Apple on Wednesday released Mac OS X 10.6.5, the latest version of its Snow Leopard operating system. As per usual, the update—which is recommended for all users of 10.6—is chock full of bug fixes, feature enhancements, and security patches.

Among the most prominent additions in 10.6.5 are improved reliability with Microsoft Exchange servers, better stability and performance of graphics applications and games, more robust pairing with Apple’s Magic Trackpad, and improved reliability of Ethernet connections. There’s also now SSL support for iDisk connections, a fix for an issue syncing Address Book contacts with Google, and added support for raw images from a metric ton of digital camera models.

In addition, the update brings plenty of other welcome changes, such as better performance in some iPhoto and Aperture image-processing operations, axing a delay between print jobs, a fix for a problem dragging Address Book contacts into iCal, improved performance of MainStage on certain Macs, resolution of spacing issues with OpenType fonts, better reliability with some Bluetooth braille displays, and a fix for a VoiceOver issue on some Websites when using Safari 5. You can find the full list of changes below.

Also contained in the update are a number of security patches for Snow Leopard, including vulnerabilities in AFP Server, QuickTime, the X11 windowing system, and a truly huge number of security holes in Adobe’s Flash Player plug-in—all of which are apparently fixed by updating the plug-in to version 10.1.102.64. These fixes apply equally to Security Update 2010-007, which is available for users of Mac OS X 10.4 Tiger and later.

There’s no mention in the release notes of AirPrint, Apple’s forthcoming printing feature for iOS, adding weight to reports that Mac OS X 10.6.5 would not bring support for sharing printers with iOS devices.

Apple also released a 10.6.5 update for Mac OS X Server that includes a number of improvements and updates for the server software, including the ability to manage iChat and iCal preferences, improved reliability for Directory Services, an updated version of PHP, and the ability for the Software Update Services to allow administrators to host older software updates (i.e. 10.6.4) after a new version is released (10.6.5, for example).

Mac OS X 10.6.5 and 10.6.5 Server are available now via Software Update—their size will vary depending on your Mac (my 2008 MacBook shows a 517.3MB update for 10.6.5 client).
