Although not all features are included in Kendo UI Core. Official Telerik press release can be found here: http://www.telerik.com/company/press-releases/2014/04/16/tel...
Awesome news. I think I read 40+ widgets somewhere this morning and in this press-release it's 38+. Anyways, it's still great.
I hope they will transfer in the OSS packet the grid and the treeview, soon. (nice tripwire :P)
