Reverting my previous commit.

Something went horribly wrong when I was doing `hg rebase`.

-:Release: |release|

-
-.. Rules for maintenance:
-
-   * Anyone can add text to this document.  Do not spend very much time
-   on the wording of your changes, because your text will probably
-   get rewritten to some degree.
-
-   * The maintainer will go through Misc/NEWS periodically and add
-   changes; it's therefore more important to add your changes to
-   Misc/NEWS than to this file.
-
-   * This is not a complete list of every single change; completeness
-   is the purpose of Misc/NEWS.  Some changes I consider too small
-   or esoteric to include.  If such a change is added to the text,
-   I'll just remove it.  (This is another reason you shouldn't spend
-   too much time on writing your addition.)
-
-   * If you want to draw your new text to the attention of the
-   maintainer, add 'XXX' to the beginning of the paragraph or
-   section.
-
-   * It's OK to just add a fragmentary note about a change.  For
-   example: "XXX Describe the transmogrify() function added to the
-   socket module."  The maintainer will research the change and
-   write the necessary text.
-
-   * You can comment out your additions if you like, but it's not
-   necessary (especially when a final release is some months away).
-
-   * Credit the author of a patch or bugfix.   Just the name is
-   sufficient; the e-mail address isn't necessary.
-
-   * It's helpful to add the bug/patch number as a comment:
-
-   XXX Describe the transmogrify() function added to the socket
-   module.
-   (Contributed by P.Y. Developer in :issue:`12345`.)
-
-   This saves the maintainer the effort of going through the Mercurial log
-   when researching a change.
-
-This article explains the new features in Python 3.6, compared to 3.5.
-
-For full details, see the :source:`Misc/NEWS` file.
-
-.. note::
-
-   Prerelease users should be aware that this document is currently in draft
-   form. It will be updated substantially as Python 3.6 moves towards release,
-   so it's worth checking back even after reading earlier versions.
