Thank you. The most recent completely new information from the Snowden files is found in Jacob Appelbaum's 2022 thesis[1], in which he revealed information that had not been previously public (not found on any previously published documents and so on). And AFAIK, the most recent new information from the published documents (along with this post) might actually be in our other posts[2], but there might be some others we aren't aware of.
