It is so good to see ES moving again, after a decade in the wilderness. EC5 wasn't an aberration, and there are lots of productivity improvements in this and coming in ES7. A big thankyou and congratulations to the people who worked so hard on this. The work of a standardisation committees is often a thankless task.
On a slightly churlish note, the typography / graphic design of the standardisation document is absolutely horrid. From the color choices, to the (many) fonts, to the early 90s type treatment to the fake laid paper texture on the cover to inconsistent spacing inside. Shiver. Okay, superficial, but only slightly so. I genuinely think that type and book design is important for communication.
