This release fixes a bug where an exception was thrown when the PlaceholderAPI plugin was not installed.
This release also changes where the localized strings for the currency are located. Before they were located in the config.yml, now they are in the localization files.
If you have a custom localization file, you will need to incorporate these changes.
This release also changes the permissions names to be plugin specific. Permissions starting with bank will now start with piggybank.
