Effective 7:00pm EST January 31st/12:00am GMT February 1st we will be expanding the world border of the End by 5,000 blocks in all directions.
For the first two days following the End expansion we will have elytra flight disabled throughout the End. This means you will not be able to rocket boost around the End those first two days. This is to give all players a fair chance at finding end cities, shulkers, and elytra. On February 3rd we will re-enable elytra flight, time is TBD.

In addition to the End expansion we are also adding a random warp button to the End as well, this will help with warping you far out in to the end without having to use the end portals.
