- Support FlameCord: this server implementation obtains profile properties (including the passphrase) using a different call stack and it was necessary to properly modify the verifier to ensure the passphrase is returned and forwarded to the backend server when joining one. The entire call stack verification logic has been rewritten to support middlewares - call stack elements which may be present when using non-native (BungeeCord in this case) implementations.

- New options: added an option to disable data logging (encoded in base64) when a connection is denied to avoid console spam when not necessary and to not expose sensitive information. Added new options to configure property names for futher compatibility.

- Official support for 1.20: SafeNET had reportedly worked on the latest servers without any issues, so this is just an official confirmation that this release functions as expected on all servers from 1.8 all the way to 1.20.
