Changes

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. Thunderbird tracks the [https://www.mozilla.org/en-US/firefox/organizations/ ESR schedule] column schedule per [[Thunderbird:Home#Releases|Thunderbird release info]].
