rails--rails/actionpack/CHANGELOG.md

• Add cache_control: {} option to fresh_when and stale?

  Works as a shortcut to set response.cache_control with the above methods.

  Jacopo Beschi

• Writing into a disabled session will now raise an error.

  Previously when no session store was set, writing into the session would silently fail.

  Jean Boussier

• Add support for 'require-trusted-types-for' and 'trusted-types' headers.

  Fixes #42034

  lfalcao

• Remove inline styles and address basic accessibility issues on rescue templates.

  Jacob Herrington

• Add support for 'private, no-store' Cache-Control headers.

  Previously, 'no-store' was exclusive; no other directives could be specified.

  Alex Smith

• Expand payload of unpermitted_parameters.action_controller instrumentation to allow subscribers to know which controller action received unpermitted parameters.

  bbuchalter

• 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
  

  DHH

• 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.
