+----------

+* Replace all references to ``taskgraph.files_changed``. Instead, use one of:
+
+  * The ``files_changed`` parameter
+  * The ``get_files_changed`` method on an instance of ``taskgraph.util.vcs.Repository``
+  * Mercurial repositories relying on hgmo's ``json-automationrelevance``
+    endpoint will need to in-line this logic into their own custom Taskgraph
+    logic
+* In tasks using the ``from_deps`` transforms, remove ``from-deps.set-name`` if
+  it is set to ``true``
+* Update any references to pull request cached task indexes from
+  ``{cache_prefix}.cache.head.{head_ref}...`` to ``{cache_prefix}.cache.pr...``
+  (i.e, add ``pr`` and remove the ``head.{head_ref}``)
