+1.4 Register long Arrays ($HTTP_*_VARS)
+    -----------------------------------
+
+register_long_arrays and the long versions of super globals had been removed.
+PHP will emit E_CORE_ERROR during PHP startup if it would detect
+register_long_arrays setting.
+
+You can emulate long arrays by including the following file:
+
+<?php
+if (!ini_get('register_globals')) {	
+	$HTTP_POST_VARS =& $_POST;
+	$HTTP_GET_VARS =& $_GET;
+	$HTTP_COOKIE_VARS =& $_COOKIE;
+	$HTTP_SERVER_VARS =& $_SERVER;
+	$HTTP_ENV_VARS =& $_ENV;
+	$HTTP_FILES_VARS =& $_FILES;
+}
+?>
+
+1.5 ZE1 compatibility mode
+    ----------------------
+
+ZE1 compatibility mode (PHP4 object model) was introduced to migrate from PHP4
+to PHP5 in an easier way, but it never keeped 100% compatibility.
+It is completly removed in PHP6, and there is no way to emulate it.
+Applications should assume PHP5/PHP6 object model.
+
+1.6 dl() function
+    -------------
+
+Now dl() function is supported only in CLI, CGI and EMBED SAPI.
+There is no way to emulte it. You can just check if dl() is supported by SAPI:
+
+<?php
+if (!function_exists("dl")) {
+	die("dl() function is required\n!");
+}
+?>
+    
+1.7 E_ALL and E_STRICT constants
+    ----------------------------
+
+Now E_ALL error reporting mask includes E_STRICT.
+You can filter E_STRICT error messages using the following code:
+
+<?php
+error_reporting(error_reporting() & ~E_STRICT);
+?>
