Apple released what is likely to be the last round of fixes to 10.8 Mountain Lion ahead of a look at the next major version of OS X at next week's Worldwide Developer conference.
10.8.4 -- which has been in developer testing for months -- went out Tuesday and fixes a handful of bugs while promising "improvements' in other areas.
Key among them is a fix for a bug in Apple's Messages software that would display messages out of order, an issue that could make the app's conversational style useless and confusing.
On the official change list:
• Compatibility improvements when connecting to certain enterprise Wi-Fi networks
• Microsoft Exchange compatability improvements in Calendar
• A fix for an issue that prevented FaceTime calls to non-U.S. phone numbers
• A fix for an issue that may prevent scheduled sleep after using Boot Camp
• Improved VoiceOver compatability with text in PDF documents
• Includes Safari 6.0.5

Apple has said it will unveil the next version of OS X at WWDC, which kicks off next Monday. The company typically puts its development efforts only into the newer versions of the software, though it has occasionally released standalone security updates to older versions of the OS.
The last minor update to Mountain Lion came back in March, with support for Windows 8 in its Boot Camp software, as well as a fix for a security loophole that could crash apps malicious URLs.
