Neurips 2026: Modified date on reviews [D]

Reviews modified dates are public, and some are recent. I’m a bit confused as to how to interpret this.

In other conferences, reviewers were required to provide a final justification, which would practically force them to modify their reviews during the AC discussion phase lest they get desk rejected.

Here in Neurips I notice that a lot of the high-score reviews do not have a modification past the author discussion phase. I talked with a friend who is an AC today and they told me that adding a final justification is apparently not mandatory and nobody in their batch did it, with people who had anything to add usually doing it in a private comment. They said that any review which has a recent modified date likely got its score updated.

Is that really the case? To any other ACs here: what part of the recently modified reviews in your batch were modified to increase the score?
