+** The old bindings C-M-delete and C-M-backspace have been deleted,

+** New minor mode, Visible mode, toggles invisibility in the current buffer.
 When enabled, it makes all invisible text visible.  When disabled, it
 restores the previous value of `buffer-invisibility-spec'.

+** The new macro dynamic-completion-table supports using functions
+as a dynamic completion table.
+
+  (dynamic-completion-table FUN)
+
+FUN is called with one argument, the string for which completion is required,
+and it should return an alist containing all the intended possible
+completions. This alist may be a full list of possible completions so that FUN
+can ignore the value of its argument. If completion is performed in the
+minibuffer, FUN will be called in the buffer from which the minibuffer was
+entered. dynamic-completion-table then computes the completion.
+
+** The new macro lazy-completion-table initializes a variable
+as a lazy completion table.
+
+  (lazy-completion-table VAR FUN &rest ARGS)
+
+If the completion table VAR is used for the first time (e.g., by passing VAR
+as an argument to `try-completion'), the function FUN is called with arguments
+ARGS. FUN must return the completion table that will be stored in VAR. If
+completion is requested in the minibuffer, FUN will be called in the buffer
+from which the minibuffer was entered. The return value of
+`lazy-completion-table' must be used to initialize the value of VAR.
