Update: Sparrow for Mac 1.6.2 is now live in the Mac App Store, ten days after its debut for users who purchased the app from the Sparrow store.

Another app has been updated to support the MacBook Pro with Retina display — this time it's Sparrow, the popular (and Gmail-friendly) desktop email app. The new version (1.6.2) has just been pushed out, and for users of Apple's high-resolution laptop the difference is stark: the sidebar and message previews are now both Retina-compatible, as are all icons and menus. Other than the high-res support, the update also makes the application Mountain Lion-ready and fixes a bug with Growl 1.3 compatibility. Check the full changelog below, and beware that these updates are often released first to those who downloaded the app directly from Sparrow (rather than the Mac App Store).
