Last October 8, Apache Friends released new versions of XAMMP for Windows, Linux and Mac OS X. I use XAMMP on Windows, but for Mac OS X, I use MAMP - the Mac OS X release of XAMMP is still in its early stages.

They have updated the following:

• Apache to 2.2.6
• PHP to 5.2.4
• phpMyAdmin to 2.11.1
