K2 0.9.1 was recently released. Semantic classes are now consistent across the board, plus various bug fixes. This version is based on revision 150. Please update your copy of K2. Thanks!
Bring out the champagne (or apple cider if you’re underage) and let’s celebrate! If you’re still using the ancient Beta Two r167, please download and update to the new and hip kay two zero point nine (loves you like a kitten). We’re only 0.1 away from 1.0! 
Here’s a short list of new features for those upgrading from Beta Two r167:
- Sitewide Rolling Archives with AJAX goodness
- New Live Search with integration with Rolling Archives
- Sidebar Modules! Nybble rocks!
- Semantic css classes from Sandbox
- Style information
- Bountiful bug fixes!
How come I got many wide spaces in the post body? any idea on how to fix it?
