+During the build process, BitBake displays an error on startup if it detects a
+``.bbappend`` file that does not have a corresponding recipe with a matching
+name. To handle these errors, the best practice is to rename the ``.bbappend``
+to match the original recipe version. This also gives you the opportunity to see
+if the ``.bbappend`` is still relevant for the new version of the recipe.
+
+Another method it to use the character ``%`` in the ``.bbappend`` filename. For
+example, to append information to every ``6.*`` minor versions of the recipe
+``someapp``, the ``someapp_6.%.bbappend`` file can be created. This way, an
+error will only be triggered if the ``someapp`` recipe has a major version
+update.
+
+Finally, another method to deal with these errors is to use the variable

-      Defines how BitBake handles situations where an append file
-      (``.bbappend``) has no corresponding recipe file (``.bb``). This
-      condition often occurs when layers get out of sync (e.g. ``oe-core``
-      bumps a recipe version and the old recipe no longer exists and the
-      other layer has not been updated to the new version of the recipe
-      yet).
-
-      The default fatal behavior is safest because it is the sane reaction
-      given something is out of sync. It is important to realize when your
-      changes are no longer being applied.
-
-      You can change the default behavior by setting this variable to "1",
-      "yes", or "true" in your ``local.conf`` file, which is located in the
