The May update is here after only two days of waiting! There is a new defense called the Air Sweeper (more information tonight) unlocked at TH6. Read all of the changes here:

New anti-air defense: The Air Sweeper

• Push back groups of flying enemies with strong blasts of air
• Air Sweepers deal no damage, but are great at slowing the progress of air attacks
• Air Sweepers can only face one way, but can be rotated to a direction of your choosing
• Unlocked at Town Hall 6, Air Sweepers gain more pushing strength when upgraded

Clan bookmarks

• Bookmark any Clan for later viewing using the ‘+’ icon on any Clan profile page
• You can bookmark up to 30 Clans and view them under a new tab next to your profile

Clan War attack army preview

• Never attack unprepared again! Your army is now previewed before every war attack
• Inspect your troops, Clan troops, spells and heroes – anything missing will be flagged red
• Be ready or be sorry! You can no longer end war attacks early without surrendering

Interface improvements

• Starting at Town Hall 5, a one-time name change will become available in the game settings – use it wisely!
• Clan chat now shows when Clan settings are changed, indicating who changed them
• Defense ranges can now be seen even when the defense is under construction
• Defense modes can now be changed even when the defense is under construction
• Defensive buildings now initially point away from the TH in combat, EXCEPT for the Air Sweeper, which always points in its configured direction

Gameplay improvements

• Attacking troops will not start chasing defending troops as far away as they used to
• Fixed a very rare case where a defense might target a troop at the edge of its range, but not fire
• Loot values for many lower level single player maps have been improved, along with some slight layout tweaks and surprises

So that is the whole list of the update features! There are some major changes in this game including a confirm attack button:

Also, the new defense; the Air Sweeper, will completely change the way air attacks are done. You will see a guide completely outlining this tonight. All in all, the May update was some necessary changes and fixes. Read more about the may update in the coming days.
