Wait, so jacob, my noticing of the way air is handled was correct?
I noticed the ambient heat thing, i forgot to add it
I've noticed the loop feature. If you fill the screen with EHOL and have loop enabled, it causes innumerable glitches when you place powders.
Ok I feel like saying more because why not. The profile viewer was improved, deco flood fill was added, save search signs were added, and ambient heat now shows in the HUD. I bet you didn't know all of these things :). Unless you already read the changelog ... which I really should compile into a single list sometime. Right now it is split into 4.
Yeah, particle only wall was added in 90.0 I think. Also C-4 hasn't changed colors at all as far as I know. I dug up some even more obscure things from the changelogs though! FRZZ/FRZW were "fixed", they didn't work as intended before at all due to a bug. When drawing near a zoom window, it will no longer make a massive jump from inside the zoom window to outside it (it instead cancels the drawing). The tooltips for the save upload button changed. Streamlines, EMP, ETRD are less laggy. And more!
The particle only wall was already there
