    What has changed in PHP 5.2.x

    Most improvements in PHP 5.2.x have no impact on
    existing code. There are a few incompatibilities and new error
    messages
    that should be considered, and code should be tested
    before switching PHP versions in production environments.

    If the system is being upgraded from PHP 5.0.x, the
    manual section titled Upgrade Notes for PHP 5.1.x should also be read.

    Similarly, if the system is being upgraded from PHP
    4, the manual section titled Migrating from PHP 4 to PHP 5 should be read as
    well.
