Toon Boom Technologies will be offering a “sneak peek” of Toon Boom Studio 2.5 for the Mac this week at Macworld Expo. The update –- due in the spring — will include several new features, such as sound scrubbing in the Timeline, the ability to draw in Sceneplanning and support for scanning. All current customers using version 1.2 who have registered their license key at the Toon Boom Web site will receive the upgrade electronically at no charge.
