  1. HTML Purifier 4.8.0 is a bugfix release, collecting a year
  2. of accumulated bug fixes. In particular, we fixed some minor
  3. bugs and now declare full PHP 7 compatibility. The primary
  4. backwards-incompatible change is that HTML Purifier will now
  5. add rel="noreferrer" to all links with target attributes
  6. (you can disable this with %HTML.TargetNoReferrer.) Other
  7. changes: new configuration options %CSS.AllowDuplicates and
  8. %Attr.ID.HTML5; border-radius is partially supported when
  9. %CSS.AllowProprietary, and tel URIs are supported by default.
