+Backward compatibility notes
+----------------------------
+
+In the next major release, we will change the behaviour of the "git
+push" command. When "git push [$there]" does not say what to push, we
+have used the traditional "matching" semantics (all your branches were
+sent to the remote as long as there already are branches of the same
+name over there). We will use the "simple" semantics, that pushes the
+current branch to the branch with the same name only when the current
+branch is set to integrate with that remote branch. There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable.
