[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 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::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])
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)
