@ -15,6 +15,9 @@ NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
! Experimental AutoFormat functionality added: auto-paragraph and
linkify your HTML input by setting %AutoFormat.AutoParagraph and
%AutoFormat.Linkify to true
! Newlines normalized internally, and then converted back to the
value of PHP_EOL. If this is not desired, set your newline format
using %Output.Newline.
- Clean up special case code for <script> tags
- Reorder includes for DefinitionCache decorators, fixes a possible
missing class error
