Please ensure you have:
  1. incremented rc count or version in the repository :
     - in libraries/Config.class.php PMA_Config::__constructor() the line
          " \$this->set( 'PMA_VERSION', '$version' ); "
     - in Documentation.html the 2 lines
          " <title>phpMyAdmin $version - Documentation</title> "
          " <h1>phpMyAdmin $version Documentation</h1> "
     - in translators.html
     - in README
  2. checked that all language files are valid (use
     the "./scripts/check_lang.php" script to do it).

Continue (y/n)?

Todo now:
---------

1. If not already done, tag the repository with the new revision number
   for a plain release or a release candidate:
    version 2.7.0 gets two tags: RELEASE_2_7_0 and STABLE
    version 2.7.1-rc1 gets RELEASE_2_7_1RC1 and TESTING

 2. prepare a release/phpMyAdmin-$version-notes.html explaining in short the goal of
    this release and paste into it the ChangeLog for this release
 3. upload the files to SF, you can use scripts/upload-release, eg.:

        ./scripts/upload-release \$USER $version release
 4. add SF news item to phpMyAdmin project
 5. announce release on freshmeat (http://freshmeat.net/projects/phpmyadmin/)
 6. send a short mail (with list of major changes) to
        phpmyadmin-devel@lists.sourceforge.net
        phpmyadmin-news@lists.sourceforge.net
        phpmyadmin-users@lists.sourceforge.net

    Don't forget to update the Description section in the announcement,
    based on Documentation.html.

 7. increment rc count or version in the repository :
        - in libraries/Config.class.php PMA_Config::__constructor() the line
              " \$this->set( 'PMA_VERSION', '2.7.1-dev' ); "
        - in Documentation.html the 2 lines
              " <title>phpMyAdmin 2.2.2-rc1 - Documentation</title> "
              " <h1>phpMyAdmin 2.2.2-rc1 Documentation</h1> "
        - in translators.html

 8. add a group for bug tracking this new version, at
    https://sourceforge.net/tracker/admin/index.php?group_id=23067&atid=377408&add_group=1

 9. the end :-)
