Well that was some unexpected humour from the bitcoin mining crowd. I grinned I guess the improving price of BTC has improved people's moods.
2.0.9 was a development version number only, and yes the minor version upgrade (as opposed to micro version) signifies the feature upgrade to the RPC API.
If you pulled from git and are still getting version 2.0.9 it's because you didn't do ./autogen.sh
As for windows, as I said I've thrown it in the debugger heaps of times and the bug goes away in it so it's proving undebuggable (a Heisenbug). (I do believe it's some windows versions only). So you're out of luck unless you wish to run cgminer without the curses display (i.e. start it with -T).
