5.2 Migration Guide

The 5.2.0 release is a backwards compatible with 5.0. It adds new functionality and introduces new deprecations. Any functionality deprecated in 5.x will be removed in 6.0.0.

Behavior Changes

  • ValidationSet::add() will now raise errors when a rule is added with a name that is already defined. This change aims to prevent rules from being overwritten by accident.

  • Http\Session will now raise an exception when an invalid session preset is used.

  • FormProtectionComponent now raises Cake\Controller\Exception\FormProtectionException. This class is a subclass of BadRequestException, and offers the benefit of being filterable from logging.

Deprecations

Console

  • Arguments::getMultipleOption() is deprecated. Use getArrayOption() instead.

New Features

  • Arguments::getArrayArgumentAt(), and Arguments::getArrayArgument() were added. These methods allow you to read separator delimitered positional arguments as arrays.
