USD over at NeoGAF did a bang up job translating the latest SSF4: AE dev blog which details some of the changes for a good chunk of the cast. Some of this stuff you might already know, but again it gives us a closer look at some of the subtle and not so subtle changes for each character.
About hitbox improvements and new combos
-cl.LP hitbox is extended foward, making it easier to use, easier to confirm combos
-For example, with the new 7F cr.HK, cr.LK → cl.LP → st.LP or cl.LP → cr.HK (144 damage 210 stun) is now possible
-Depending on the character, cr.LK → cl.LP → st.MP → cr.HK (176 damage 250 stun) is also possible.

About Cosmic Heel's properties
-The block stun on Cosmic Heel is decreased
-The move is still 14F start-up, 5F active as before, but is now -4 when blocked point-blank, +0 when blocked at the tip (down from -1/+3)
-To prevent counters, be aware of the range and hit with the tip
If used from about this distance...
even if it's blocked...
About Big Bang Typhoon (UC2)
-UC2 has different properties
-Damage is now 47 + 21x11 + 23x5 + 27 = 420 (down from 450)
-Mid-air opponents are knocked away when hit, so don't expect any damage
-Since the move is projectile-invincible and has a large vacuum range, try using it as anti-ground

About EX Rekkaken
-EX Rekka's recovery is modified, with the hit and block advantage greatly changed
-1st hit: +2 on hit, +0 on block (improved from -4/-8)
-2nd hit: +0 on hit, -1 on block (improved from -6/-10)
-3rd hit: Down on hit, -23 on block
-Even when the 2nd hit is blocked, Fei is not at a large disadvantage, so we recommend using up to the 2nd hit as much as you like
-Also, because EX Rekka has the same projectile properties as Hadoken, be aware that it won't hit opponents using projectile-invincible moves.

About Juri's hitboxes and hurtbox
-Numerous hitbox and hurtbox changes have been introduced
-st.LP's hitbox is extended forward, and the hurtbox from the elbow to tip has been cut
-cr.LP's hurtbox, which used to reach to the wrist, now is cut down to the elbow
-Since both move's hurtboxes are smaller, they're less likely to be stuffed compared to before
-As for specials, the hurtbox on Kasatsushi (Counter) armor from startup until 3F after has been reduced
About damage changes
-Many normals have modified damage
- j.HP now does 80 (down from 85), B+HP is 60+50 (down from 70+50)
-j.HP → B+HP → LP Yoga Flame now does 228 damage, 320 stun (damage down from 243)
-B+HK is 90 (down from 110), B+LK is now 30 (down from 40)
-Though his damage is lowered, other than the startup changes mentioned in the last blog (cr.MP and EX Yoga Flame), Dhalsim's moves are the same as they were in Super

-Though there's no changes in priority from Super, below is the hitbox for B+HK, frequently used as an anti-air. Dhalsim is invincible around the head area, so keep that mind
Next week is Chun-Li, El Fuerte, Sakura, Cody, Guile, and M.Bison.
