Nothing that looks like a problem on my end here at any rate. Excellent speed of metadata transfer in the latest full cycle (after upgrade to calibre 1.6). I've also noticed that browsing by tags actually seems to work a little bit faster since the 3.2.x release, even when there's over 10k books on device, though possibly it's also the upgrade to Android Jelly Bean that's had this salutary effect.
And best of all I've not had my CC database blow up in my face in weeks, which of course is something I am very happy about.
