10 % Changelog
11 %
12 % 1.2 (Nov 3, 2016)
13 % - It's been a while :) Integrated a patch submitted by Jan Strunk <jan.strunk@uni-koeln.de>
14 % (thanks a lot Jan!) fixing a bug with the behavior of "edge end x offset".
15 %
16 % 1.1 (Jan 17, 2012)
17 % - Added the possibility to use simple arcs as edges (keys: arc edge/segmented edge)
18 % - Added "edge start x offset" and "edge end x offset" to fine tune edge start/end point position
19 % - Added \depstyle to define styles more easily
20 % - Added "simple" theme, based on the parse on page 1 of [Nivre and McDonald, 2008 ACL-HLT]
21 % - Added instructions to draw bubble parses
22 % - Fixed bug that would cause groupedges not to be straight under some circumstances;
23 %
24 % 1.0 (Nov 26, 2011)
25 % - First public release
