Java Edition 1.9

, known as The Combat Update, is an upcoming update to Minecraft with no set release date. Dinnerbone has stated that many of the features he has shown for 1.9 are not “100% final”, so things may change later. Dinnerbone also stated that snapshots will be starting 'soon', and at the Minecon "Behind the Scenes" panel, Searge said that snapshots will begin as soon as the new combat mechanics have been implemented, which might be in 1-2 weeks. Later on July 14, 2015, Dinnerbone hinted that there may be a snapshot next week.
