Microsoft's Windows Insider team held its monthly webcast today, and this month's focus was Sticky Notes. In fact, it was the first Insider webcast to be recorded outside of the U.S., as it was in Vancouver, Canada. Of course, someone asked if there would be any Windows Insider builds this week, to which Brandon LeBlanc replied that there will not be.
It's not really a surprise, since Thursday is Thanksgiving in the United States. Many people at the firm are taking the week off, given that it's already shortened.
Typically, new Windows 10 Insider Preview builds arrive on Wednesdays; in fact, every 19H1 build to arrive in the Fast ring has been on a Wednesday. So in case you were planning on sitting in front of your Fast ring machine tomorrow at 10am Pacific Time and checking for updates, don't bother.
Presumably, the team will be back on its regular schedule next week, so perhaps we'll see a new build on November 28.
