The handling of superimposed objects was improved.
An alternative black-on-white color scheme was
added. A few Doom linedef type definitions and
many Heretic linedef and sector types were fixed.
This release adds 130 more Boom linedef types, hexadecimal integer input, a new (experimental) global editing mode and a new split-doughnut function, as well as somewhat less broken Hexen support. Yadex now shows if several linedefs / sectors are tagged to a sector / linedef. Support for HP-UX, OpenServer, QNX, Solaris and Unixware was improved. Config files are now handled better, and installing to one's home directory works. Shift-F1 and Shift-Ins were revised, and a segfault with save-as on new levels was fixed.
A function to swap the floor and ceiling was added. Sprites are now shown on the map. Heretic and Doom alpha tweaks were made. Strife support was improved. Support for sprites in pwads was added, as well as some support for EDGE.
