+Undo branches						*new-undo-branches*
+-------------
+
+Previously there was only one line of undo-redo.  If, after undoing a number
+of changes, a new change was made all the undone changes were lost.  This
+could lead to accidentally losing text.
+
+Vim now makes an undo branch in this situation.  Thus you can go back to the
+text after any change, even if they were undone.  So long as you do not run
+into 'undolevels', undo information is freed up to limit the memory use.
+
+To be able to navigate the undo branches each change is numbered sequentially.
+The commands |g-| and |:earlier| go back in time, to older changes.  The
+commands |g+| and |:later| go forward in time, to newer changes.  
+
+The changes are also timestamped.  Use ":earlier 10m" to go to the text as it
+was about ten minutes earlier.
+
+There is no graphical display of the tree with changes, navigation can be
+quite confusing.
