  • Multiple filters can be used for each filter tag. Filter names should be specified as an ordered comma separated list.
  • Added filter rel_nofollow. This tags all external links with the rel=”nofollow” attribute.
  • Added filter external_links. This tags all external links by appending ”[domainname.com]” after the link. It will also set the link’s title to “domainname.com” if a title is not found.
