C99Koder has updated his site after quite a while with this news update:

Just a quick update today. I’m hoping to have DCBlap 1.0 out within the next few weeks, and I’ll release a list of new features then. An important note, though: If anyone is working on their own DCBlap maps, please wait until the next version to release them. I had to change the file format to support texture alignment, and older maps will not load on the next version of DCBlap. An updated editing guide and a new build of the map compiler will be released along with the next version of DCBlap.
