2016-02-22, Version 4.4.0 'Argon' (LTS)

In December we announced that we would be doing a minor release in
order to get a number of voted on SEMVER-MINOR changes into LTS.
Our ability to release this was delayed due to the unforeseen security
release v4.3. We are quickly bumping to v4.4 in order to bring you the
features that we had committed to releasing.

Notable changes:

  * **deps**:
    - An update to v8 that introduces a new flag
