The 1.64 patch notes are now up on the Camelot Herald, and they are a doosey! Grab a cold drink, a comfortable chair and sit back and read it all at this link, for now here is a snippet:

- In this patch, we have added new bonus types to our dropped items. These bonus types are detailed below. At this time, these features are only available for the classic Camelot dragon loot and Shrouded Isles class-specific epic dungeon armor. - The existing items on classic Camelot dragons have been upgraded with these new bonus types, and new items added to their treasure tables. Please note that a few items were near or at the desired bonus point level, so those few items did not receive any noticeable increases. No bonuses were lowered on any of the existing dragon items.
