The September 2010 Release (build 18.104.22.1682) is live: http://mfcmapi.codeplex.com.
My work the past two months on MFCMAPI was all over the map, no real focus. I fixed a few bugs, added some Smart View parsing, and made opening random profile sections a bit easier.
Here's a change list - see the Issue Tracker on Codeplex for more details, or look at the code:
"Hate the way MFCMAPI has to mark profile sections before calling CreateMsgService?"
It's not that I hate MFCMAPI, I hate myself during these moments :) Thanks Steve! CreateMsgServiceEx will come handy.
