SPEC Changes

Added

• rackup supports multiple -r options and will require all arguments. (@​jeremyevans)
• Server supports an array of paths to require for the :require option. (@​khotta)
• Files supports multipart range requests. (@​fatkodima)
• Multipart::UploadedFile supports an IO-like object instead of using the filesystem, using :filename and :io options. (@​jeremyevans)
• Multipart::UploadedFile supports keyword arguments :path, :content_type, and :binary in addition to positional arguments. (@​jeremyevans)
• Static supports a :cascade option for calling the app if there is no matching file. (@​jeremyevans)
• Session::Abstract::SessionHash#dig. (@​jeremyevans)
• Response.[] and MockResponse.[] for creating instances using status, headers, and body. (@​ioquatix)
• Convenient cache and content type methods for Rack::Response. (#1555, @​ioquatix)

Changed

• Request#params no longer rescues EOFError. (@​jeremyevans)

• Request#host_with_port no longer includes a colon for a missing or empty port. (@​AlexWayfer)
• All handlers uses keywords arguments instead of an options hash argument. (@​ioquatix)
• Files handling of range requests no longer return a body that supports to_path, to ensure range requests are handled correctly. (@​jeremyevans)
• Multipart::Generator only includes Content-Length for files with paths, and Content-Disposition filename if the UploadedFile instance has one. (@​jeremyevans)
