The library now supports people.unset(); see https://mixpanel.com/help/reference/javascript-full-api-reference#mixpanel.people.unset for documentation.
NB: If using the embed code "snippet" for your mixpanel installation, please upgrade to the latest snippet to use people.unset() safely.
Other fixes:
- Identify Chrome OS correctly (for $os property)
- Bugfix:
register_once()no longer overwrites previously-registered but falsey values - Stub parts of DOM API when loading in non-browser environments (thanks @gfx)
- Log full "Implementation error" exceptions when DEBUG mode is on
