The PHP development team is proud to announce the first beta release of PHP 5.4. PHP 5.4 includes new language features and removes several legacy (deprecated) behaviors. Windows binaries can be downloaded from the Windows QA site.

THIS IS A DEVELOPMENT PREVIEW - DO NOT USE IT IN PRODUCTION!

New features were added and bugs were fixed since alpha1. Please help us to identify bugs by testing new features and looking for unintended backward compatability breaks, so we can fix the problems and fully document intended changes before PHP 5.4.0 is released. Report findings to the QA mailing list and/or the PHP bug tracker.

Changes since the first alpha version include:

• Added callable typehint.
• Removed the timezone guessing algorithm. "UTC" is now used in case the timezone is not set.
• The mysql, mysqli and pdo_mysql extensions now use mysqlnd by default.

Read the NEWS file for a complete list of changes.

The PHP development team would like to announce the immediate availability of PHP 5.3.8. This release fixes two issues introduced in the PHP 5.3.7 release:

• Fixed bug #55439 (crypt() returns only the salt for MD5)
• Reverted a change in timeout handling restoring PHP 5.3.6 behavior, which caused mysqlnd SSL connections to hang (Bug #55283).

All PHP users should note that the PHP 5.2 series is NOT supported anymore. All users are strongly encouraged to upgrade to PHP 5.3.8.

For a full list of changes in PHP 5.3.8, see the ChangeLog. For source downloads please visit our downloads page, Windows binaries can be found on windows.php.net/download/.

For more details on the crypt() blowfish security issue in pre 5.3.6 see the crypt blowfish page

Due to unfortunate issues with 5.3.7 (see bug#55439) users should postpone upgrading until 5.3.8 is released (expected in a few days).

The PHP development team would like to announce the immediate availability of PHP 5.3.7. This release focuses on improving the stability of the PHP 5.3.x branch with over 90 bug fixes, some of which are security related.

Windows users: please mind that we do no longer provide builds created with Visual Studio C++ 6. It is impossible to maintain a high quality and safe build of PHP for Windows using this unmaintained compiler.

For Apache SAPIs (php5_apache2_2.dll), be sure that you use a Visual Studio C++ 9 version of Apache. We recommend the Apache builds as provided by ApacheLounge. For any other SAPI (CLI, FastCGI via mod_fcgi, FastCGI with IIS or other FastCGI capable server), everything works as before. Third party extension providers must rebuild their extensions to make them compatible and loadable with the Visual Studio C++9 builds that we now provide.

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.
