They don't change our view on him at all. The redactions are mostly concerned with a very fine points regarding the history of the H-bomb and Oppenheimer's role in arguing for using tactical nukes in Europe. Both of these things were classified at the time (1954) but have been declassified for a long time now. Which is why the DOE had no problem declassifying them in full. The redactions do not shed any new light on Oppenheimer, in other words, because all of that information had already been released in other forms by, say, the early 1990s.

What they do tell us a lot about is the classification situation in 1954, and what the US was afraid of the Soviets knowing. It also sheds some light on the conduct of the hearings themselves, and what happened when they went from being "strictly confidential" (with witnesses speaking sometimes very freely) to being a matter of public record (which resulted in the deletion of a few things that weren't classified but were kind of politically problematic).

But from what I have seen, nothing was deleted that drastically would change how people evaluated Oppenheimer even at the time. They are careful deletions and the censor, Dr. James Beckerley, was no pro-secrecy nut (he in fact resigned from the job a few weeks later and became a critic of atomic secrecy).

The only point which might have been useful for public evaluation of Oppenheimer is his role with regards to the deployment of tactical weapons in Europe. This might have made him look a little less "dove" than people realized, and emphasize that his alternative to building the H-bomb wasn't building no bombs, but building lots of little tactical nukes. We have known about Oppenheimer's work in this area for a long while now, though, so it doesn't come as a modern revelation. But it was less known in 1954.

Full disclosure: I am quoted (very briefly) at the very end of the article, and feel it somewhat obscures my role in all of this (I am the one who found where these transcripts had been misplaced, 6 years ago, and got the process of declassification started through a FOIA request). I have had private copies of 17 of the 25 volumes since 2008, and a lot of time to think about those ones. I was surprised that the DOE posted the whole thing on their website last week without informing me first. (Both my DOE and NARA contacts have apologized for how things went down; it seems like one hand didn't know what the other hand was doing.) Anyway, I am writing up an article on the whole affair, including a detailed discussion of what the disclosures do and don't say, that I am hoping to get out the door next week. You can check out my Twitter feed if you want more details about the whole thing, as well as full-color photos of the actual pages from the transcript as I saw them in 2008, with the red pencil of the censor (JB = James Beckerley) removing the passages in question.
