Trivia

This release contains changes to 221 files, with 16844 insertions and 4010 deletions (diff between two points, does not count multiple changes to the same line). The authorship of the corresponding commits is distributed as shown below; the listing should not be taken too seriously, though, it has just been done using git log --shortstat and summing up the numbers, so it certainly misses details like who originally authored changes which were then back-ported from the master branch (do not fear, you will be correctly attributed when the stats for 2.0 are made).
