A new version (1.13.1-beta1) has been uploaded. This version brings many bug fixes, and the often requested list command. Note that the permission node for this command (deathchest.list) is not enabled by default, and needs to be explicitly set for users to be able to list their death chest locations. Administrators can also list other players chest locations by adding a username after the command, or list all players death chests by typing an asterisk (*) after the command. Anyone with the deathchest.admin permission node will have the list permissions by default.
As usual, the config.yml and language files have had updates, and should be backed up and removed to allow the plugin to install the new versions. The database schema has not changed, so existing deatchests.db files can be retained.
