The new and improved CodeWeavers 
CrossOver version 10.0.0 was recently  released, So if you need a Windows Application or Games to run on Linux, Mac OS X, FreeBSD or Solaris this is your chance to get it at 20% off the normal selling  price.
CrossOver 10.0.0 contains many fixes to existing applications, and just  generally makes the product better. As of this writing CrossOver has  been merged with Wine 1.3.9 and contains many improvements for Internet  Explorer, Microsoft Office, Quicken, PhotoShop and many other supported  and none supported applications. See below for the full changelog of changes in CrossOver 10.0.0 for Linux and Mac.
Second, and perhaps most important, the CrossOver installer will now be  directly linked to their online Compatibility database and allow people  to install unsupported software via (recipes) contained on the  Compatibility Center. The recipes are now called CrossTie and have the .tie file extention.
Technically speaking, a CrossTie file is a formatted XML file. When you click on a  CrossTie link in our Compatibility Database, you'll be prompted to download  the the CrossTie file to your machine. After downloading the CrossTie file, on 
Mac  you can drag and drop the CrossTie file onto the CrossOver icon, or double  click on the CrossTie file to have CrossOver load the file.
On 
Linux  you can double-click on the CrossTie file, right-click and choose "Open  With-->Crossover", or if you're a command-line junky, you can open  the file with :
$ ~/cxoffice/bin/cxinstaller installerfile.tie
CrossOver reads the XML 'recipe' and begins the installation process for  the target application. The CrossTie file tells CrossOver everything it  needs to know about how to install the target software package, how to  detect if it is installed, and even how to determine what software  package a given CD is for. CrossOver will also automatically understand  all the dependencies, tweaks and settings that would be needed to make  that application install and function to the best of its ability.
Here is a couple screenshots of the  
Crossover Professional 10.0 (UI) user interface.
