PHP 4.0.6 has been released. Like 4.0.5, this is a maintenance release which mostly includes fixes to bugs and issues found in earlier versions. Those of you who decided not to upgrade to 4.0.5, may now wish to jump directly to 4.0.6 to get all the new fixes of both versions. One very important addition is the Japanese support through the new multibyte extension, that was ported from the PHP 3.0-jp code and improved by Rui Hirokawa. This makes PHP 4.0.6 the first version of PHP to have integrated support for Japanese in the standard distribution package, which is significantly better than the old solution of having a different version especially for Japanaese users. We hope that additional far-eastern languages will be supported in the future. Another major feature in 4.0.6 is the reduced memory requirements, thanks to a patch from Andi ([EMAIL PROTECTED]) that reduced memory fragmentation very significantly. Finally, the MySQL module now features the ability to use unbuffered queries, for reduced memory consumption when having large result sets. Look at mysql_unbuffered_query() for further details. A full list of changes is available below, and at http://www.php.net/ChangeLog-4.php. As with 4.0.5, we waited until the Windows binaries are built before announcing the availability of the new version. Thanks goes to Phil Driscoll ([EMAIL PROTECTED]) and Daniel Beulshausen ([EMAIL PROTECTED]) for providing the Win32 builds. To go on, point your browsers at http://www.php.net/downloads.php.
