+- Update to 1.5.3
+  + Fix edge cases involving dequoting zero-length tuples that can lead to a
+    buffer overflow under the right circumstances.  Thanks to A. Wilcox for
+    reporting and supplying a patch. (boo#1105438 - CVE-2018-1000221) 
+  + Ensure environment variables override values learned from personality files
+    or built-in defaults.
+  + Add pkgconf-personality(5) manpage documenting the personality file format.
+- Drop BR pkgconfig and manually specified pkgconfig() Provides for
+  devel subpackage to avoid dependency loops.
