Someone posted some small changes over on Theatre Board:
The first act appears to be unmodified from the 2023 production. The second act has some new dialogue in a few spots, I believe: a letter from Martha Plimpton’s character to her daughter Abby, some new dialogue between the Lieutenant and Fritz, and some new lines for Rory Kinnear, I think. But none of those changes felt like more than tweaks — they won’t improve the piece among its detractors nor reduce or increase the appreciation of those like me who are so grateful this work exists.
