PHP官方組織正式釋出了PHP 4.4.0，除了將之前嚴重的xml.prc安全性問題在緊急釋出的測試版解決做一個更新外，最重要的是官方建議所有PHP用戶更新，已解決references方面的安全性漏洞，其他重要的更新是這些：
# Added man pages for "phpize" and "php-config" scripts.
# Added support for .cc files in extensions.
# Added the sorting flag SORT_LOCALE_STRING to the sort() functions which makes them sort based on the current locale.
# Changed sha1_file() and md5_file() functions to use streams instead of low level IO.
# Fixed memory corruptions when using references in a wrong way.
# Fixed memory corruption in pg_copy_from() in case the as_null parameter was passed.
# Fixed memory corruption in stristr().
