Here are the patch notes for today’s H1Z1 update

H1Z1, the post-apocalyptic zombie MMO from Daybreak Game Company, has received an update today that, among a number of things, changes the recipe for the backpack frame. That's just one of the changes in today's update. The full patch notes can be read below:

• The backpack frame recipe now requires wood sticks, nails, and metal brackets.
• The framed backpack recipe now requires a backpack frame, a spool of twine, and eight pieces of cloth.
• The spool of twine rate of appearance has been slightly increased.
• Applying an account item to an inventory item no longer resets durability.
• Dropping an item from an inspected container now places the dropped item at the players feet, not the origin of the items container.
• Fixed durability not being attached to projectiles – thrown spears should now be the same durability as when they were your inventory
• Fixed drop spear dupe -you should no longer be able to drop thrown weapons and have them dupe
• Adjustments to "heat" generated while crouched. This will allow players to more effectively sneak around zombies.
• Exiting from a flipped vehicle should no longer send you below the world.
• Vehicles that fall through the world Should now reappear above the world after a small amount of time
• Added a ‘ForceSingleGPU’ option to the [Rendering] section of UserOptions.ini. Adding this option set to 1 will disable the games code adjustments applied when it detects you have more than one GPU active (SLI or Crossfire). This may help some users that are having issues get the game running better without needing to disable their SLI/Crossfire s etups.

Of course, those are the official patch notes. Thanks to the eagle-eyed folk at Reddit, we've got a list of unofficial patch notes that could reveal some future plans. Among the things spotted include a "I Survived PW1" T-shirt which could suggest some sort of major event. You can find all the unofficial notes over at the H1Z1 subreddit.
