Improvement

• Added support for "Changelog" link in RubyGems.org page.

  • GH-30
  • Patch by Mark Young

• Dropped ObjectSpace._id2ref dependency because
  ObjectSpace._id2ref is deprecated. Drb::WeakIdConv is
  meaningless by this. So it's deprecated. Use the default ID
  converter instead.

  • GH-35
  • https://bugs.ruby-lang.org/issues/15711

Fixes

• SSL: Fixed wrong certificate version.
  • GH-29

Thanks
