+- Remove patch (already upstream):
+  * python-specfile-improve-setup-cfg.patch

+- Update to version 0.12.0:
+  * All classes including `Specfile` itself can now be copied using
+    the standard `copy()` and `deepcopy()` functions from `copy` 
+    module.
+  * `Section.name` attribute has been renamed to a more fitting 
+    `Section.id`.
+  * `setup.cfg` now uses `license_files` instead of deprecated 
+    `license_file`.
