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.

Security Enhancements and Fixes in PHP 5.3.3:

* Rewrote var_export() to use smart_str rather than output buffering, prevents data disclosure if a fatal error occurs (CVE-2010-2531).
* Fixed a possible resource destruction issues in shm_put_var().
* Fixed a possible information leak because of interruption of XOR operator.

* Fixed a possible memory corruption in parse_str().
* Fixed a possible memory corruption in pack().
* Fixed a possible memory corruption in substr_replace().
* Fixed a possible memory corruption in addcslashes().
* Fixed a possible stack exhaustion inside fnmatch().
* Fixed a possible dechunking filter buffer overflow.
* Fixed a possible arbitrary memory access inside sqlite extension.
* Fixed string format validation inside phar extension.
* Fixed handling of session variable serialization on certain prefix characters.
