+= New Features
+
+* A permissions_policy plugin has been added that allows you to easily set a
+  Permissions-Policy header for the application, which browsers can use to
+  determine whether to allow specific functionality on the returned page
+  (mainly related to which JavaScript APIs the page is allowed to use).
+
+  You would generally call the plugin with a block to set the default policy:
+
+    plugin :permissions_policy do |pp|
+      pp.camera :none
+      pp.fullscreen :self
+      pp.clipboard_read :self, 'https://example.com'
+    end
+
+  Then, anywhere in the routing tree, you can customize the policy for just that
+  branch or action using the same block syntax:
+
+    r.get 'foo' do
+      permissions_policy do |pp|
+        pp.camera :self
+      end
+      # ...
+    end
+
+  In addition to using a block, you can also call methods on the object returned
+  by the method:
+
+    r.get 'foo' do
+      permissions_policy.camera :self
+      # ...
+    end
+
+  You can use the :default plugin option to set the default for all settings.
+  For example, to disallow all access for each setting by default:
+
+    plugin :permissions_policy, default: :none
+
+  The following methods are available for configuring the permissions policy,
+  which specify the setting (substituting _ with -): 
+
+  * accelerometer
+  * ambient_light_sensor
+  * autoplay
+  * bluetooth
+  * camera
+  * clipboard_read
+  * clipboard_write
+  * display_capture
+  * encrypted_media
+  * fullscreen
+  * geolocation
+  * gyroscope
+  * hid
+  * idle_detection
+  * keyboard_map
+  * magnetometer
+  * microphone
+  * midi
+  * payment
+  * picture_in_picture
+  * publickey_credentials_get
+  * screen_wake_lock
+  * serial
+  * sync_xhr
+  * usb
+  * web_share
+  * window_management
+
+  All of these methods support any number of arguments, and each argument should
+  be one of the following values:
+
+  :all :: Grants permission to all domains (must be only argument)
+  :none :: Does not allow permission at all (must be only argument)
+  :self :: Allows feature in current document and any nested browsing contexts
+           that use the same domain as the current document.
+  :src :: Allows feature in current document and any nested browsing contexts
+          that use the same domain as the src of the iframe.
+  String :: Specifies origin domain where access is allowed
+
+  When calling a method with no arguments, the setting is removed from the policy instead
+  of being left empty, since all of these setting require at least one value.  Likewise,
+  if the policy does not have any settings, the header will not be added.
+
+  Calling the method overrides any previous setting.  Each of the methods has +add_*+ and
+  +get_*+ methods defined. The +add_*+ method appends to any existing setting, and the +get_*+ method
+  returns the current value for the setting (this will be +:all+ if all domains are allowed, or
+  any array of strings/:self/:src).
+
+    permissions_policy.fullscreen :self, 'https://example.com'
+    # fullscreen (self "https://example.com")
+
+    permissions_policy.add_fullscreen 'https://*.example.com'
+    # fullscreen (self "https://example.com" "https://*.example.com")
+
+    permissions_policy.get_fullscreen
+    # => [:self, "https://example.com", "https://*.example.com"]
+
+  The clear method can be used to remove all settings from the policy.
