This is a page for tracking in-progress releases. For maintenance releases, we use a general checklist to ensure we don't miss anything.
- perhaps you'd like to see who release drivers for various releases are?
- or perhaps you'd like to learn more about the priority rankings we assign to releases?
- you might even wonder how we use flags to manage our releases?
- or what branches exist and when they branched?
- perchance you're confused about update terminology?
- maybe you'd like to know about our various branch support levels?
- perhaps you want to see the RapidRelease Calendar for future aurora merges, beta merges, and releases?
- maybe you are interested in checking the Feature Release Tracker for upcoming features?
Upcoming Releases
Please do not edit scheduled dates if you are not a release driver.
Note: the Beta, Aurora and Nightly dates are code merge dates, not release dates.
