The proposed changes to the Crane Wing feat don't make any sense. It states to change the first two sentences of the benefit to the updated text but it still mentions a deflected attack... See below:
Before:
Benefit: Once per round while using Crane Style, when you have at least one hand free and are either fighting defensively or using the total defense action, you can deflect one melee weapon attack that would normally hit you. You expend no action to deflect the attack, but you must be aware of it and not flat-footed. An attack so deflected deals no damage to you.
After:
Benefit: When fighting defensively with at least one hand free, you gain a +4 dodge bonus to AC against melee attacks. If a melee attack misses you by 4 or less, you lose this dodge bonus until the beginning of your next turn. An attack so deflected deals no damage to you.
I'm sure the text in the errata should just say to replace all the text for the benefit to the updated information.
