+- Update to version 42.0:
+  + Improvements to work better on NVidia cards.
+  + Look in DATADIR for launching environment data files.
+  + PAM updates on exherbo.
+  + Updated translations.
+- Add pkgconfig(gudev-1.0), with minimal version of 232, as a new
+  build requirement.
+- Add explicit update-alternatives to post(un) requirements to
+  avoid rare unexpected behaviors due to package order of
+  installation.
+- Replace systemdsystemunitdir with _unitdir macro. There's no need
+  to manually define it anymore since systemd-rpm-macros already
+  provide it.
