 ------
 
+.. warning:: New content packs were built for this release (July 2017). Users of
+  non-English content packs should upgrade both the content packs and the videos. For the
+  English content update, there are 396 new videos to be downloaded.
+
+  If you are using only English contents, you have the option to stay with
+  previously downloaded content packs, provided that you use an installer that does not
+  bundle the English content pack (Debian/Ubuntu packages or `pip`).
+
+  If you are downloading videos from torrent (see: :ref:`bulk-video-downloads`), you
+  should re-use the target directory of your previously downloaded videos, then only
+  396 videos need to be downloaded.
