This version adds a new "ifMemberOfRegion" condition, which can be used to check whether or not a player is a member of the world guard region they're in. Like this:

ifMemberOfRegion: true

It also makes a minor change to how other WorldGuard actions are handled — now, instead of always being checked at the player's current location, WorldGuard conditions are checked at the block that the player interacted with, if there is one, and the player's location if there isn't one.
