Raskin Software (http://raskinformac.com/) has updated its self-titled Raskin application — a zoomable single surface Finder alternative for the Mac — to version 1.8.3. The upgrade sports minor bug fixes.

Raskin requires Mac OS X 10.6.3 or higher. It’s available for 40% off its normal US$24.99 today at the Mac App Store or the Raskin Software web site (www.raskininformac.com). A 30-day demo is available for download at the latter. Raskin 1.8.3 is a free update for registered users.
