PostCheck 1.6 is now available. I highly recommend this update for any current PostCheck users since it fixes a potentially serious sync services conflict. (Your contacts may disappear while doing batch updates.) I haven’t had any reports regarding this issue yet, which is a good thing of course. I discovered it last night while making some other improvements.
The other updates can, of course, be read on the PostCheck version history page.
PostCheck 1.6 is a free update for all currently registered PostCheck users.
