 ** 'comment-indent-function' values may now return a cons to specify a

++++
+** Emacs now supports optional display of line numbers in the buffer.
+This is similar to what linum-mode provides, but much faster and
+doesn't usurp the display margin for the line numbers.  Customize the
+buffer-local variable 'display-line-numbers' to activate this optional
+display.  Alternatively, you can use the `display-line-numbers-mode'
+minor mode or the global `global-display-line-numbers-mode'.  When
+using these modes, customize `display-line-numbers-type' with the same
+value as you would use with `display-line-numbers'.
+
+If `display-line-numbers' is set to t, Emacs will display the number
+of each line before the line.  If set to 'relative', Emacs will
+display the line number relative to the line showing point, with that
+line's number displayed as absolute.  If set to 'visual', Emacs will
+display a relative number for every screen line, i.e. it will count
+screen lines rather than buffer lines.  The default is nil, which
+doesn't display the line numbers.
+
+In 'relative' and 'visual' modes, the variable
+'display-line-numbers-current-absolute' controls what number is
+displayed for the line showing point.  By default, this variable's
+value is t, which means display the absolute line number for the line
+showing point.  Customizing this variable to a nil value will cause
+Emacs to show zero instead, which preserves horizontal space of the
+window in large buffers.
+
+Line numbers are not displayed at all in minibuffer windows and in
+tooltips, as they are not useful there.
+
+The new face 'line-number' is used to display the line numbers.  The
+new face 'line-number-current-line' can be customized to display the
+current line's number differently from all the other line numbers; by
+default these two faces are identical.
+
+You can also customize the new buffer-local variable
+'display-line-numbers-width' to specify a fixed minimal with of the
+area allocated to line-number display.  The default is nil, meaning
+that Emacs will dynamically calculate the area width, enlarging or
+shrinking it as needed.  Setting it to a non-negative integer
+specifies that as the minimal width; selecting a value that is large
+enough to display all line numbers in a buffer will then keep the
+line-number display area of constant width at all times, if that is
+desired.
+
+When using `display-line-numbers-mode', you can customize the variable
+`display-line-numbers-grow-only' to a non-nil value; this means that
+Emacs may grow the above area width dynamically, but never shrink it.
+Under this mode, customizing the variable
+`display-line-numbers-width-start' to a non-nil value will cause Emacs
+to set `display-line-numbers-width' to the minimum width necessary to
+display all line numbers in the current buffer when first visiting it.
+
+Lisp programs can disable line-number display for a particular screen
+line by putting the 'display-line-numbers-disable' text property or
+overlay property on the first character of that screen line.  This is
+intended for add-on packages that need a finer control of the display.
+
+Lisp programs that need to know how much screen estate is used up for
+line-number display in a window can use the new function
+'line-number-display-width'.
+
+Linum mode and all similar packages are henceforth becoming obsolete.
+Users and developers are encouraged to switch to this new feature
+instead.
