rails--rails/actionpack/CHANGELOG.md

• Add ActionController::Live#send_stream that makes it more convenient to send generated streams:

  send_stream(filename: "subscribers.csv") do |stream|
    stream.write "email_address,updated_at\n"
  
    @subscribers.find_each do |subscriber|
      stream.write "#{subscriber.email_address},#{subscriber.updated_at}\n"
    end
  end

• ActionDispatch::Request#content_type now returned Content-Type header as it is.

  Previously, ActionDispatch::Request#content_type returned value does NOT contain charset part. This behavior changed to returned Content-Type header containing charset part as it is.

  If you want just MIME type, please use ActionDispatch::Request#media_type instead.

  Before:

  request = ActionDispatch::Request.new("CONTENT_TYPE" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv"
  

  After:

  request = ActionDispatch::Request.new("Content-Type" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv; header=present; charset=utf-16"
  request.media_type   #=> "text/csv"

• Change ActionDispatch::Request#media_type to return nil when the request don't have a Content-Type header.

• Add redirect_back_or_to(fallback_location, **) as a more aesthetically pleasing version of redirect_back fallback_location:, **. The old method name is retained without explicit deprecation.
