GPL3 or 2?

Is the Webix license GPLv3 or GPLv2? Everywhere it just mentions ‘GPL’, so does that mean we can assume it to be either of the two (like in case of LGPL).

I’m about to start a project with other components licenced as GPLv2 explicitly, so I wanted to know if I could use Webix.

Hello,

Webix is licensed GPLv3. This is stated on the download page.
