The PHP development team would like to announce the immediate availability of PHP 5.3.3. This release focuses on improving the stability and security of the PHP 5.3.x branch with over 100 bug fixes, some of which are security related. All users are encouraged to upgrade to this release.

Backwards incompatible change:

• Methods with the same name as the last element of a namespaced class name will no longer be treated as constructor. This change doesn't affect non-namespaced classes.

  <?php
namespace Foo;
class Bar {
    public function Bar() {
        // treated as constructor in PHP 5.3.0-5.3.2
        // treated as regular method in PHP 5.3.3
    }
}
?>

  There is no impact on migration from 5.2.x because namespaces were only introduced in PHP 5.3.

• Rewrote var_export() to use smart_str rather than output buffering, prevents data disclosure if a fatal error occurs (CVE-2010-2531).

PHP is proud to announce TestFest 2010. TestFest is PHP's annual campaign to increase the overall code coverage of PHP through PHPT tests. During TestFest, PHP User Groups and individuals around the world organize local events where new tests are written and new contributors are introduced to PHP's testing suite.

Last year was very successful with 887 tests submitted and a code coverage increase of 2.5%. This year we hope to do better.

TestFest's own SVN repository and reporting tools are back online for this year's event. New to TestFest this year are automated test environment build tools as well as screencasts showing those build tools in action.

Please visit the TestFest 2010 wiki page for all the details on events being organized in your area, or find out how you can organize your own event.
