     `assert_select_encoded`
     `assert_select_email`
 
+    Note:
+    The substitution values syntax in `assert_select` has changed.
+
+    `assert_select "div#?", /\d+/`
+    `assert_select "div:match('id', ?)", /\d+/`
+
+    The attribute to match should be enclosed in quotes to avoid
+    issues with Nokogiri's css selector syntax parsing.
+    It is not necessary to do so with the question mark.

+
+*   Loofah replaces html-scanner in `sanitize_helper`
+
+    `sanitize` can now take a `Loofah::Scrubber` for powerful scrubbing.
+    [See some examples of scrubbers here](https://github.com/flavorjones/loofah#loofahscrubber)
+
+    `PermitScrubber` has been added. Set the attributes and tags you want to keep and get everything else stripped.
+
+    `TargetScrubber` has been added. Set the attributes and tags you want to have stripped and keep everything else.
+
+    The documentation for `PermitScrubber` and `TargetScrubber` explains how you can gain complete control over when and how elements should be stripped.
