Newer browser detection and better SDK-loading from relative URLs

Automatic browser and OS detection has been updated for:

• IE mobile
• MS Edge
• Windows Phone
• Opera 30+

Loading the library with the embed code (snippet) now works in all browsers via relative URL.

time_event and local snippet support

• time_event allows timing the duration until a certain event is tracked
• loading the lib via the embed code (snippet) now works in HTML files loaded from the local filesystem

Track browser url automatically, expose info properties

Current url will be set automatically as string super property $current_url. Super properties are now exposed through mixpanel._.info.properties.

Track browser version automatically

Browser version will be set automatically as a numeric super-property $browser_version, including major and minor version (e.g., 11.1).

localStorage support

Adds a new config option to use localStorage instead of cookies to persist user data in the browser:

mixpanel.init(TOKEN, {persistence: 'localStorage'});

If a cookie with the same name exists, it will be removed and its data transferred to the new localStorage entry.

The old config options cookie_name and disable_cookie are now aliased to persistence_name and disable_persistence.

Eliminate undocumented token override in track()

This behavior was undocumented, and also broken in the minified version for a long time. It is hereby eliminated.

To track to multiple Mixpanel projects on a single page, initialize separate lib instances with mixpanel.init(token, options, instance_name).

Bugfix for minification issue

A bug in 2.4.0 could cause minified versions of the library not to track if certain property names were set. This release fixes that issue.
