Ultimately it doesn't change the fact that "all users must upgrade" as said in the announce, but I need to judge the urgency of the upgrade, so having a rationale is extremely useful. If backported commits fix something obvious then there's nothing to add, but in this case I believe I'm not the only one who'd puzzle over it (if someone is actually looking...) Thanks! -- Dominique Martinet
