basically there is no experimental version anymore. the features that are laid out in the post about the experimental version are now a part of the "stable" version, both pro and lite. so as to which version does more, they should theoretically all be doing the same thing now.

which is to say that your games made in old version will need to have maps converted to use in new version. i would recommend having a copy of both old version and new version. i tried converting my maps from hantolzuca and oskfups from old version to new version, and it's a mess, atleast for my maps. i am gonna redo the maps for hantolzuca from scratch in new version cuz i want to use the new slope floors, and all my other old version projects will be finished in the old version.
