I'm planning to send the newsletter on Monday afternoon (UTC), i.e. Monday morning PDT. The existing translations will be posted on the wikis in that language.
There may be a few more edits by Friday, but the existing content should generally remain fairly stable. I (or Gauillaume) will let you know on Friday in any case.
Let me know if you have any questions, comments or concerns. As always, I appreciate your help and feedback
