I don't think planning with a 6 week freeze period is a good idea. The last releases took longer than 2 months. We could slip the complete release by 2 weeks, of course. In this case I'd move the last posting date to January. So something like: * Last posting date: January 11th, 2019 * Hard code freeze: January 25th, 2019 * Release: March 21st, 2019 Risks for that schedule are: - last posting date short after holiday season - is that really a problem? - Chinese new year rather soon after start of freeze period - planned release date rather close to eastern Opinions?
