The bad news - no.
The good news, there has been a LOT of work done on the tilemap editor - I can confirm flipped tiles, a new "scratchpad" feature, and tons of UI polish, but I will post in a bit more detail later.
Releasing all this together would have meant delaying 2.0 even further, and would have made the release far too unwieldy to manage. So, once 2.0 final is out there, the next release will have a lot of the tilemap features and other things which didn't make it into 2.0.
