+ Transparently handles inline elements in block context (blockquote) ! Added GET method to demo for easier validation, added 50kb max input size ! New directive %HTML.BlockWrapper, for block-ifying inline elements ! New directive %HTML.Parent, allows you to only allow inline content - Added missing type to ChildDef_Chameleon . ChildDef_Required guards against empty tags . Lookup table HTMLDefinition->info_flow_elements added . Added peace-of-mind variable initialization to Strategy_FixNesting git-svn-id: http://htmlpurifier.org/svnroot/htmlpurifier/trunk@560 48356398-32a2-884e-a903-53898d9a118a
