Last week, LauncherPro's Federico Carnales launched a beta version of the new LP Plus with skinnable widget support, and this update, tagged 0.8.5, made its way into the Market as of this morning. Skins can be downloaded and installed as regular Android apps from the Market or from 3rd party websites (sorry, AT&T users) and then applied to LauncherPro Plus (you need the Plus edition to have widgets).
Besides skins, the new version brings reduced memory usage, improved scrolling performance, and calendar widget daylight savings bug fixes.
As always, you can grab the latest version from the Market or the official LauncherPro site.
Those interested in widget skinning, head over to this forum post that discusses it in great detail.
