ZK 7.0.0 release notes

Released on November 26, 2013


ZK 7 focuses on improving the theme system, bringing with it the most powerful, flexible yet simple theme engine to date combining the power of CSS 3, LESS and Bootstrap to create the best possible experience.

It is now much easier to create themes from scratch and/or customize existing themes. Leveraging ZK 7, design and development teams will have a much easier job and spend less time creating applications which look great and perform better than ever.
