 * ![Enhancement][badge-enhancement] `deploydocs` now throws an error if something goes wrong with the Git invocations used to deploy to `gh-pages`. ([#1529][github-1529])
 
+* ![Enhancement][badge-enhancement] In the HTML output, the site name at the top of the sidebar now also links back to the main page of the documentation (just like the logo). ([#1553][github-1553])

 * ![Bugfix][badge-bugfix] A bad `repo` argument to `deploydocs` containing a protocol now throws an error instead of being misinterpreted. ([#1531][github-1531], [#1533][github-1533])
 
 * ![Bugfix][badge-bugfix] SVG images generated by `@example` blocks are now properly scaled to page width by URI-encoding the images, instead of directly embedding the SVG tags into the HTML. ([#1537][github-1537], [#1538][github-1538])
