To better help everyone understand the data changes in 2013e, I've run a tool to analyse them and produce nice coloured git diffs. Changes from 2013d to 2013e https://github.com/jodastephen/tzdiff/commit/57aac13605f184a46f74d22f7dddc90... Lines in green are new added data, lines in red are deletions.
From a purely data perspective, the majority of 2013e changes are LMT based. The largest change is to McMurdo/South_Pole.
