+- bump version 0.3.1, this is a bugfix release.
+  * Bugfixes:
+    - octave/matlab code is distributed fully
+    - negative durations with refined units are minus-signed only
+      once
+    - ddiff is entirely anticommutative now
+    - tests don't fail if zones don't exist on the build system
+    - dseq with empty ranges will no longer produce output (just as
+      seq(1))
+    - arbitrary integers are not interpreted as time anymore
+    - when converting from zone info properly clear zone difference
+      for %Z
+    - dseq(1) will automatically resort to +1mo and +1y iterators
+      for wildcarded ymd dates
+    - dadd(1)'ing ywd dates with output as ymd works properly now
+  * Features:
+    - ddiff can output nanosecond diffs
+    - automatic fix-up of dates is documented now
+    - parser errors and fix ups are reported through return code 2
+    - dseq with no `-f|--format` stays in the calendric system of
+      the start value instead of converting all output to ymd
+  * See info page examples and/or README.
