Iconfactory today announced the release of IconBuilder 8.5, the latest version of its professional Photoshop and Fireworks filter for creating icons on the Macintosh. The filter’s architecture has been re-engineered from the ground up in Xcode to take advantage of Adobe CS3’s new plug-in structure and is optimized for use with Apple’s Intel line of Macs. IconBuilder allows icon artists to harness the powerful feature sets of Adobe Photoshop and Fireworks to create professional, high-quality icons for both Mac OS X and Windows Vista quickly and easily. IconBuilder 8.5 is available now for Mac OS X for US$79. Users who purchased IconBuilder 8.x after January 1, 2007 are entitled to a free upgrade — the upgrade price for prior purchases is $30.
