WordPress 4.9 final nightly build

As noted in the 4.9 release delay post, a final nightly build is now available for testing. This includes three commits, so please take a look through those and test as you can (see #42548, #42530, and #42545).

We hope to ship WordPress 4.9 on Wednesday, November 15th (that’s tomorrow) at 23:00 UTC, but we still need your help to get there. If you haven’t tested 4.9 yet, now is the time!

If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums. We’d love to hear from you! If you’re comfortable writing a reproducible bug report, file one on WordPress Trac, where you can also find a list of known bugs.

We are almost there
But we still need help testing
So test, please and thanks!

Thanks for your continued help testing out the latest versions of WordPress.
