I think wikipedia would be the most reliable and informative source on TIFF format.

IIRC 3 approvals is "enough" and don't remember if need to wait for someone to merge. Since change is trivial and could green up other PRs, I will use my super power of pressing a green button. Thanks everyone for speedy reaction!

just fyi: technically, the opening of a release PR (as was recently done by @franklin-feingold : #1004) "freezes" the spec and no PRs (except critical bugfixes) should be merged until the release PR is merged (after 5 days) and the release completed. That's to make any potential final reviews easier and to avoid confusion.

I just rebased the release PR on the merged changes from here and force-pushed, so it should be fine.

EDIT: Also, any PRs that are merged now (and not followed by a rebased+force-push on the release branch) will not show up on the changelog, due to the way we set things up
