Release Management/Calendar
Note: refer to Release Management Calendar for up-to-date scheduling. This wiki page may not always have the most current information.
Note: B2G releases are explained in B2G Landing
This schedule is based on the current RapidRelease plan. Future dates may change if the process changes. Code is not always released to users on the same day as the branch migration. The release to users may be a few days later, to allow for manual testing and sign-off.
