Changes for version 1.57 - 2013-08-16
- Make internals a little less quirky.
- Stop returning explicit undef for browser_string and os_string. (Why would you ever call these in list context?)
- Return name of robot for browser_name when browser is, in fact, a bot. Previous behaviour was to return undef or something just really wrong.
- HTTP::BrowserDetect - Determine Web browser, version, and platform from an HTTP user agent string
