0.044     2014-07-16 23:46:09-04:00 America/New_York

    [CHANGED]

    - Providing a custom 'Host' header is now a fatal exception.  Previously, it
      was silently ignored, as the RFC mandates that Host be set from the
      URL, but ignoring it could lead to unexpected, confusing errors.

    - optimized URL splitting

    - Passing 'undef' for any proxy attribute will prevent HTTP::Tiny from
      setting the proxy from the environment.
