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.writeln "email_address,updated_at"
  
    @subscribers.find_each do |subscriber|
      stream.writeln [ subscriber.email_address, subscriber.updated_at ].join(",")
    end
  end

• Add ActionController::Live::Buffer#writeln to write a line to the stream with a newline included.

  DHH

• 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"
  

  Rafael Mendonça França

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

  Rafael Mendonça França

• Fix error in ActionController::LogSubscriber that would happen when throwing inside a controller action.

  Janko Marohnić

• Allow anything with #to_str (like Addressable::URI) as a redirect_to location

  ojab

• Change the request method to a GET when passing failed requests down to config.exceptions_app.

  Alex Robbin

• Deprecate the ability to assign a single value to config.action_dispatch.trusted_proxies as RemoteIp middleware behaves inconsistently depending on whether this is configured with a single value or an enumerable.

  Fixes #40772

  Christian Sutter

• 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.
