 - Class names to disable [repository links] were misnamed with a suffix of the

-- Docsy statically generates anchor-links after headings using Hugo's
-  [render-heading.html](https://gohugo.io/templates/render-hooks/) hook. This is
-  _potentially_ a breaking change for projects that override the hook.
-
-- The footer layout has been factored into parts: left, right, and center, with
-  copyright a subpart of center. Each part has its own style tag, for example:
-  `td-footer__left`. Note that the style `td-footer__copyright-etc` has been
-  renamed to `td-footer__center`. For details concerning all foot changes, see
-  [#1818].

-- **Footer, copyright notice**:
-  - display of year can now be customized via .Site.Params.copyright.year
-  - title displayed after year must now be given via

+- **Footer copyright**:
+  - The Hugo config option `params.copyright` can be a map with the following
+    optional fields: `authors`, `from_year`, `to_year`. When unset, `to_year`
+    defaults to the year that the site built. The default `authors` is "Site
+    Authors" and is it rendered as markdown.
+  - If `params.copyright` is unset, then the [site `copyright`] option will be
+    used and rendered as markdown, "as is" — with no year is added.
+- Docsy statically generates **anchor links** after headings using Hugo's
+  [render-heading.html](https://gohugo.io/templates/render-hooks/) hook, rather
+  than having them generated dynamically using Anchor.js. Projects that override
+  the heading hook will need to reintegrate the functionality.
