"Dear Old Shiz Reprise" was cut. I think because they changed Dr. Dillamond's fate.
"We Deserve Each Other Reprise" was changed to "The Wicked Witch of the East". They no longer mention Elphaba's time at the Badlands.
Some of the reprises are still in the show, they just aren't listed. Like "The Wizard and I Reprise" is currently more like "The Wizard and I/Something Bad Reprise". "A Sentimental Man" has a reprise in the show still.
"No One Mourns the Wicked Reprise" was added before "Thank Goodness" in the current version. They changed some dialogue in "Thank Goodness" between Glinda and Fiyero.
"No Good Deed" had a section taken out. The part where Elphaba belts "Unlimited..."
I think in "For Good" , the lyric used to be "Like a ship blown from its course" but now it's "Like a ship blown from its mooring".
"Which Way's the Party" is exactly like "Dancing Through Life" in terms of trying to get across what Fiyero's character's beliefs are including the dialogue, what happens, "We Deserve Each Other" sequence. I think the only reason they changed the song's theme was so the horrible twirling made sense.
"The Wizard and I" - "But I'll be too busy to think about that as my Wizardly duties pile high..." was changed to " And this gift or this curse I have inside, maybe at last I'll know why..."
Fellow Ozians. Friends. We've been through a frightening time and there will be other times and other things that frighten us. So if you'll let me, I'd like to try to help, I'd like to try to be . . . Glinda the Good.
