MLLE v2.10 has been released, mostly focused on making little improvements to existing windows or menus. For example, if you've been editing a level's palette inside MLLE and realize you need a more sophisticated tool to finish the job, now you can actually export the level's palette instead of having to recreate all your past edits from scratch.

Also, after six years of being grayed out, the "Package in ZIP file" menu option is now functional and has full AngelScript support. I stress-tested it on HH17, and MLLE automatically built a ZIP with 87 of HH17's 88 files, missing only the episode file, which it had no way of knowing about. (Actually, it found an extra file, Icicle.j2a, which I guess was a past filename for HH17_Icicle.j2a but was still being referenced in HH17_Guardian.j2as.)
