Cableguys have updated Curve 2 to version 2.1.2.
The new version brings an important bug fix for Curve's aliasing mode plus some minor other fixes.
Also, Cableguys improved the syncing of Curve's presets with the online preset library—the major change, besides a speedup, is that with Curve 2.1 also your private presets will be backed up online.
If you ever set up a new computer, simply click "Sync" and not only your public presets and ratings, but also your private presets will be in place again (given you synced them before, of course).
