Changes in version 2.7.0:
- Players can now open a shulkerbox while having a shulkerbox open by right-clicking it.
- Added the option to make shulkerboxes 'read-only', allowing the players to see the contents but not to modify them unless they place the shulkerbox.
- Added the option to disable 'right-clicking into air to open a shulkerbox'.
- Added plugin metrics (w/bStats), you can disable them by setting 'enable_statistics' to false in config.yml.
- Added "check" subcommand to check for updates (permission required is bettershulkerboxes.updatenotify).
Thanks to ZeLee#4874 for suggesting the first three features.
