## 4.0.0

* Optimize `ERB::Util.html_escape` [#27](https://github.com/ruby/erb/pull/27)
  * No longer duplicate an argument string when nothing is escaped.
     * This makes `ERB::Util.html_escape` faster than `CGI.escapeHTML` in no-escape cases.
  * It skips calling `#to_s` when an argument is already a String.
* Define `ERB::Escape.html_escape` as an alias to `ERB::Util.html_escape` [#38](https://github.com/ruby/erb/pull/38)
  * `ERB::Util.html_escape` is known to be monkey-patched by Rails.
    `ERB::Escape.html_escape` is useful when you want a non-monkey-patched version.
* Drop deprecated `-S` option from `erb` command
