Changesets
Work in changesets that keep their identity as they evolve, so history stays readable and every change can be reviewed on its own.
Stacks
Build a feature as a stack of small, dependent changesets and land them in order without rebase gymnastics.
Review
Review each changeset in context, compare versions of a change after an update, and restore an earlier version when needed.
Inbox
One place for the changes that wait on you: reviews to give, feedback to answer and stacks ready to land.
