Add a new section to inform about what to expect from next release

If there are development notes on [BP Devel](https://bpdevel.wordpress.com), we are now adding a new section that includes a link to the `development-notes/$next-version` category of our blog.

This new feature deserves a new version on the WP Plugins directory.
