Upgrading to 3.9.0

You can use composer to upgrade to CakePHP 3.9.0:

php composer.phar require --update-with-dependencies "cakephp/cakephp:3.9.*"

Deprecation Warnings

• ConsoleIo::info(), success(), warning() and error() will no longer accept null values in the message parameter in 4.0.
• Using a comma separated string for $fixtures in test cases is deprecated. Instead use an array, or implement the new getFixtures() method on your test case classes.
• Validator::errors() was renamed to Validator::validate().
• FormHelper::create() now emits deprecation warnings when the $context parameter is a boolean or string. These values trigger fatal errors in 4.0 and will need to be updated before upgrading.
• The magic method signature for FunctionBuilder::cast([...]) is deprecated. Use FunctionBuilder::cast('field', 'type') instead.
• Abandoned zendframework package has been replaced with laminas which provides backwards-compatible classes.

What’s new in 3.9.0?

The migration guide has a complete list of what’s new in 3.9.0. We recommend you give that page a read when upgrading. A few highlights from 3.9.0 are:

• Command classes can implement the defaultName() method to overwrite the conventions based CLI name.
• Query::orderAsc() and Query::orderDesc() now accept Closure’s as their field enabling you to use build complex order expressions with the provided QueryExpression object.
• Cake\Datasource\SimplePaginator was added. This class makes paginating very large results more efficient. It skips running the potentially expensive count() query. If you only use ‘next’ and ‘previous’ navigation in your pagination controls this class can be a good solution.
• Cake\Http\Client\Response::isSuccess() was backported from 4.0
• Cake\Http\Middleware\CspMiddleware was backported from 4.0
• BaseApplication::addOptionalPlugin() was added. This method handles loading plugins, and handling errors for plugins that may not exist because they are dev dependencies.
• The i18n global functions now only return strings. The changes made to 4.0 to remove the null return value when no translation string is provide have been backported to 3.9.
• Lenient parsing can be disabled for parseDateTime() and parseDate() using disableLenientParsing(). The default is enabled - the same as IntlDateFormatter.
• Table::saveManyOrFail() method has been added that will throw PersistenceFailedException with the specific entity that failed in case of an error. The entities are saved within a transaction.
• Table::deleteMany() and Table::deleteManyOrFail() methods have been added for removing many entities at once including callbacks. The entities are removed within a transaction.
• Text::uuid() now uses random_int() with PHP 5.6 insted of mt_rand(). This adds a dependency on paragonie/random_compat which implements it for PHP 5.6.
