+### 0.5
+
+Released on Jun 24 2019.
+
+**Changes:**
+
+* Imported a fork of the Gumbo C library and applied many
+  [bug fixes and improvements][lib readme]. The parser code is now
+  built along with the Lua bindings and an external installation of
+  libgumbo is no longer required.
+* Changed the `gumbo.parse()` function to take a [table of options]
+  as the second parameter. The old API still continues to work, but
+  any new options will only be supported by the new API.
+* Various bug fixes to DOM methods.
+* Many performance improvements.
