Finally after a few weeks of development and a huge chunk of codebase changed this feature is ready

New features:

• Now you can enable automatic whitelisting for new players on your server! Check your configuration file for more details.
  
• 12 new commands to control the feature under main /auto-whitelist command.
  
• A system that will automatically migrate your configuration files and database table schema if needed.
  
• Full description for all permissions to make it easier to use in conjunction with plugins like LuckPerms. b21ff51 f673ed9

Compatibility note:

• WhitelistImportEvent was deleted. c4d4f89 7ba1fe
  This change improves overall ram consumption, the event should've not existed in the first place.
  
• whitelist database table schema was changed b04245d:
  • uniqueId -> unique_id
  • expiresAt -> expires_at
    You will not need to update your table schema manually, I built an integrated migration module that will handle it and possible further updates to the schema. Although, you might need to update your backend applications if they used this table.
• Permission for on/off commands were changed to match command names d7d0f93:
  • voidwhitelist.whitelist.enable -> voidwhitelist.whitelist.on
  • voidwhitelist.whitelist.disable -> voidwhitelist.whitelist.off

Bugfixes:

• Fixed Whitelistable entity update not being save with JSON storage. 61986d2
• LoginListener now ignores cancelled events (it's funny how long it wasn't a thing and literally noone noticed ) 917cfd7

Full changelog:

• Feature/auto whitelist by @voidpointer0x00 in #16
• v0.9.5...v1.0.0-stable
