Turf has undergone a major refactor. The main improvements are:
Dependencies like lodash and async.js have been removed.
Every turf function has been broken into its own seperate module, so you can install what you need and nothing else.
Turf has passed ownership from my personal github account to a community account, Turfjs, to allow for better collaboration between contributors.
Interfaces have been switched from async to sync. Turf does not deal with io, so sync interfaces are easier to use, with no downsides.
This release has been a multi-month process, and represents an effort to make turf work better in resource constained environments and in the browser. Turf's main goal has always been to make a geo stats engine that is easy to install and easy to use, and I think this goes a long way towards that objective.
As always, feature requests are welcome, so drop us a line if you have an idea for use case for a new feature.
Special thanks to the many contributors to this push, especially @tmcw and @adamdrago.
