The Championship Mode patch for Street Fighter 4 not only added new features for match making and rankings, but it also tweaked a few of the character's moves.• Fei Long's Hard Flying Kick (Chicken Wing) now has more start up frames of animation and some invincible frames you can use it to go through projectiles. The new start up time stops him from doing his combo loop.
• (Jury seems to be split on if this change was made or not) The hitboxes on Zangief's Lariat have been altered. Medium and smaller characters, including the Shotokans, should be able to crouch and sweep Gief now after he's completed his first turn. The offset to this is the hittable box while he's performing a Lariat is a little smaller.
