In this release issues with timezones were fixed (#3) and most of the custom, manual parsing code was replaced with ICAL.js, an open-source ICAL parsing library for JavaScript. Dependencies on Moment.js were removed and there are no longer dependencies on any external libraries (meaning that all code - even ICAL.js - is contained in the project).
