Where is DHTMLX 5.X

After a lot of time spent on your website, I can’t find where to download the suite 5.x.

When I go on your GitHub and I select the branch named 5.x, the “readme” says : " dhtmlxSuite v.4.5.1 Standard edition".

I found the documetation for versions 5 & 6, but not for 4.5.x.

Can someone please explain me where to find version 5.x?

Best Regards
