If Im not mistaken (my russians a bit rusty) there are a few things unique with this update.
First, he redid a vast majority of the images and webms and what not so there's a need to download the ENTIRE game file all over.
Second, he also rewrote and restructured a lot of the code base,far from everything, but enough to where most of our quick and dirty patches the users so generously provide actually fudge the new adjustments or stay connected to variables that dont exist in its present state. So the cheats specifically are bound to be affected.
and lastly third, Im fairly certain with reviewing the comments on his blog theres a ton of bugs in his new system he needs to repair before any meaningful 3rd party mods will be of any use.
Unlike last time he disappeared (illness) he was actually working on this update throughout so its a pretty hefty bit of redesign that probably might not be fully resolved until 30 drops. Just something to keep in mind I guess, I dont mean to be a downer.
