Connectix Corporation has released Speed Doubler 8.1.1, an update to its popular performance enhancing software for the Mac OS. (See "Speed Doubler 8" in TidBITS 402.) Speed Doubler 8.1.1 works with the forthcoming Mac OS 8.5, improves compatibility with Mac OS Easy Open, StuffIt SpaceSaver, third party file systems and storage devices, and utilities (like the shareware FinderPop) that allow items to be copied from places other than Finder windows. Speed Doubler's Keyboard Power feature - which enables users to navigate application menus via the keyboard - has also been completely written and is now PowerPC-native. Owners of any version of Speed Doubler 8 can download a free 750K updater from Connectix.
