Change log
Website

• Added a 'Hour by Hour' graph similar to 'Day by Day' graph to server and network pages. It displays hourly new players and unique players for the last 7 days.

Error handling

• Error handling was rewritten to address the issue of large error log files. Now each exception is assigned an unique hash to avoid duplicates of same exception being logged.
  
  • Error context was added so that it is easier to solve issues
  • The context can also include "What to do" instructions to the user in case they can fix the issue themselves, in cases like File permission errors.
  • Up to 5 contexts are logged in order to avoid these log files from growing endlessly.
  • Error stacktraces are no longer logged to console to avoid console logs becoming large.
  • Default log deletion setting was reverted back to 7 days
• Extension method disabling (if a method throws an exception) should now work properly

Locale

• Chinese locale was updated by Fur_xia and Karlatemp
• Deutsch locale was updated by hallo1142
• Spanish locale was updated by itaquito
• Some pages erroring when using a locale were fixed by Karlatemp
• Some links getting translated was fixed by Karlatemp

Other

• Update check is now performed asynchronously on enable (by Karlatemp)
• A typo in a comment in ServerInfoFile.yml was fixed by aimorris
• Registration information now expires after 15 minutes (Fixes a memory leak)
