** Whitespace

---
*** 'whitespace-cleanup' now adds missing newline at end of file.
If 'whitespace-style' includes 'missing-newline-at-eof (which is the
default), the 'whitespace-cleanup' function will now add the newline.

** Eshell

---
*** New option 'eshell-command-async-buffer'.
This option lets you tell 'eshell-command' how to respond if its output
buffer is already in use by another invocation of 'eshell-command', much
like 'async-shell-command-buffer' does for 'shell-command'.  By default,
this will prompt for confirmation before creating a new buffer when
necessary.  To restore the previous behavior, set this option to
'confirm-kill-process'.

** SHR

+++
*** SHR now slices large images into rows.
Sliced images allow for more intuitive scrolling up/down by letting you
scroll past each slice, instead of jumping past the entire image.
Previously, SHR sliced images when zoomed to their original size, no
matter how large or small that was).  Now, SHR slices any images taller
than 'shr-sliced-image-height'.  For more information, see the "(eww)
Advanced" node in the EWW manual.

---
*** You can now customize the image zoom levels to cycle through.
By customizing 'shr-image-zoom-levels', you can change the list of zoom
levels that SHR cycles through when calling 'shr-zoom-image'.

*** Support interactive D-Bus authorization
A new ':authorization t' parameter has been added to 'dbus-call-method'

authorize the invoked D-Bus method (e.g., via polkit).

\f
* Changes in Emacs 31.1 on Non-Free Operating Systems

---
** Process execution has been optimized on Android.
The run-time performance of subprocesses on recent Android releases
where a userspace executable loader is required has been optimized on
systems featuring Linux 3.5.0 and above.
