Apple didn't make a song and dance about its recent upgrade - Mac OS X Server 10.4.7, which transformed Apple's server software into a Universal binary that works natively on both PowerPC and Intel-based Macs.

It's likely the company effectively buried this news because it released the update at the end of June - weeks before it unveiled its new Intel Xeon processor-powered Xserve.

In an interesting twist, the company is also making its server software available as a build-to-order option to customers ordering a new Mac Pro.

The company is also shipping a new boxed retail version of the product. The Mac OS X Server 10.4.7 retail package now only includes an installation DVD and an Admin Tools CD. The installers no longer ship on the CD.

Otherwise, the release fixed several problems in the software, including several enhancements to AFP server usage, SAN, RAID and Kerberos improvements.
