HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and
up. It has no core dependencies with other libraries. PHP
4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0.
HTML Purifier is not compatible with zend.ze1_compatibility_mode.
These optional extensions can enhance the capabilities of HTML Purifier:

. Internal change
==========================
4.3.0, released 2011-03-27
# Fixed broken caching of customized raw definitions, but requires an
API change. The old API still works but will emit a warning,
see http://htmlpurifier.org/docs/enduser-customize.html#optimized
for how to upgrade your code.
# Protect against Internet Explorer innerHTML behavior by specially
treating attributes with backticks but no angled brackets, quotes or
spaces. This constitutes a slight semantic change, which can be
reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
and Mario Heiderich.
# Protect against cssText/innerHTML by restricting allowed characters
used in fonts further than mandated by the specification and encoding
some extra special characters in URLs. Reported by Neike
Taika-Tessaro and Mario Heiderich.
! Added %HTML.Nofollow to add rel="nofollow" to external links.
! More types of SPL autoloaders allowed on later versions of PHP.
! Implementations for position, top, left, right, bottom, z-index
when %CSS.Trusted is on.
! Add %Cache.SerializerPermissions option for custom serializer
directory/file permissions
! Fix longstanding bug in Flash support for non-IE browsers, and
allow more wmode attributes.
! Add %CSS.AllowedFonts to restrict permissible font names.
- Switch to an iterative traversal of the DOM, which prevents us
from running out of stack space for deeply nested documents.
Thanks Maxim Krizhanovsky for contributing a patch.
- Make removal of conditional IE comments ungreedy; thanks Bernd
for reporting.
- Escape CDATA before removing Internet Explorer comments.
- Fix removal of id attributes under certain conditions by ensuring
armor attributes are preserved when recreating tags.
- Check if schema.ser was corrupted.
- Check if zend.ze1_compatibility_mode is on, and error out if it is.
This safety check is only done for HTMLPurifier.auto.php; if you
are using standalone or the specialized includes files, you're
expected to know what you're doing.
- Stop repeatedly writing the cache file after I'm done customizing a
raw definition. Reported by ajh.
- Switch to using require_once in the Bootstrap to work around bad
interaction with Zend Debugger and APC. Reported by Antonio Parraga.
- Fix URI handling when hostname is missing but scheme is present.
Reported by Neike Taika-Tessaro.
- Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
for reporting.
- Fix harmless notice from indexing into empty string. Thanks Matthijs
Kooijman <matthijs@stdin.nl> for reporting.
- Don't autoclose no parent elements are able to support the element
that triggered the autoclose. In particular fixes strange behavior
of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
4.2.0, released 2010-09-15
! Added %Core.RemoveProcessingInstructions, which lets you remove
<? ... ?> statements.
! Added %URI.DisableResources functionality; the directive originally
did nothing. Thanks David Rothstein for reporting.
! Add documentation about configuration directive types.
! Add %CSS.ForbiddenProperties configuration directive.
! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
to utilize full-screen mode.
! Add optional support for the <code>file</code> URI scheme, enable
by explicitly setting %URI.AllowedSchemes.
! Add %Core.NormalizeNewlines options to allow turning off newline
normalization.
- Fix improper handling of Internet Explorer conditional comments
by parser. Thanks zmonteca for reporting.
- Fix missing attributes bug when running on Mac Snow Leopard and APC.
Thanks sidepodcast for the fix.
- Warn if an element is allowed, but an attribute it requires is
not allowed.
4.1.1, released 2010-05-31
- Fix undefined index warnings in maintenance scripts.
- Fix bug in DirectLex for parsing elements with a single attribute

// - Spaces require quoting, though most parsers will do
// the right thing if there aren't any characters that
// can be misinterpreted
// - Dashes rarely occur, but they fairly unproblematic
// for parsing/rendering purposes.
// The above characters cover the majority of Western font
// names.
// - Arbitrary Unicode characters not in ASCII. Because
// most parsers give little thought to Unicode, treatment
// of these codepoints is basically uniform, even for
// punctuation-like codepoints. These characters can
// show up in non-Western pages and are supported by most
// major browsers, for example: "ＭＳ 明朝" is a
// legitimate font-name
// <http://ja.wikipedia.org/wiki/MS_明朝>. See
// the CSS3 spec for more examples:
// <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>
// You can see live samples of these on the Internet:
// <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>
// However, most of these fonts have ASCII equivalents:
// for example, 'MS Mincho', and it's considered
// professional to use ASCII font names instead of
// Unicode font names. Thanks Takeshi Terada for
// providing this information.
// The following characters, to my knowledge, have not been
// used to name font names.
// - Single quote. While theoretically you might find a
// font name that has a single quote in its name (serving
// as an apostrophe, e.g. Dave's Scribble), I haven't
// been able to find any actual examples of this.
// Internet Explorer's cssText translation (which I
// believe is invoked by innerHTML) normalizes any
// quoting to single quotes, and fails to escape single
// quotes. (Note that this is not IE's behavior for all
// CSS properties, just some sort of special casing for
// font-family). So a single quote *cannot* be used
// safely in the font-family context if there will be an
// innerHTML/cssText translation. Note that Firefox 3.x
// does this too.
// - Double quote. In IE, these get normalized to
// single-quotes, no matter what the encoding. (Fun
// fact, in IE8, the 'content' CSS property gained
// support, where they special cased to preserve encoded
// double quotes, but still translate unadorned double
// quotes into single quotes.) So, because their
// fixpoint behavior is identical to single quotes, they
// cannot be allowed either. Firefox 3.x displays
// single-quote style behavior.
// - Backslashes are reduced by one (so \\ -> \) every
// iteration, so they cannot be used safely. This shows
// up in IE7, IE8 and FF3
// - Semicolons, commas and backticks are handled properly.
// - The rest of the ASCII punctuation is handled properly.
// We haven't checked what browsers do to unadorned
// versions, but this is not important as long as the
// browser doesn't /remove/ surrounding quotes (as IE does
// for HTML).
//
// With these results in hand, we conclude that there are
// various levels of safety:
// - Paranoid: alphanumeric, spaces and dashes(?)
// - International: Paranoid + non-ASCII Unicode
// - Edgy: Everything except quotes, backslashes
// - NoJS: Standards compliance, e.g. sod IE. Note that
// with some judicious character escaping (since certain
// types of escaping doesn't work) this is theoretically
// OK as long as innerHTML/cssText is not called.
// We believe that international is a reasonable default
// (that we will implement now), and once we do more
// extensive research, we may feel comfortable with dropping
// it down to edgy.
