+1.7.1:

+
+1.7
+- Updated for v0.2.6_02 and hMod b129.
+- Added option to prevent water from damaging particular blocks
+    (Redstone wire, Minecart tracks, etc.). See disable-water-damage-blocks.
+- /reload WorldGuard should now reload WorldGuard's configuration.
+- Added wg-invincible and wg-amphibious groups that let you give certain
+    players invincibility or underwater breathing.
+- Added the ability to disable fall, water, lava, and/or fire damage.
+- Water/lava bucket blocking should now be more reliable.
+- Added /stack (alias /;) commands to stack items in your inventory into
+    piles up to 64 items in size. Even unstackable items like signs can be
+    stacked.
+- /god mode should now let you gain health.
+- /god mode should now work more reliably.
+- Caught an error message for when the configuration file does not exist.
+
+1.6
+- Added spawn protection that prevents damage when a player spawns.
+- Added login protection that prevents damage when a player joins.
+- Added /god. /god can be used on others, provided that the /godother
+    permission is set for the command's user.
+
+1.5.1
+- Removed the 'java.lang.NoSuchMethodError: Item.setDamage(I)V' error
+    generated.
+
+1.5
+- Removed the block lag fix.
+- WorldGuard now conditionally loads features so you can use any up-to-date
+    build of hMod and the unsupported features won't break the entire
+    plugin. When WG loads, check the server console for a report of
+    features that are not supported by your version of hMod.
+- Changed some configuration defaults:
+    disable-lava-fire=true
+    simulate-sponge=true
+    item-durability=false
+
+1.4.1
+- Fixed issue with the block lag fix dropping item stacks of 0 quantity.
+
+1.4
+- New on-acquire hook. This does both a total inventory check on inventory
+    change and item pick up denial. The item pick up denial is largely
+    thanks to Dinnerbone for fulfilling my request to add a particular hook.
+- Item durability can now be toggled with item-durability. Thanks to
+    Dinnerbone for figuring this out while filfilling my request. The
+    default setting is to fix item durability.
+- New no-physics-gravel and no-physics-sand options allow you to
+    prevent gravel and sand from falling.
+- New allow-portal-anywhere option allows you to create portal blocks
+    anywhere.
