+* Introduce `render :html` as an option to render HTML content with a content
+ type of `text/html`. This rendering option calls `ERB::Util.html_escape`
+ internally to escape unsafe HTML string, so you will have to mark your
+ string as html safe if you have any HTML tag in it.
+
+ Please see #12374 for more detail.
+
+ *Prem Sichanugrist*
+
* Introduce `render :plain` as an option to render content with a content type
of `text/plain`. This is the preferred option if you are planning to render
a plain text content.
