+The Jinja2 package has been renamed to `Jinja`_. This package provides
+compatibility while projects transition to the new name. Imports from
+``jinja2`` will be redirected to ``jinja`` and a deprecation warning
+will be emitted.
+
+Projects are advised to require 'Jinja' instead of 'Jinja2' and replace
+all imports of ``jinja2`` with ``jinja`` to continue receiving updates.
