Corel subsidiary Procreate has released an updated version of KnockOut 2, its masking software. KnockOut 2 is a plug-in that functions with Adobe Photoshop, Corel Photo-Paint and Painter 7. It enables users to retain details – such as smoke, hair, fire, glass and shadows – while masking out unwanted details. It functions natively in Mac OS X, and also supports Mac OS 8.6 through 9.x. KnockOut 2.88 is the new version. This new release adds support for Adobe's recently released Photoshop 7, the first Mac OS X-native version of Photoshop to hit the streets. Other changes include "significant" overall Mac performance enhancements, improvements to the touch-up tools, better accuracy with the pushpin, syringe and marquee select tools, and enhancements to the colour picker. The 20.7 MB file is available as a StuffIt download from Procreate's Web site. This file updates the release 2.77 version.
