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).

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.

The PHP development team is proud to announce the first PHP 5.4 alpha release. PHP 5.4 includes new language features and removes several legacy (deprecated) behaviors. Read the NEWS file for a complete list of changes.

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

This alpha release exists to encourage users to identify bugs, and to ensure that all new features and backward compatibility breaks are evaluated and documented before PHP 5.4.0 is released. Please report findings to the QA mailing list and/or the PHP bug tracker. Windows binaries can be downloaded from the Windows QA site.

Here is an incomplete list of changes:

• Added: Traits language construct
• Added: Array dereferencing support
• Added: DTrace support
• Improved: Improved Zend Engine memory usage and performance
• Moved: ext/sqlite moved to pecl (sqlite3 support is still built-in)

Please note that some legacy features have been removed, including:

• Removed: break/continue $var syntax
• Removed: register_globals, allow_call_time_pass_reference, and register_long_arrays ini options
• Removed: session_is_registered(), session_registered(), and session_unregister()

This is the first release that adopts the releaseprocess RFC. The next alpha will be released within four weeks. The PHP 5.4 feature set and API has not been finalized.

PHP has several new documentation features that the community should be aware of:

• pman - PHP man pages
  • $ pear install doc.php.net/pman
  • $ pman strlen (this example displays a local textual version of the strlen docs)
• Enhanced CHM - contains user notes (over 25,000)
  • This additional CHM file is downloadable
• Online Documentation Editor - allows everyone to edit the PHP manual
  • URL: https://edit.php.net/
  • Every manual page will link to it in the future
  • Includes an IRC window to the #php.doc channel, so let's talk

We hope you find the above features useful, and please write phpdoc@lists.php.net with feedback. Additional features are being refined, which includes a JSON version of the manual.

The wiki.php.net box was compromised and the attackers were able to collect wiki account credentials. No other machines in the php.net infrastructure appear to have been affected. Our biggest concern is, of course, the integrity of our source code. We did an extensive code audit and looked at every commit since 5.3.5 to make sure that no stolen accounts were used to inject anything malicious. Nothing was found. The compromised machine has been wiped and we are forcing a password change for all svn accounts.

We are still investigating the details of the attack which combined a vulnerability in the Wiki software with a Linux root exploit.

The PHP development team would like to announce the immediate availability of PHP 5.3.6. This release focuses on improving the stability of the PHP 5.3.x branch with over 60 bug fixes, some of which are security related.

The PHP development team would like to announce the immediate availability of PHP 5.3.5 and 5.2.17.

This release resolves a critical issue, reported as PHP bug #53632 and CVE-2010-4645, where conversions from string to double might cause the PHP interpreter to hang on systems using x87 FPU registers.

The problem is known to only affect x86 32-bit PHP processes, regardless of whether the system hosting PHP is 32-bit or 64-bit. You can test whether your system is affected by running this script from the command line.

All users of PHP are strongly advised to update to these versions immediately.
