Yeah, Matthew, what’s the ETA? stares at the email with the text awaiting review 
It’s in progress. I did the bulk of the writing before break with some touch-ups after coming back, now it has to go through the multi-phase preparation for release: verifying text with our development team for accuracy and tone (it’s here now), review with our editorial team for grammar and polish, delivery to our localization teams to be translated into all our supported languages, and then re-distributed to all our regional community managers for formatting and publishing. There’s also asset creation and review that happens in tandem, for things like headers and thumbnails or any in-blog images, all which follow a similar structure.
Barring any unforeseen circumstances, it should publish before the release of the 2.6.8 PTR.
