PHP 5.4.0 Release Announcement

The PHP development team is proud to announce the immediate availability of PHP 5.4.0. This release is a major leap forward in the 5.x series, and includes a large number of new features and bug fixes.

The key features of PHP 5.4.0 include:

  • New language syntax including Traits, shortened array syntax and more
  • Improved performance and reduced memory consumption
  • Support for multibyte languages now available in all builds of PHP at the flip of a runtime switch
  • Built-in webserver in CLI mode to simplify development workflows and testing
  • Cleaner code base thanks to the removal of multiple deprecated language features
  • Many more improvements and fixes

Changes that affect compatibility:

Extensions moved to PECL:

PHP 5.4 will be the last series to support Windows XP and Windows 2003. We will not provide binary packages for these Windows versions after PHP 5.4.

For users upgrading from PHP 5.3 there is a migration guide available here, detailing the changes between PHP 5.3 and PHP 5.4.0.
