 .. Fixes for situations where bzr would previously crash or give incorrect
    or undesirable results.
 
+* ``bzr branch`` now fetches revisions when branching into an empty
+  control directory. (Jelmer Vernooij, #905594)
+
 * Support scripts that don't call bzrlib.initialize() but still call run_bzr().
