  Today it is exactly three years ago since PHP 5 has been released. In

  The PHP development team hereby announces that support for PHP 4 will
  continue until the end of this year only. After 2007-12-31 there will be no
  more releases of PHP 4.4. We will continue to make critical security fixes
  available on a case-by-case basis until 2008-08-08.  Please use the rest of
  this year to make your application suitable to run on PHP 5.
</p>
  <p>

  For documentation on migration for PHP 4 to PHP 5, we would like to point you
  to our <a href="/manual/en/migration5.php">migration guide</a>. There is

  <p>
    The PHP team is once again proud to participate in the
    <a href="http://code.google.com/soc/">Google Summer of Code</a>.
    Seven students will "flip bits instead of burgers" this summer:

</p>
  <ul>
    <li>
        Mentored by Michael Wallner, Hannes Magnusson will work on
        <a href="http://wiki.phpdoc.info/LiveDocs">LiveDocs</a>, which is a
        "tool to display DocBook XML files in a web browser on the
        fly, without the need of building all HTML target files first".
        This project will be of great value to the PHP Documentation Team.
  </li>
    <li>
        The PHP Interpreter uses reference counting to keep track of which
        objects are no longer referenced and thus can be destroyed. A major
        weakness in the current implementation is that it cannot detect
        reference cycles, that is objects that reference each other in a
        circular graph structure which is not referenced itself from outside
        the circle. Mentored by Derick Rethans, David Wang will implement a
        new reference counting algorithm that will alleviate this problem.
  </li>
    <li><a href="http://xdebug.org/">Xdebug</a> provides a range of useful
        functionality for PHP developers, including detailed error information,
        code coverage and profiling support, and support for remote debugging
        using the GDB and DBGp protocols. Mentored by Xdebug's creator,
        Derick Rethans, Adam Harvey will develop a cross-platform GUI
        application that implements the DBGp protocol and allows PHP
        applications to be debugged using Xdebug in a development environment
        agnostic fashion.
  </li>

    <li>
	    Mentored by Lukas Smith, Konsta Vesterinen will work on the
        object-relational mapper <a href="http://www.phpdoctrine.net/">Doctrine</a>.
  </li>
    <li>
        Mutation Testing, or Automated Error Seeding, is an approach where
        the testing tool makes some change to the tested code, runs the tests,
        and if the tests pass displays a message saying what it changed. This
        approach is different than code coverage analysis, because it can find
        code that is executed by the running of tests but not actually tested.
        Mentored by Sebastian Bergmann, Mike Lewis will implement Mutation
        Testing for <a href="http://www.phpunit.de/">PHPUnit</a>.
  </li>
    <li>
        Mentored by Helgi Þormar Þorbjörnsson, Igor Feghali will add support
        for foreign keys to
        <a href="http://pear.php.net/package/MDB2_Schema/">MDB2_Schema</a>,
        a package that "enables users to maintain RDBMS independant schema
        files in XML that can be used to create, alter and drop database
        entities and insert data into a database".
  </li>

    <li>
        Mentored by David Coallier, Nicolas Bérard-Nault will refactor the
        internals of <a href="http://www.jaws-project.com/">Jaws</a>, a
        Framework and Content Management System for building dynamic web sites,
        for PHP 6.

The majority of the security vulnerabilities discovered and resolved can in
most cases be only abused by local users and cannot be triggered remotely.
However, some of the above issues can be triggered remotely in certain
situations, or exploited by malicious local users on shared hosting setups
utilizing PHP as an Apache module. Therefore, we strongly advise all users of
PHP, regardless of the version to upgrade to the 5.2.1 or 4.4.5 releases as soon as possible.
</p>
  <p>
For users upgrading to PHP 5.2 from PHP 5.0 and PHP 5.1, an upgrade guide is
available <a href="/migration52">here</a>, detailing the changes between
those releases and PHP 5.2.1.
</p>
  <p><strong>Update: Feb 14th;</strong> Added release information for PHP
4.4.5.</p>
  <p><strong>Update: Feb 12th;</strong> The Windows install package had problems
with upgrading from previous PHP versions. That has now been fixed and new file
posted in the <a href="/downloads.php">download section</a>.</p>

  <p>
    The news on the front page of php.net has changed, the <a href="/conferences/">conference announcements</a> are now located on their own page.
    The idea is to keep php.net specific news clear and also opens the door for additional news entries, like for RC releases. More changes are on the way so keep an eye out.
