Hi,
Today we've released the version 0.9.2 of Klovis. Among bug fixes, refactorings and small improvements, you will notice that there is a new library in the Flex Lib package called "Klovis Flex4 UI". We started to migrate some of the Flex 3 UI Components to Flex 4. Moreover, these components take advantages of the new spark architecture. A default skin is provided with each of them but you can obviously use your own skins 
There is also a minor update of [Kap2Flex] that is compatible with the latest version of Klovis.
Best Regards,
Kap Lab Team.
