NoIPChat C0.2.0

This release of NoIPChat is special because it's the first one that is externally audited and certified as cryptographically safe when operated with trusted servers.
Every future release with Cx.y.z will represent certified version of NoIPChat. All other versions (doesn't contain letter C) are still developed up to the same standards, but haven't been certified.

It includes:

1. Windows-only version of client available in Windows client.zip
2. Linux and Windows versions of server available in Linux server.zip and Windows server.zip
   Due to the self-contained nature of the releases, platform specific releases can be found inside each .zip file. All dependencies are included.
