Test failures are a 404 in the read_epw_remote test. Seems like the same thing as this: NREL/EnergyPlus#9036, see my comment in that thread. Might want to xfail that test depending on what they say.

Sphinx output looks fine to me. There is some log noise about deprecated functions but I don't think there's any action needed there.

Ok @mikofski's url works, someone else merge this if they're good with that change

[wholmgren]

Kevin do you want to tag too?

[mikofski]

Shall I send out announcements? Unfortunately too late for NF August newsletter, but I'll let them know for September. Let me know if there's anything from the release notes that you want me to highlight.

[mikofski]

I'll do announcements a little later today. Thanks Kevin, Will, Cliff, Adam, Anton, and everyone who contributed new and previously :)
