Description

  • feat(stack): Add update-base flag to sync command to rebase onto updated base branch

Implemented a solution to add a new flag (--update-base) for the sync command to rebase onto an updated remote base branch as mentioned in the Issue. Did not alter default behavior so as to not change current behavior.
