0.9703 2015-09-29  Jarkko Hietaniemi  <jhi@iki.fi>
    - document (at user level) the openbsd random problem
    - using the 5.22+ Inf was done the wrong way:
      https://github.com/neilbowers/Graph/issues/1

0.9702 2015-09-28  Jarkko Hietaniemi  <jhi@iki.fi>
    - rt.cpan.org 107394 $Storable::VERSION may contain underscores
    - follow-up to rt.cpan.org 104687: more docs, fixes, and tests for
      diameter/radius/shortest_path/center_vertices/vertex_eccentricity
      for corner cases like empty graph, single-vertex graphs, and
      in general unconnected graphs
    - for perl 5.22 or later one should be able to use Inf for Infinity
    - openbsd before perl 5.20 had nondeterministic rand()

0.96_01 2014-03-09 @NEILB
    - Taken over maintenance from JHI
    - Specified min perl version 5.6.0
    - Tweaked COPYRIGHT and LICENSE in pod to match usual form
    - Added "use warnings", but that results in loads of warnings
      about functions redefined. So added "no warnings 'redefine';".
      Have to come back and work that one out!
    - Set all VERSION's to 0.96_01. I suspect a switch to Dist::Zilla
      might be coming soon...
    - Updated README to acknowledge change in maintainer
    - Reformatted as per CPAN::Changes::Spec
