Looking over the changes, overall I'd say that Fei got slightly nerfed. The only thing he really gains off the extra jab frames is a potential combo from a light into sweep, but the spacing for cr.HK is pretty strict since it has ass range. Because st.LP whiffs off a chain on a crouching opponent, I don't see it being a frequently used combo. cl.MP, cr.HK will still be the go-to sweep combo, because it's easily hit-confirmable and an easier link.
The faster start-up for cl.MK means nothing. No one uses cl.MK, since if you're in that range, you might as well be using cl.HP (which has the same start-up, more damage, and is also cancellable).
The lack of invincibility on HK CW is the big loss here, since it's a great tool for avoiding some meaty attacks and throw attempts and leads into his most damaging combos. Now you're pretty much forced to burn meter and accept less damage to get the same result.
