1.14 release notes: A bit more hierarchical organization near end of document
* docs/release-notes/1.14.html (support): New h2 section "Support and Release Planning." (lts-release, svn-1.10-old-stable, svn-1.9-deprecation): Demote from h2 to h3 within #support. (enthusiastic-contributors): The above change makes the final "Enthusiastic Contributors Welcome!" section stand out a bit more. Mention finishing the Shelving and Checkpointing features among the things that people could contribute to.
* docs/release-notes/1.14.html (compatibility-shelving): New subsection, replacing #shelving-transition with much shorter text and links to consolidated shelving section. (experimental): New h2 section to contain all experimental feature and API subsections. (shelving): Promote from h4 to h3 per danielsh's suggestion and place within experimental. Collect all shelving and checkpointing related text here and rearrange for improved flow. (shelving-enabling, shelving-v2, shelving-v3): New h4 subsections within #shelving, to offer more structure to the existing text. (shelving-transition): Move from Compatibility Concerns and demote to h4 within #shelving. Make title explicitly about upgrading 1.10 thru 1.13 shelves per danielsh's suggestion. (shelving-checkpointing): Make this a h4 inside #shelving per danielsh's suggestion. (viewspec-output): Move this section into #experimental.
Suggested by: danielsh (portions; not including the new Experimental Features section; that's entirely my fault :-)
