UPDATE 2011-08-22: See this post about a bug in crypt() in 5.3.7. PHP.net is recommending that you not upgrade to 5.3.7, but instead wait for 5.3.8.
PHP.net announced today that PHP version 5.3.7 has been released. I’m not sure if this is old news or not, but I also saw in the announcement that “all PHP users should note that the PHP 5.2 series is NOT supported anymore. All users are strongly encouraged to upgrade to PHP 5.3.7.” The major fixes/enhancements are:
