 @cindex undo limit
   When the undo information for a buffer becomes too large, Emacs
 discards the oldest undo information from time to time (during garbage
 collection).  You can specify how much undo information to keep by
-setting two variables: @code{undo-limit} and @code{undo-strong-limit}.
-Their values are expressed in units of bytes of space.
+setting three variables: @code{undo-limit}, @code{undo-strong-limit},
+and @code{undo-outer-limit}.  Their values are expressed in units of
+bytes of space.
 
   The variable @code{undo-limit} sets a soft limit: Emacs keeps undo
-data for enough commands to reach this size, and perhaps exceed it, but
-does not keep data for any earlier commands beyond that.  Its default
-value is 20000.  The variable @code{undo-strong-limit} sets a stricter
-limit: the command which pushes the size past this amount is itself
-forgotten.  Its default value is 30000.
-
-  Regardless of the values of those variables, the most recent change is
-never discarded, so there is no danger that garbage collection occurring
-right after an unintentional large change might prevent you from undoing
-it.

+  Regardless of the values of those variables, the most recent change
+is never discarded unless it gets bigger than @code{undo-outer-limit}
+(normally 300,000).  At that point, Emacs asks whether to discard the
+undo information even for the current command.  (You also have the
+option of quitting.)  So there is normally no danger that garbage
+collection occurring right after an unintentional large change might
+prevent you from undoing it.  But if you didn't expect the command
+to create such large undo data, you can get rid of it and prevent
+Emacs from running out of memory.
 
   The reason the @code{undo} command has two keys, @kbd{C-x u} and
 @kbd{C-_}, set up to run it is that it is worthy of a single-character
