I have 2 test programs. I compiled them with FPC 2.0 last week, and now I compiled them with FPC 2.2. The first .exe changed from 7317KB to 11769KB (VCL application). The second one changed from 2036KB to 1615KB (console application). So it seems something was enhanced for console, but maybe the VCL and related libraries increased their size (new features?).

But one thing really increased is the compilation speed. The VCL app has about 60000 lines of code, just from my own programming, and "build all" takes almost the same as Delphi.
