[Alan Pater <alan pater gmail com>]

from: http://exiv2.org/whatsnew.html

This release contains a large collection of new features, new lenses
and bugfixes across all areas of Exiv2. See the ChangeLog for the
complete long list of changes.

Both 2013 GSoC projects, 'Web Ready' by Tuan (mentored by Robin) and
'Video Write support' by Mahesh (Abhinav) are included as build
options, the latter builds together with Video Read support, which is
no longer part of the standard build.
