+  pkgcheck-action).
+
+- EclassCheck: force bash error output to use the C locale.
+
+- Officially export Result class in addition to all specific result
+  keywords/classes for API usage which can be useful for type
+  hinting purposes.
+

+  keywords to the default set (via '+Keyword') that trigger exit

+  well.
+
+- PackageUpdatesCheck: Use search repo to find old packages to fix
+  checking for OldPackageUpdate results in overlays.
+
+- Make 'NonsolvableDeps' a scannable keyword alias.

   warning to style level.
