Adds information about changes in the current release, links to changlogs from
previous releases, and improves links to use `https`.
Release date for the latest versions will be August 18 even in the event of a
delayed core release. Since all themes are backwards compatible we don't have
a dependency there.
Props mercime, davidakennedy.
