• Allow system test screen shots to be taken more than once in a test by prefixing the file name with an incrementing counter.

  Add an environment variable RAILS_SYSTEM_TESTING_SCREENSHOT_HTML to enable saving of HTML during a screenshot in addition to the image. This uses the same image name, with the extension replaced with .html

• Add Vary: Accept header when using Accept header for response

  For some requests like /users/1, Rails uses requests' Accept header to determine what to return. And if we don't add Vary in the response header, browsers might accidentally cache different types of content, which would cause issues: e.g. javascript got displayed instead of html content. This PR fixes these issues by adding Vary: Accept in these types of requests. For more detailed problem description, please read:

• Add DSL for configuring HTTP Feature Policy

  This new DSL provides a way to configure a HTTP Feature Policy at a global or per-controller level. Full details of HTTP Feature Policy specification and guidelines can be found at MDN:

  https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Feature-Policy

  Example global policy

  Rails.application.config.feature_policy do |f|
    f.camera      :none
    f.gyroscope   :none
    f.microphone  :none
    f.usb         :none
    f.fullscreen  :self
    f.payment     :self, "https://secure.example.com"
  end
  

  Example controller level policy

  class PagesController < ApplicationController
    feature_policy do |p|
      p.geolocation "https://example.com"
    end
  end

  Fixes #35137.

• Keep part when scope option has value.

  When a route was defined within an optional scope, if that route didn't take parameters the scope was lost when using path helpers. This commit ensures scope is kept both when the route takes parameters or when it doesn't.

  Fixes #33219.

  Alberto Almagro

• Added deep_transform_keys and deep_transform_keys! methods to ActionController::Parameters.

  Gustavo Gutierrez

• Calling ActionController::Parameters#transform_keys/! without a block now returns an enumerator for the parameters instead of the underlying hash.

  Eugene Kenny

• Fix strong parameters blocks all attributes even when only some keys are invalid (non-numerical). It should only block invalid key's values instead.
