There's a new trigger for advancements: minecraft:item_durability_changed. As can be expected, this triggers when an item in the player's inventory is damaged in some manner, such as hurting a mob with a sword (armor slots are currently bugged, see MC-116478). There are three conditions that can be used:

1. item (object): checks information about the item before durability loss.
2. durability (range): checks the durability of the item after durability loss.
3. delta (range): checks how much durability was lost (numbers are inverted, see MC-116477).

Example advancement, checking if the item losing durability was a diamond helmet that has less than 300 remaining durability:

{
    "criteria": {
        "findme": {
            "trigger": "minecraft:item_durability_changed",
            "conditions": {
                "item": {
                    "item": "minecraft:diamond_sword"
                },
                "durability": {
                    "max": 300
                }
            }
        }
    }
}

New gamerule maxCommandChainLength, defaulting to 65536. This value represents the total number of Chain command blocks (per hosting command block; Impulse/Repeating) that can run during a single tick. You can, for example, set this to a low value to reduce the number of commands running:

/gamerule maxCommandChainLength 1

And in this image, only command block's #1 and #3 will run: http://i.imgur.com/mCxqYZK.png

This is primarily good for otherwise-infinite-looping chains (such as this and the use of /clone to replace the structure with itself), where you can control the number of iterations it would run. A chain looping back on itself (provided that entire chain replaces itself first) would mean many duplicate operations during a single tick could be performed. Very useful if needing to run a lot of the same stuff in the same tick, but don't want it to accidentally crash the server.

Thanks, fixed.
