To be honest, we don't even know whether it even works. However, this version (unlike classic) is maintained and we will be happy to accept your bugreports "in our bug-tracker":https://phabricator.dsrev.ru/project/view/1/. You should also be able to submit them using "ticketing system":https://openvk2.veselcraft.ru/support?act=new (you will need an OVK account for this).
However, OVK makes use of Chandler Application Server. This software requires extensions, that may not be provided by your hosting provider (namely, sodium and yaml. this extensions are available on most of ISPManager hostings).
Simply put, we would recommend you to use latest CentOS (running on your own VDS/Dedicated) with latest PHP from EPEL. We used to have this configuration on our "testing instance":https://openvk2.veselcraft.ru/ and thus will be able to provide quicker support for OVK running in this environment. Currently we use Windows Server 2012R2 with IIS and PHP from Web Marketplace and you can use this setup too and expect some support with it.
Right now not. But we will add upgrading script soon.
h3. If my website uses OpenVK, should I publish it's soures?
You are encouraged to do so. We don't enforce this though. You can keep your sources to yourself (unless you distribute your OpenVK distro to other people).
You also not required to publish source texts of your themepacks and plugins.
*Attention*: bug tracker and telegram chat are public places. And ticketing system is being served by volounteers. If you need to report something, that shouldn't be immediately disclosed to general public (for instance, vulnerability report), *please use contact us directly*:
