Apple has posted an update to OS X to bring it to 10.7.5. The new release, recommended for all Lion users, includes fixes that “improve the stability, compatibility and security of your Mac.”

Specific changes include:

• Resolve an issue where icons in Launchpad may get rearranged after a restart
• Improve Wi-Fi reliability for iMac (Late 2009 and newer)
• Resolve an issue using Spotlight to search an SMB server
• Improve compatibility connecting to Active Directory servers

It’s available through the Software Update system preference and from Apple’s Web site.
