Apparently, the recent changes happened so fast (due to Japan and Norway decisions) that they weren't yet incorporated into this release. Hence, the changes in the GB Update will be covered thru the already released Elder's Correspondence and then at upcoming annual Elder's Meeting / Training session, wherein they'll be directed to write things in the margins.
So this tells you just how sudden this "90-day DF'ing, then repentance and let back in" change was.
Sometimes what WT publishes or says in statements is not really how things happen in reality. They "spin" things for public consumption but I doubt they really intend for their "secret manual", which they know is NOT secret any longer, to conflict with the spin they are giving Norway and other European communities that see their violation of Human Rights.
But then , WHY the new revision so soon? They just released the latest edition in October 2023!
