Apple has released today a minor update to iTunes on OS X with a fix for a nasty bug that could cause iTunes to crash. The update also includes compatibility improvements with iBooks, Apple says.

The software update follows yesterday’s release of the highly critical OS X 10.9.2 release which filled an existing SSL bug that left users vulnerable to malicious attackers. Apple also introduced FaceTime Audio calling and contact blocking which debuted on iOS 7 last fall.

The update should be rolling out to OS X users through the Mac App Store.
