QuickTime 7.5 fixes bugs
Apple on Monday released QuickTime 7.5, an update to its multimedia software (available for both Macs and PCs). The software, according to the company, improves application compatibility and addresses five security issues; it "is recommended for all QuickTime 7 users." The download is 60MB and available via the Software Update for Tiger, Panther, and Leopard users. In addition, Apple has also posted the QuickTime/MPEG video stream of the keynote. Our own coverage is still available online and we have a full gallery of photos.
