 Changes and New Features in 19.04 (unreleased):
 
+   * ESS[R]: 'ess-get-help-aliases-list' now caches the aliases on the R
+     side.  This should speed up help lookup when the search path has
+     changed and the aliases are read again.
+
+   * ESS: 'ess-command' now uses a default timeout of 1 second.  It
+     should normally be used for instantaneous background tasks since it
+     is synchronous and causes Emacs to block while the command is
+     running.  If the timeout is reached, an error is thrown to avoid
+     hanging Emacs.  An interrupt is sent to the process in case of
+     early exit.
+
+     This is a behaviour change: you will now have to explicitly opt in
+     blocking the whole Emacs UI for more than 2 seconds by supplying a
+     larger timeout (use 'most-positive-fixnum' for infinity).
+
+   * ESS: 'ess-wait-for-process' now returns nil if a timeout is
+     reached.
+
+   * ESS: 'ess-get-words-from-vector' gains a 'timeout' argument.
+
+   * ESS[R]: Fixed performance issue with argument completions.  The
+     help summary for the argument is no longer displayed in the echo
+     area.  This fixes delays and hangs (#1062).
+
+   * ESS[R]: 'ess-command' is now more robust and resilient to hangs and
+     custom prompts (#1043).
+
+   * ESS[R]: 'ess-command' now handles sinked consoles correctly.
+
+   * ESS[R]: 'ess-command' no longer changes '.Last.value'.  As a
+     result, background tasks like completions no longer affect the last
+     value binding (#1058).
+
+   * ESS[R]: Namespaced evaluation is disable in roxygen examples
+     (#1026).  Part of this change is that namespaced evaluation has
+     become a buffer-local rather than process-local setting (#1046).
+     This makes it possible to disable namespaced evaluation in specific
+     buffers or contexts.
+
+   * iESS: Inferior processes can now properly reuse frames (#987).
+     Fixed issue that caused the current buffer to be incorrectly
+     displayed in the new frame when 'display-buffer' is set to pop up
+     frames.
+
+   * ESS[R]: Better support for tramp.  Fixed package evaluation on
+     remote servers with Tramp (#950); process reloading (#1001); and an
+     evaluation issue (#1024).  These fixes were contributed by David
+     Pritchard.
+
    * ESS[R]: Automatic offsetting of R process output is now disabled by
      default because it produces undesirable output in some situations.
      To re-enable, set 'inferior-ess-fix-misaligned-output' to t.
