Mac OS X 10.5.1 is here

The start of the point upgrades has started in Leopard with 10.5.1, the first update to Leopard and usually the one people wait for before upgrading (if they're sensible).

As you would expect there's
various bug fixes, notably a rather nasty one that could mean a loss of data when moving files.

If you have Leopard you should see it appearing in Software Update, or from
Apple.
