The new software, version 1.0.2, comes hot on the heels of version 1.0.1, and likewise comes with little in the way of explanation from Apple beyond implementing "bug fixes".
Websites that have downloaded and applied the update claim that the patch improves the performance of the players' Cover Flow feature - the iTunes like feature that allows users to select albums by flicking through the covers. When the Classic and the Nano were released, Cover Flow wasn't as smooth as it was in iTunes or devices like the iPhone and iPod Touch, which also boast the graphical gimmick.
It's also reported that the update improves the synchronisation of calendar and contacts data with host computers. It also modifies the players' video output options, but as yet there's still no TV output support for old third-party docks and other accessories.
iPod Software 1.0.2 is available through iTunes.
