We highly encourage you to upgrade to CyberWorldReset Premium because it includes many more features and constant updates.
If you are attempting to update from CyberWorldReset Standard, the plugin will update most of the data on its own! Simply drag and drop the premium jar file in place of the standard jar file.
All Cyber plugin's lang.yml are both forward and backwards compatible. If new strings are introduced, they will appear in lang.yml as default and can be adjusted accordingly. If a lang.yml file is a newer version, you can still use it in an older version of CyberWorldReset. This also means you can use premium lang.yml with the standard version and vise versa.
