2018-02-22, Version 9.6.1 (Current)

Notable changes:

* events:
  - `events.usingDomains` being set to false by default was removed in
    9.6.0 which was a change in behavior compared to 9.5.0. This
    behavior change has been reverted and the `events` object now has
    `usingDomains` preset to `false`, which is the behavior in 9.x
    prior to 9.6.0 (Myles Borins)
