 * Changed sponges to now be disabled by default. However, if you had previously installed WorldGuard, sponges will still be enabled. Sponges are being added in Minecraft and they work differently than in Minecraft Classic (which WorldGuard emulates). In addition, enabling sponge support in WorldGuard incurs extra CPU cost even if no sponges exist in the world.
 * Changed how region data is loaded and saved so failures are now more graceful. If the region data fails to load for a world, then the entire world will be protected by default. In addition, periodic attempts will be made to load the region data in the background.
 * Changed the `FEED` flag to maximize the player's saturation level if the hunger level is raised.
+* Changed the `wg-invincible` and `wg-amphibious` groups feature so that it now must be enabled in the configuration.
 * Removed the ability for WorldGuard to upgrade from a version for Minecraft Alpha.
