-xss()` method. The Vanilla forums wrapper is used
- * to provide sensible defaults and a clean interface for HtmLawed.
- *
- * Changes:
- *
- * * Add `DataTables/HtmLawed` namespace to this and htmLawed - this is to ensure
- * that if htmLawed is included by any other aspect of the site it will not
- * result in a conflict.
- * * Use the OOP version of htmLawed (required a single updated to call it) to
- * make the namespacing relatively easy.
- * * Change the name of the Vanilla class so it don't conflict with the
- * htmLawed OOP class
- * * Update all `htmLawed::` references to `\DataTables\HtmLawed\HtmLawed::` in
- * the htmLawed file (to allow callbacks to operate correctly)
- * * Updated Vanilla wrapper to operate on PHP 5.3
