+## 5.1.0 (2019-09-07)
+
+### Features
+
+* Added a `:parser_options` config hash, which makes it possible to pass custom
+  parsing options to Nokogumbo. [@austin-wang - #194][194]
+
+### Bug Fixes
+
+* Non-characters and non-whitespace control characters are now stripped from
+  HTML input before parsing to comply with the HTML Standard's [preprocessing
+  guidelines][html-preprocessing]. Prior to this Sanitize had adhered to [older
+  W3C guidelines][unicode-xml] that have since been withdrawn. [#179][179]
