My 2 cents... <p> As of XX-XX-2007, it will have been 3 years since the release of PHP 5. In these 3 years many improvements have been implemented over PHP 4 and PHP 5 can now be considered fast, stable & production ready. With PHP 6 in active development PHP 4 development will now be discontinued. </p> <p> Hereby the PHP development team announces that support for PHP 4 will be discontinued as of 2007-12-31, after this date there will be no more releases of PHP 4.4. Security issue's found in PHP 4.4 after this date will be evaluated for severity and the development team will consider relasing security updates until 2008-08-08. Please use the rest of this year to make your application suitable to run on PHP 5. </p>
