+We have reworked the Prettify Symbols mode to support only the default
+@code{prettify-symbols-compose-predicate}. No need to consider
+whether your major or minor mode needs its own prettifications; just
+use what came with Emacs. We also removed the
+@code{prettify-symbols-unprettify-at-point} option: once prettified,
+always prettified! These changes make the Prettify Symbols mode quite
+a lot simpler and easier to use.

+Support for nifty new features of xterm, such as access to the X
+selection and the clipboard, the ``bracketed paste mode'', and other
+advanced capabilities has been removed. When you kill text in an
+xterm Emacs session, that text is only saved in the Emacs kill ring,
+without letting other applications have any way of accessing it. An
+xterm is just a text terminal, nothing more, nothing less. There
+should be no feature we support on xterm that isn't supported on bare
+console terminals. For the same reasons, support for mouse-tracking
+on xterm was removed. We will continue this line of simplifications
+as we downgrade to previous versions of Emacs; stay tuned.

+Various features in @file{package.el} have been simplified. The
+``external'' package status is no longer available. A package present
+on multiple archives will now be listed as many times as it is found:
+we don't believe in concealing any information from the users. This
+and other similar simplifications made
+@code{package-menu-toggle-hiding} unnecessary, since there's nothing
+to unhide now.

+The @kbd{@key{UP}} and @kbd{@key{DOWN}} keys in the minibuffer have
+been simplified to move by history items. No need to wonder whether
+you have moved to the next/previous item or to another line within the
+same item. Well-written commands shouldn't allow too long history
+entries anyway; be sure to report any that do as bugs, so that we
+could fix them in past versions of Emacs.

+The VC mode was simplified by removing the support for ``push''
+commands. Moving back in time means you will have less and less need
+to use modern version control systems such as Git, Bazaar, and
+Mercurial, so the necessity of using ``push'' commands will gradually
+disappear. We removed it from Emacs in advance, so that you won't
+need to un-learn it when this command disappears, as it should.

+The support for full C/C++ expressions in macros has been removed from
+Hide-Ifdef mode. It now supports only the basic literal macros. As
+result, the user interface was simplified, and a number of useless
+commands have been removed from Hide-Ifdef mode. Further
+simplifications were made possible by removing support for some fancy
+new preprocessor directives, such as @code{#if defined}, @code{#elif},
+etc.
