+Layername override implications
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Code can now know which layer a recipe is coming from through the newly added
+:term:`FILE_LAYERNAME` variable and the layer-<layername> override. This is being used
+for enabling QA checks on a per layer basis. For existing code this has the
+side effect that the QA checks will apply to things being bbappended to recipes
+from other layers. Those other layers would need to have patch upstream status
+entries for patches being bbappended for example.

+- Layername functionality available through overrides

+  Code can now know which layer a recipe is coming from through the newly added FILE_LAYERNAME
