Security

• Response status must now be an integer greater than or equal to 100.
• Response headers must now be an unfrozen hash.
• Response header keys can no longer include uppercase characters.

• Rack::HTTP_VERSION has been removed and the HTTP_VERSION env setting is no longer set in the CGI and Webrick handlers . (#970, @​jeremyevans)
