• New command /wb wrap [world] <on/off> which will let you toggle border wrapping for the specified world (default off). This will make border crossings in that world wrap the player around to the opposite edge of the border instead of just knocking them back. Requires the new worldborder.wrap permission to use. Thanks to Indiv0 for contributing the main code which allows wrapping.
• New command /wb portal <on/off> which will allow you to disable WorldBorder's portal redirection method that is used to force portal targets to be inside your border (default on). Requires the new worldborder.portal permission to use. This command has been added due to reported incompatibility with the Multiverse plugin, somehow preventing that plugin from creating new portals. I see no reason for that, particularly on WorldBorder's end which simply changes the target location of player Portal travel events, but there you go.
• Fill feature no longer reports number of "skipped" chunks due to that confusing and/or scaring too many people who thought it indicated a bug or something.
