Currently WIP, so no support.
If you want to report a vulnerability, check if it's possible to create an issue without endangering other users. If that's not the case, send a mail to the address on my (its-laika) profile. I check my mails pretty frequently so expect a reply within a few days. From there on, I'll do my best to fix the vulnerability asap. If you want to, you can also provide patches directly or via pull requests. A new version is pushed as soon as the vulnerability is fixed.
