CodeWeavers announced version 8 of their software for Linux and Mac. Crossover is software that allows you to run windows apps on non-windows platforms (if you didn't already know). The new version boasts a bunch of new apps available out of the box, plus lots of improvements in the ones there already (ie: office, outlook, IE7, etc).
Sadly I think the need for Crossover isn't nearly as great anymore. With things like Evolution's Exchange connector and OpenOffice.org out there for free, dealing with an emulation layer just isn't as imperative. Course, there are some apps that have nothing like them in the non-windows world that put Crossover in a good spot.
