Hi all,

Sending a short and hopefully sweet update:

 * We're still on schedule for Jan 15th 2019.
 * We'll be starting around 15:00 (3pm) UTC time. The release procedure itself 
could take an hour or two, depending on how much caffeine I have in my system.

You're all welcome to follow the fun on the dev Gitter [1] but please don't 
post so the development team can do its job. Various expressions of excitement 
can take place in the lobby [2] or IRL if you're into that sort of thing.

- Igno
