** Fixed bugs

*** Infinite recursion under prettify-symbols-mode and linum-mode.
Apply a fix for Bug#27761.

*** Crash when resizing a frame too small by mouse dragging.

*** Can't resize a frame by dragging on macOS 10.13 Beta via Screen
Sharing.app.

** Improvements

*** The fancy splash screen look vibrant on OS X 10.10 and later.
For non-Retina display users, it is recommended to replace
etc/images/splash.png with the alpha-channeled version:

This effect can be turned off with "Reduce translucency" in the
Accessibility pane of the System Preferences.

*** On OS X 10.10 and later, if the frame background color is light,
then scroll bars look slightly translucent.
This effect can be turned off with "Reduce translucency" in the
Accessibility pane of the System Preferences.

*** On OS X 10.10 and later, if the frame background color is dark,
then the title bar, the tool bar, (the tab bar on macOS 10.12), scroll
bars, and popup menus look also dark.
The title/tool/tab bars have already looked translucent on macOS 10.12
regardless of the frame background color types.  Text smoothing in
these bars for the focused frame seems to be problematic if the
contents contain Core Animation layers that use Core Image filters
especially with dark window background colors and non-Retina displays.
A change in the last version with respect to window/view hierarchy
manifested this problem, and the use of dark bars works around it.

*** Magnify and rotate events now contain the :phase property.
Now absence of the :phase property in a magnify event means it is a
"smart magnify" event rather than what is caused by a pinch gesture.
On OS X 10.10 and later, its value is either `began', `changed', or
`ended'.  On earlier versions, it is always `none'.

*** New function mac-send-action that sends the specified Cocoa action
using the responder chain for action messages.
Some useful examples Cocoa actions are `zoom', `hide', `unhide',
`activate', `hideOtherApplications', `unhideAllApplications', and
`orderFrontCharacterPalette'.

*** New function mac-frame-tab-group-property to set tab group
properties.

*** New menu items (mostly in the "Buffers" menu), key bindings
(Control-Tab, Control-Shift-Tab) for tabbing on macOS 10.12 and later.

*** On macOS 10.13 Beta, the pinch close gesture triggers tab group
overview.  If you want to make the text size smaller, first pinch open
and then pinch close without releasing the fingers from the trackpad.
Alternatively, remap the corresponding command as:
  (global-set-key [remap mac-magnify-text-scale-or-overview-tab-group]
                  'mac-magnify-text-scale)
