2015 09 22 Version 0.16.0

:::info[Historical] This post announced Flow v0.16.0. For current features and behavior, see the Flow documentation. :::

On Friday we released Flow v0.16.0! We had some major perf improvements that we wanted to get into a release, plus let/const support was ready (thanks again @samwgoldman)!

As always, the Changelog is best at summing up the big changes.
