+## 3.4.1 Named Appends
+
+### Small bugfix
+
+If your CSP did not define a script/style-src and you tried to use a script/style nonce, the nonce would be added to the page but it would not be added to the CSP. A workaround is to define a script/style src but now it should add the missing directive (and populate it with the default-src).
+
+### Named Appends
+
+Named Appends are blocks of code that can be reused and composed during requests. e.g. If a certain partial is rendered conditionally, and the csp needs to be adjusted for that partial, you can create a named append for that situation. The value returned by the block will be passed into `append_content_security_policy_directives`. The current request object is passed as an argument to the block for even more flexibility.
+
+```ruby
+def show
+  if include_widget?
+    @widget = widget.render
+    use_content_security_policy_named_append(:widget_partial)
+  end
+end
+
+
+SecureHeaders::Configuration.named_append(:widget_partial) do |request|
+  if request.controller_instance.current_user.in_test_bucket?
+    SecureHeaders.override_x_frame_options(request, "DENY")
+    { child_src: %w(beta.thirdpartyhost.com) }
+  else
+    { child_src: %w(thirdpartyhost.com) }
+  end
+end
+```
+
+You can use as many named appends as you would like per request, but be careful because order of inclusion matters. Consider the following:
+
+```ruby
+SecureHeader::Configuration.default do |config|
+  config.csp = { default_src: %w('self')}
+end
+
+SecureHeaders::Configuration.named_append(:A) do |request|
+  { default_src: %w(myhost.com) }
+end
+
+SecureHeaders::Configuration.named_append(:B) do |request|
+  { script_src: %w('unsafe-eval') }
+end
+```
+
+The following code will produce different policies due to the way policies are normalized (e.g. providing a previously undefined directive that inherits from `default-src`, removing host source values when `*` is provided. Removing `'none'` when additional values are present, etc.):
+
+```ruby
+def index
+  use_content_security_policy_named_append(:A)
+  use_content_security_policy_named_append(:B)
+  # produces default-src 'self' myhost.com; script-src 'self' myhost.com 'unsafe-eval';
+end
+
+def show
+  use_content_security_policy_named_append(:B)
+  use_content_security_policy_named_append(:A)
+  # produces default-src 'self' myhost.com; script-src 'self' 'unsafe-eval';
+end
+```
+
 ## 3.4.0 the frame-src/child-src transition for Firefox.
 
 Handle the `child-src`/`frame-src` transition semi-intelligently across versions. I think the code best descibes the behavior here:
