[3.0.0] - Unreleased

Security

• Do not use semicolon as GET parameter separator. (#1733, [@​jeremyevans])

SPEC Changes

• 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.
• Response header values can be an Array to handle multiple values (and no longer supports \n encoded headers).
• Response body can now respond to #call (streaming body) instead of #each (enumerable body), for the equivalent of response hijacking in previous versions.
• Middleware must no longer call #each on the body, but they can call #to_ary on the body if it responds to #to_ary.
• rack.input is no longer required to be rewindable.
• rack.multithread/rack.multiprocess/rack.run_once are no longer required environment keys.
• SERVER_PROTOCOL is now a required key, matching the HTTP protocol used in the request.

Removed

• Remove rack.multithread/rack.multiprocess/rack.run_once. These variables generally come too late to be useful. (#1720, [@​ioquatix], [@​jeremyevans]))
• Remove deprecated Rack::Request::SCHEME_WHITELIST. ([@​jeremyevans])
• Remove internal cookie deletion using pattern matching, there are very few practical cases where it would be useful and browsers handle it correctly without us doing anything special. (#1844, [@​ioquatix])

Added

• Rack::Headers added to support lower-case header keys. ([@​jeremyevans])
• Rack::Utils#set_cookie_header now supports escape_key: false to avoid key escaping. ([@​jeremyevans])
• Rack::RewindableInput supports size. (@​ahorek)
• Rack::RewindableInput::Middleware added for making rack.input rewindable. ([@​jeremyevans])
• The RFC 7239 Forwarded header is now supported and considered by default when looking for information on forwarding, falling back to the X-Forwarded-* headers. Rack::Request.forwarded_priority accessor has been added for configuring the priority of which header to check. (#1423, [@​jeremyevans])
• Allow response headers to contain array of values. (#1598, [@​ioquatix])

Changed

• BREAKING CHANGE: Require status to be an Integer. (#1662, @​olleolleolle)
• BREAKING CHANGE: Query parsing now treats parameters without = as having the empty string value instead of nil value, to conform to the URL spec. (#1696, [@​jeremyevans])
• Relax validations around Rack::Request#host and Rack::Request#hostname. (#1606, @​pvande)
• Removed antiquated handlers: FCGI, LSWS, SCGI, Thin. (#1658, [@​ioquatix])
• Removed options from Rack::Builder.parse_file and Rack::Builder.load_file. (#1663, [@​ioquatix])
• Rack::HTTP_VERSION has been removed and the HTTP_VERSION env setting is no longer set in the CGI and Webrick handlers. (#970, [@​jeremyevans])
• Rack::Request#[] and #[]= now warn even in non-verbose mode. (#1277, [@​jeremyevans])
• Decrease default allowed parameter recursion level from 100 to 32. (#1640, [@​jeremyevans])
• Attempting to parse a multipart response with an empty body now raises Rack::Multipart::EmptyContentError. (#1603, [@​jeremyevans])
• Rack::Utils.secure_compare uses OpenSSL's faster implementation if available. (#1711, @​bdewater)
• Rack::Request#POST now caches an empty hash if input content type is not parseable. (#749, [@​jeremyevans])
