Upgrade to Wheels 0.8.1

We just put up a bug fix release that fixes a few critical errors with the 0.8 version:

• Problem when placing application in a sub folder is now taken care of.
• An error when trying to nullify a field is now fixed.
• Missing rewrite rules for Apache are now included in the zip file again.
• Wheels now runs fine on case sensitive operating systems once again.

You can download it from here. Thanks to everyone who reported errors and helped us test the solutions!
