http_spew 0.7.0 - modernizing for newer Rubies / 2017-06-12 22:00 UTC

Ruby 2.3+ is now required as kgio dependencies are gone.
This is unlikely to be a problem in practice, as hardly
anybody uses this at the moment.

5 changes since 0.6.0:

      remove most uses of kgio
      make kgio entirely optional
      update to only use public email address
      http_spew: remove kgio require at top level
      gemspec: remove olddoc as a build dependency
