That's right!
OneLife will now (optionally) log death-related information into a separate log-file.

You can enable DeathLogger by setting 'enable-deathlogger' to true.
Make sure to delete the existing config file, and reload/restart the server.

For this update it is also required to delete the existing en-US.yml localization file.
If you have a custom localization file, add these keys to it. Follow the indentation, and make sure you reload/restart the server after changing any localization info.
Added keys:
deathlogger.logmsg [placholders: %player%, %deathPosition%, %deathExpiration%]
deathlogger.logmsg-dead [placeholders: %player%, %deathPosition%, %lives%]
