# Rails::Deprecated::Sanitizer
In Rails 4.2 HTML sanitization has been rewritten using a more secure library.
This gem includes the old behavior shipping with Rails 4.2 and before. It is
strictly provided to ease migration.
To downgrade add `gem 'rails-deprecated_sanitizer'` to your Gemfile.
See the Rails 4.2 upgrade guide for more information.
You can read more about the new sanitization implementation here: [rails-html-sanitizer](https://github.com/rails/rails-html-sanitizer).
