+       * Release 0.31
+       
+        Corrected some unevennesses in when/whether the return values from
+       I18N::LangTags::Detect's various internal functions would be
+       downcased.  Now they're /always/ downcased, and are /always/ fed
+       thru alternate_language_tags()!
+
+       Also, spiffed up and generally improved the earlier test
+       80_all_env.t, which not even I could make sense of, and I wrote
+       the damned thing.  Now it's sane, and checks both scalar and
+       list return values.  Thanks to Rafael Garcia-Suarez and the
+       various CPAN-Testers for prodding me to fix this.  (Hopefully the
+       earlier problems /are/ now fixed!  Otherwise there'll be another
+       version of this module out real soon!)
