OpenVPN Hackathon 2021

This year's hackathon is jointly organized by Gert Döring (community part) and Arne Schwabe (closed part).

We will stick to the format of the previous years, which means attendance is in principle limited to "active developers that are also regularly contributing to #openvpn-devel or the mailing list". We have enough space in the meeting room for 20 devs (covid19 restrictions, the room is much bigger).

Full vaccination against covid19 is required.

Please also read the border entry regulations from German government at:

tl;dr: you have to pre-register if traveling from a high risk area and basically always have to be vaccinated
