I messed up and accidentaly led the team to believe that the feature freeze was on Feb 15.
Because of this most work was planned to be done by Feb 15 and there is no way to finish it by the original
date of Feb 8. To remedy this situation we agreed to add one more beta to the release schedule.
While authoring this document we agreed to pushing off the 4.0.0 release by one week by adding one more RC week (compared to the original plan).
We announced that RC would take 1 month, but then I did the calendar math incorrectly.
This schedule change will give community more time to test the release before we call it done and report any potential regression or unforeseen issues.
