ways to move items, monsters, and players (this alone opens up a hundred billion possibilities by creating basically scripted sequences with voodoo dolls)
>generalized linedef functions, so you just define the parameters for a door, crusher, lift, etc, with a few options, rather than pouring through the existing list and hoping what you're looking for is defined
>linedefs which block the player, but not monsters
>linedefs which block walking monsters/players but lets flying monsters pass over
>defining your own animated textures and flats
>defining your own switches
>sector effect which autokills the player if he steps on it (like for deep pitfalls)
>sector effect which does that unless you have invuln or radsuit
>sector effect which kills you and exits you to the next map
>sector effect which kills you and exits you to the secret map
>with a UMAPINFO lump these can really be whatever the fuck you want, too, you can have as many secret levels as you want, or make forked lines of levels
>UMAPINFO would also let you enable and disable originally hardcoded stuff like the Dead Simple 666 and 667 tag specials (as well as redefining what monsters they'll work for)
>also enabling and disabling the MAP30 telefrag behavior on any map
>have text screens for any level you want too, and defining your own episodes
UDMF can do magnitudes more, but MBF21 fits halfway between and is demo compatible.
