It was a busy Tuesday for Apple's software team. The company released updates for its Safari Web browser, its wireless AirPort client, and the Multi-Touch trackpad for users who have Windows installed on their Mac.
Safari 4.0.3 comes just six days after Apple released an upgrade for Safari 4.0.2 as part of its Mac OS X Leopard 10.5.8 update, indicating fixes were not implemented in the previous version or problems were caused by its release.
Among the changes in Safari 4.0.3 are several stability improvements, including enhancements for Web pages that use the HTML 5 video tag, third-party plug-ins, and Safari's Top Sites feature. The update also corrected a problem that prevented some users from being able to log in to iWork.com and fixed an issue that caused some Web content to be displayed in grayscale.
Several of the changes in Safari affect the security of the application, and are fixes for flaws that could allow hackers to execute code on the user's machine.
The AirPort client update is recommended for users of 13-inch MacBooks from late 2007 and 2008, 15-inch MacBook Pros from 2008, and 17-inch MacBook Pros from 2008. Again indicating the problem was caused by Mac OS X Leopard 10.5.8, the update is only required for those computers with the newest operating system.
The final update, Multi-Touch Trackpad Update 1.1 for Windows, is for users who installed Windows XP or Vista on their Mac using Boot Camp. The update, according to Apple, improves performance of the multitouch trackpad.
