@ -10,12 +10,28 @@ NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
==========================
3.1.0, unknown release date
# Unnecessary references to objects (vestiges of PHP4) removed from method
signatures. The following methods do not need references when assigning from
them and will result in E_STRICT errors if you try:
+ HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
+ HTMLPurifier_ConfigSchema::instance()
+ HTMLPurifier_DefinitionCacheFactory::instance()
+ HTMLPurifier_DefinitionCacheFactory->create()
+ HTMLPurifier_DoctypeRegistry->register()
+ HTMLPurifier_DoctypeRegistry->get()
+ HTMLPurifier_HTMLModule->addElement()
+ HTMLPurifier_HTMLModule->addBlankElement()
+ HTMLPurifier_LanguageFactory::instance()
- InterchangeBuilder now alphabetizes its lists
- Validation error in configdoc output fixed
- Iconv errors muted even with custom error handlers
- Iconv and other encoding errors muted even with custom error handlers that
do not honor error_reporting
- Add protection against imagecrash attack with CSS height/width
- HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
. Out-of-date documentation revised
. UTF-8 encoding check optimization as suggested by Diego
. HTMLPurifier_Error removed in favor of exceptions
. More copy() function removed; should use clone instead
3.1.0rc1, released 2008-04-22
# Autoload support added. Internal require_once's removed in favor of an
