Author: gjb Date: Mon Feb 2 21:09:26 2015 New Revision: 278116 URL: https://svnweb.freebsd.org/changeset/base/278116 Log: Overhaul the relnotes page to reorganize the sections. With the previous layout, the majority of the release notes were categorized under one main "What's New" section, which in addition to making the page difficult to parse relevant bits, also had a few rendering issues, such as 'Note' blocks visually not appearing as if they pertain to a particular change. This change removes the "What's New" section, integrating it with the introduction. In addition, each section now provides a brief description of its contents, broken down further into a subsection for each "topic", making it much easier to find a specific topic in the page.
