-
- If HTML Purifier's tag set is unsatisfactory for your needs, you
- can overload it with your own list of tags to allow. Note that this
- method is subtractive: it does its job by taking away from HTML Purifier
- usual feature set, so you cannot add a tag that HTML Purifier never
- supported in the first place (like embed, form or head). If you
- change this, you probably also want to change %HTML.AllowedAttributes.
-
-
- Warning: If another directive conflicts with the
- elements here, that directive will win and override.

+Install
+ How to install HTML Purifier
+
+HTML Purifier is designed to run out of the box, so actually using the
+library is extremely easy. (Although... if you were looking for a
+step-by-step installation GUI, you've downloaded the wrong software!)
+
+While the impatient can get going immediately with some of the sample
+code at the bottom of this library, it's well worth reading this entire
+document--most of the other documentation assumes that you are familiar
+with these contents.
+
+
+---------------------------------------------------------------------------
+1. Compatibility
+
+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:
+
+ * iconv : Converts text to and from non-UTF-8 encodings
+ * bcmath : Used for unit conversion and imagecrash protection
+ * tidy : Used for pretty-printing HTML
+
+These optional libraries can enhance the capabilities of HTML Purifier:
+
+ * CSSTidy : Clean CSS stylesheets using %Core.ExtractStyleBlocks
+ * Net_IDNA2 (PEAR) : IRI support using %Core.EnableIDNA
+
+---------------------------------------------------------------------------
+2. Reconnaissance
+
+A big plus of HTML Purifier is its inerrant support of standards, so
+your web-pages should be standards-compliant. (They should also use
+semantic markup, but that's another issue altogether, one HTML Purifier
+cannot fix without reading your mind.)
+
+HTML Purifier can process these doctypes:
+
+* XHTML 1.0 Transitional (default)
+* XHTML 1.0 Strict
+* HTML 4.01 Transitional
+* HTML 4.01 Strict
+* XHTML 1.1
+
+...and these character encodings:
+
+* UTF-8 (default)
+* Any encoding iconv supports (with crippled internationalization support)
+
+These defaults reflect what my choices would be if I were authoring an
+HTML document, however, what you choose depends on the nature of your
+codebase. If you don't know what doctype you are using, you can determine
+the doctype from this identifier at the top of your source code:
+
+
+
+...and the character encoding from this code:
+
+
+
+If the character encoding declaration is missing, STOP NOW, and
+read 'docs/enduser-utf8.html' (web accessible at
+http://htmlpurifier.org/docs/enduser-utf8.html). In fact, even if it is
+present, read this document anyway, as many websites specify their
+document's character encoding incorrectly.
+
+
+---------------------------------------------------------------------------
+3. Including the library
+
+The procedure is quite simple:
+
+ require_once '/path/to/library/HTMLPurifier.auto.php';
+
+This will setup an autoloader, so the library's files are only included
+when you use them.
+
+Only the contents in the library/ folder are necessary, so you can remove
+everything else when using HTML Purifier in a production environment.
+
+If you installed HTML Purifier via PEAR, all you need to do is:
+
+ require_once 'HTMLPurifier.auto.php';
+
+Please note that the usual PEAR practice of including just the classes you
+want will not work with HTML Purifier's autoloading scheme.
+
+Advanced users, read on; other users can skip to section 4.
+
+Autoload compatibility
+----------------------
+
+ HTML Purifier attempts to be as smart as possible when registering an
+ autoloader, but there are some cases where you will need to change
+ your own code to accomodate HTML Purifier. These are those cases:
+
+ PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
+ Because spl_autoload_register() doesn't exist in early versions
+ of PHP 5, HTML Purifier has no way of adding itself to the autoload
+ stack. Modify your __autoload function to test
+ HTMLPurifier_Bootstrap::autoload($class)
+
+ For example, suppose your autoload function looks like this:
+
+ function __autoload($class) {
+ require str_replace('_', '/', $class) . '.php';
+ return true;
+ }
+
+ A modified version with HTML Purifier would look like this:
+
+ function __autoload($class) {
+ if (HTMLPurifier_Bootstrap::autoload($class)) return true;
+ require str_replace('_', '/', $class) . '.php';
+ return true;
+ }
+
+ Note that there *is* some custom behavior in our autoloader; the
+ original autoloader in our example would work for 99% of the time,
+ but would fail when including language files.
+
+ AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
+ spl_autoload_register() has the curious behavior of disabling
+ the existing __autoload() handler. Users need to explicitly
+ spl_autoload_register('__autoload'). Because we use SPL when it
+ is available, __autoload() will ALWAYS be disabled. If __autoload()
+ is declared before HTML Purifier is loaded, this is not a problem:
+ HTML Purifier will register the function for you. But if it is
+ declared afterwards, it will mysteriously not work. This
+ snippet of code (after your autoloader is defined) will fix it:
+
+ spl_autoload_register('__autoload')
+
+ Users should also be on guard if they use a version of PHP previous
+ to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
+ for you, which can collide with an autoloader that was added by *you*
+ later.
+
+
+For better performance
+----------------------
+
+ Opcode caches, which greatly speed up PHP initialization for scripts
+ with large amounts of code (HTML Purifier included), don't like
+ autoloaders. We offer an include file that includes all of HTML Purifier's
+ files in one go in an opcode cache friendly manner:
+
+ // If /path/to/library isn't already in your include path, uncomment
+ // the below line:
+ // require '/path/to/library/HTMLPurifier.path.php';
+
+ require 'HTMLPurifier.includes.php';
+
+ Optional components still need to be included--you'll know if you try to
+ use a feature and you get a class doesn't exists error! The autoloader
+ can be used in conjunction with this approach to catch classes that are
+ missing. Simply add this afterwards:
+
+ require 'HTMLPurifier.autoload.php';
+
+Standalone version
+------------------
+
+ HTML Purifier has a standalone distribution; you can also generate
+ a standalone file from the full version by running the script
+ maintenance/generate-standalone.php . The standalone version has the
+ benefit of having most of its code in one file, so parsing is much
+ faster and the library is easier to manage.
+
+ If HTMLPurifier.standalone.php exists in the library directory, you
+ can use it like this:
+
+ require '/path/to/HTMLPurifier.standalone.php';
+
+ This is equivalent to including HTMLPurifier.includes.php, except that
+ the contents of standalone/ will be added to your path. To override this
+ behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
+ be found (usually, this will be one directory up, the "true" library
+ directory in full distributions). Don't forget to set your path too!
+
+ The autoloader can be added to the end to ensure the classes are
+ loaded when necessary; otherwise you can manually include them.
+ To use the autoloader, use this:
+
+ require 'HTMLPurifier.autoload.php';
+
+For advanced users
+------------------
+
+ HTMLPurifier.auto.php performs a number of operations that can be done
+ individually. These are:
+
+ HTMLPurifier.path.php
+ Puts /path/to/library in the include path. For high performance,
+ this should be done in php.ini.
+
+ HTMLPurifier.autoload.php
+ Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
+
+ You can do these operations by yourself--in fact, you must modify your own
+ autoload handler if you are using a version of PHP earlier than PHP 5.1.2
+ (See "Autoload compatibility" above).
+
+
+---------------------------------------------------------------------------
+4. Configuration
+
+HTML Purifier is designed to run out-of-the-box, but occasionally HTML
+Purifier needs to be told what to do. If you answer no to any of these
+questions, read on; otherwise, you can skip to the next section (or, if you're
+into configuring things just for the heck of it, skip to 4.3).
+
+* Am I using UTF-8?
+* Am I using XHTML 1.0 Transitional?
+
+If you answered no to any of these questions, instantiate a configuration
+object and read on:
+
+ $config = HTMLPurifier_Config::createDefault();
+
+
+4.1. Setting a different character encoding
+
+You really shouldn't use any other encoding except UTF-8, especially if you
+plan to support multilingual websites (read section three for more details).
+However, switching to UTF-8 is not always immediately feasible, so we can
+adapt.
+
+HTML Purifier uses iconv to support other character encodings, as such,
+any encoding that iconv supports
+HTML Purifier supports with this code:
+
+ $config->set('Core.Encoding', /* put your encoding here */);
+
+An example usage for Latin-1 websites (the most common encoding for English
+websites):
+
+ $config->set('Core.Encoding', 'ISO-8859-1');
+
+Note that HTML Purifier's support for non-Unicode encodings is crippled by the
+fact that any character not supported by that encoding will be silently
+dropped, EVEN if it is ampersand escaped. If you want to work around
+this, you are welcome to read docs/enduser-utf8.html for a fix,
+but please be cognizant of the issues the "solution" creates (for this
+reason, I do not include the solution in this document).
+
+
+4.2. Setting a different doctype
+
+For those of you using HTML 4.01 Transitional, you can disable
+XHTML output like this:
+
+ $config->set('HTML.Doctype', 'HTML 4.01 Transitional');
+
+Other supported doctypes include:
+
+ * HTML 4.01 Strict
+ * HTML 4.01 Transitional
+ * XHTML 1.0 Strict
+ * XHTML 1.0 Transitional
+ * XHTML 1.1
+
+
+4.3. Other settings
+
+There are more configuration directives which can be read about
+here: They're a bit boring,
+but they can help out for those of you who like to exert maximum control over
+your code. Some of the more interesting ones are configurable at the
+demo and are well worth looking into
+for your own system.
+
+For example, you can fine tune allowed elements and attributes, convert
+relative URLs to absolute ones, and even autoparagraph input text! These
+are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
+%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
+translates to:
+
+ $config->set('Namespace.Directive', $value);
+
+E.g.
+
+ $config->set('HTML.Allowed', 'p,b,a[href],i');
+ $config->set('URI.Base', 'http://www.example.com');
+ $config->set('URI.MakeAbsolute', true);
+ $config->set('AutoFormat.AutoParagraph', true);
+
+
+---------------------------------------------------------------------------
+5. Caching
+
+HTML Purifier generates some cache files (generally one or two) to speed up
+its execution. For maximum performance, make sure that
+library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
+
+If you are in the library/ folder of HTML Purifier, you can set the
+appropriate permissions using:
+
+ chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
+
+If the above command doesn't work, you may need to assign write permissions
+to all. This may be necessary if your webserver runs as nobody, but is
+not recommended since it means any other user can write files in the
+directory. Use:
+
+ chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
+
+You can also chmod files via your FTP client; this option
+is usually accessible by right clicking the corresponding directory and
+then selecting "chmod" or "file permissions".
+
+Starting with 2.0.1, HTML Purifier will generate friendly error messages
+that will tell you exactly what you have to chmod the directory to, if in doubt,
+follow its advice.
+
+If you are unable or unwilling to give write permissions to the cache
+directory, you can either disable the cache (and suffer a performance
+hit):
+
+ $config->set('Core.DefinitionCache', null);
+
+Or move the cache directory somewhere else (no trailing slash):
+
+ $config->set('Cache.SerializerPath', '/home/user/absolute/path');
+
+
+---------------------------------------------------------------------------
+6. Using the code
+
+The interface is mind-numbingly simple:
+
+ $purifier = new HTMLPurifier($config);
+ $clean_html = $purifier->purify( $dirty_html );
+
+That's it! For more examples, check out docs/examples/ (they aren't very
+different though). Also, docs/enduser-slow.html gives advice on what to
+do if HTML Purifier is slowing down your application.
+
+
+---------------------------------------------------------------------------
+7. Quick install
+
+First, make sure library/HTMLPurifier/DefinitionCache/Serializer is
+writable by the webserver (see Section 5: Caching above for details).
+If your website is in UTF-8 and XHTML Transitional, use this code:
+
+purify($dirty_html);
+?>
+
+If your website is in a different encoding or doctype, use this code:
+
+set('Core.Encoding', 'ISO-8859-1'); // replace with your encoding
+ $config->set('HTML.Doctype', 'HTML 4.01 Transitional'); // replace with your doctype
+ $purifier = new HTMLPurifier($config);
+
+ $clean_html = $purifier->purify($dirty_html);
+?>

+Installation
+ Comment installer HTML Purifier
+
+Attention : Ce document est encodé en UTF-8, si les lettres avec des accents
+ne s'affichent pas, prenez un meilleur éditeur de texte.
+
+L'installation de HTML Purifier est très simple, parce qu'il n'a pas besoin
+de configuration. Pour les utilisateurs impatients, le code se trouve dans le
+pied de page, mais je recommande de lire le document.
+
+1. Compatibilité
+
+HTML Purifier fonctionne avec PHP 5. PHP 5.0.5 est la dernière version testée.
+Il ne dépend pas d'autres librairies.
+
+Les extensions optionnelles sont iconv (généralement déjà installée) et tidy
+(répendue aussi). Si vous utilisez UTF-8 et que vous ne voulez pas l'indentation,
+vous pouvez utiliser HTML Purifier sans ces extensions.
+
+
+2. Inclure la librairie
+
+Quand vous devez l'utilisez, incluez le :
+
+ require_once('/path/to/library/HTMLPurifier.auto.php');
+
+Ne pas l'inclure si ce n'est pas nécessaire, car HTML Purifier est lourd.
+
+HTML Purifier utilise "autoload". Si vous avez défini la fonction __autoload,
+vous devez ajouter cette fonction :
+
+ spl_autoload_register('__autoload')
+
+Plus d'informations dans le document "INSTALL".
+
+3. Installation rapide
+
+Si votre site Web est en UTF-8 et XHTML Transitional, utilisez :
+
+purify($html_a_purifier);
+?>
+
+Sinon, utilisez :
+

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the

+ # Breaks back-compat
+ ! Feature
+ - Bugfix
+ + Sub-comment
+ . Internal change
+==========================
+
+4.7.0, released 2015-08-04
+# opacity is now considered a "tricky" CSS property rather than a
+ proprietary one.
+! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
+ an element should be considered "empty" (maybe preserve if it
+ has attributes), and modify iframe support so that the iframe
+ is removed if it is missing a src attribute. Thanks meeva for
+ reporting.
+- Don't truncate upon encountering
when using DOMLex. Thanks
+ Myrto Christina for finally convincing me to fix this.
+- Update YouTube filter for new code.
+- Fix parsing of rgb() values with spaces in them for 'border'
+ attribute.
+- Don't remove foo="" attributes if foo is a boolean attribute. Thanks
+ valME for reporting.
+
+4.6.0, released 2013-11-30
+# Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
+ Please update any verification scripts you may have.
+# URI parsing algorithm was made more strict, so only prefixes which
+ looks like schemes will actually be schemes. Thanks
+ Michael Gusev for fixing.
+# %Core.EscapeInvalidChildren is no longer supported, and no longer does
+ anything.
+! New directive %Core.AllowHostnameUnderscore which allows underscores
+ in hostnames.
+- Eliminate quadratic behavior in DOMLex by using a proper queue.
+ Thanks Ole Laursen for noticing this.
+- Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
+ behavior in the rest of the purificaiton pipeline. Thanks Chedburn
+ Networks for sponsoring this work.
+- Made Linkify URL parser a bit less permissive, so that non-breaking
+ spaces and commas are not included as part of URL. Thanks nAS for fixing.
+- Fix some bad interactions with %HTML.Allowed and injectors. Thanks
+ David Hirtz for reporting.
+- Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
+ for reporting.
+
+4.5.0, released 2013-02-17
+# Fix bug where stacked attribute transforms clobber each other;
+ this also means it's no longer possible to override attribute
+ transforms in later modules. No internal code was using this
+ but this may break some clients.
+# We now use SHA-1 to identify cached definitions, instead of MD5.
+! Support display:inline-block
+! Support for more white-space CSS values.
+! Permit underscores in font families
+! Support for page-break-* CSS3 properties when proprietary properties
+ are enabled.
+! New directive %Core.DisableExcludes; can be set to 'true' to turn off
+ SGML excludes checking. If HTML Purifier is removing too much text
+ and you don't care about full standards compliance, try setting this to
+ 'true'.
+- Use prepend for SPL autoloading on PHP 5.3 and later.
+- Fix bug with nofollow transform when pre-existing rel exists.
+- Fix bug where background:url() always gets lower-cased
+ (but not background-image:url())
+- Fix bug with non lower-case color names in HTML
+- Fix bug where data URI validation doesn't remove temporary files.
+ Thanks Javier Marín Ros for reporting.
+- Don't remove certain empty tags on RemoveEmpty.
+
+4.4.0, released 2012-01-18
+# Removed PEARSax3 handler.
+# URI.Munge now munges URIs inside the same host that go from https
+ to http. Reported by Neike Taika-Tessaro.
+# Core.EscapeNonASCIICharacters now always transforms entities to
+ entities, even if target encoding is UTF-8.
+# Tighten up selector validation in ExtractStyleBlocks.
+ Non-syntactically valid selectors are now rejected, along with
+ some of the more obscure ones such as attribute selectors, the
+ :lang pseudoselector, and anything not in CSS2.1. Furthermore,
+ ID and class selectors now work properly with the relevant
+ configuration attributes. Also, mute errors when parsing CSS
+ with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
+! Added support for 'scope' attribute on tables.
+! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
+! Properly handle sub-lists directly nested inside of lists in
+ a standards compliant way, by moving them into the preceding
+! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
+ limited allowed comments in untrusted situations.
+! Implement iframes, and allow them to be used in untrusted mode with
+ %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
+ for submitting an initial version of the patch.
+! The Forms module now works properly for transitional doctypes.
+! Added support for internationalized domain names. You need the PEAR
+ Net_IDNA2 module to be in your path; if it is installed, ensure the
+ class can be loaded and then set %Core.EnableIDNA to true.
+- Color keywords are now case insensitive. Thanks Yzmir Ramirez
+ for reporting.
+- Explicitly initialize anonModule variable to null.
+- Do not duplicate nofollow if already present. Thanks 178
+ for reporting.
+- Do not add nofollow if hostname matches our current host. Thanks 178
+ for reporting, and Neike Taika-Tessaro for helping diagnose.
+- Do not unset parser variable; this fixes intermittent serialization
+ problems. Thanks Neike Taika-Tessaro for reporting, bill
+ <10010tiger@gmail.com> for diagnosing.
+- Fix iconv truncation bug, where non-UTF-8 target encodings see
+ output truncated after around 8000 characters. Thanks Jörg Ludwig
+ for reporting.
+- Fix broken table content model for XHTML1.1 (and also earlier
+ versions, although the W3C validator doesn't catch those violations).
+ Thanks GlitchMr for reporting.
+
+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.

+ 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 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
tags. Thanks pkuliga@gmail.com for reporting and
+ Neike Taika-Tessaro for debugging assistance.
+
+4.2.0, released 2010-09-15

+ 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

+- Fix undefined index warnings in maintenance scripts.
+- Fix bug in DirectLex for parsing elements with a single attribute
+ with entities.

+
+4.0.0, released 2009-07-07
+# APIs for ConfigSchema subsystem have substantially changed. See
+ docs/dev-config-bcbreaks.txt for details; in essence, anything that
+ had both namespace and directive now have a single unified key.
+# Some configuration directives were renamed, specifically:
+ %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
+ %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
+ %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
+ %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
+ As usual, the old directive names will still work, but will throw E_NOTICE
+ errors.
+# The allowed values for class have been relaxed to allow all of CDATA for
+ doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
+ %Attr.ClassUseCDATA to false.
+# Instead of appending the content model to an old content model, a blank
+ element will replace the old content model. You can use #SUPER to get
+ the old content model.
+! More robust support for name="" and id=""
+! HTMLPurifier_Config::inherit($config) allows you to inherit one
+ configuration, and have changes to that configuration be propagated
+ to all of its children.
+! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
+ the name attribute when set. Use with care. Thanks Ian Cook for
+ sponsoring.
+! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
+ tags that contain non-breaking spaces as well other whitespace. You
+ can also modify which tags should have maintained with
+ %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
+! Implement %Attr.AllowedClasses, which allows administrators to restrict
+ classes users can use to a specified finite set of classes, and
+ %Attr.ForbiddenClasses, which is the logical inverse.
+! You can now maintain your own configuration schema directories by
+ creating a config-schema.php file or passing an extra argument. Check
+ docs/dev-config-schema.html for more details.
+! Added HTMLPurifier_Config->serialize() method, which lets you save away
+ your configuration in a compact serial file, which you can unserialize
+ and use directly without having to go through the overhead of setup.
+- Fix bug where URIDefinition would not get cleared if it's directives got
+ changed.
+- Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
+- Fix bug in Linkify autoformatter involving http://foo
+- Make %URI.Munge not apply to links that have the same host as your host.
+- Prevent stray tag from truncating output, if a second
+ is present.
+. Created script maintenance/rename-config.php for renaming a configuration
+ directive while maintaining its alias. This script does not change source code.
+. Implement namespace locking for definition construction, to prevent
+ bugs where a directive is used for definition construction but is not
+ used to construct the cache hash.
+
+3.3.0, released 2009-02-16
+! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
+! Implement generic property list classess
+- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
+ does not do the "right thing" with characters not supported in the output
+ set.
+- Spellcheck UTF-8: The Secret To Character Encoding
+- Fix improper removal of the contents of elements with only whitespace. Thanks
+ Eric Wald for reporting.

+. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
+ tested on Linux.
+. Removed trailing whitespace from all text files, see
+ remote-trailing-whitespace.php maintenance script.
+. Convert configuration to use property list backend.
+
+3.2.0, released 2008-10-31
+# Using %Core.CollectErrors forces line number/column tracking on, whereas
+ previously you could theoretically turn it off.
+# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
+ use handleEnd() instead.
+! %Output.AttrSort for when you need your attributes in alphabetical order to
+ deal with a bug in FCKEditor. Requested by frank farmer.
+! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
+! Proper support for name attribute. It is now allowed and equivalent to the id
+ attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
+ is heavy (for all doctypes).
+! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
+ use on hand-written HTML.
+! Add error-cases for unsupported elements in MakeWellFormed. This enables
+ the strategy to be used, standalone, on untrusted input.
+! %Core.AggressivelyFixLt is on by default. This causes more sensible
+ processing of left angled brackets in smileys and other whatnot.
+! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
+ 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
+ the --only-phpt parameter, although for backwards-compatibility the flag
+ will still work.
+! AutoParagraph auto-formatter will now preserve double-newlines upon output.
+ Users who are not performing inbound filtering, this may seem a little
+ useless, but as a bonus, the test suite and handling of edge cases is also
+ improved.
+! Experimental implementation of forms for %HTML.Trusted
+! Track column numbers when maintain line numbers is on
+! Proprietary 'background' attribute on table-related elements converted into
+ corresponding CSS. Thanks Fusemail for sponsoring this feature!
+! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
+ supertype.
+! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
+ time of operation varies slightly from notifyEnd() as *all* end tokens are
+ processed by the injector before they are subject to the well-formedness rules.
+! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
+ basename of image when not present.
+! %AutoFormat.DisplayLinkURI neuters tags into plain text URLs.
+- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
+ the other involving an undefined $is_folder error.
+- Throw error when %Core.Encoding is set to a spurious value. Previously,
+ this errored silently and returned false.
+- Redirected stderr to stdout for flush error output.
+- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
+ available.
+- Do not re-munge URL if the output URL has the same host as the input URL.
+ Requested by Chris.
+- Fix error in documentation regarding %Filter.ExtractStyleBlocks
+- Prevent
]]> from triggering %Core.ConvertDocumentToFragment
+- Fix bug with inline elements in blockquotes conflicting with strict doctype
+- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
+- Fix bug where dots and double-dots in absolute URLs without hostname were
+ not collapsed by URIFilter_MakeAbsolute.
+- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
+ by reordering their addition.
+- Will now throw exception on many error conditions during lexer creation; also
+ throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
+ is being used.
+- Detect if domxml extension is loaded, and use DirectLEx accordingly.
+- Improve handling of big numbers with floating point arithmetic in UnitConverter.
+ Reported by David Morton.
+. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
+ for more interesting filter-backtracking
+. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
+ index to reprocess tokens.
+. StringHashParser now allows for multiline sections with "empty" content;
+ previously the section would remain undefined.
+. Added --quick option to multitest.php, which tests only the most recent
+ release for each series.
+. Added --distro option to multitest.php, which accepts either 'normal' or
+ 'standalone'. This supercedes --exclude-normal and --exclude-standalone
+
