In the last two weeks I've been busy with making Version 0.2 of Citation.js. Here I'll explain some of the changes and the reasoning behind them. In the past months I've updated Citation.js several times, and the changes included a Node.js program for the commandline and better Wikidata input parsing. While I was working with the "old" code, I noticed some annoying issues in it. One of the biggest things was the internal data format.
