Release notes

Sourced from cakephp/cakephp's releases.

CakePHP 4.0.0 released

The CakePHP team is thrilled to announce the immediate availability of 4.0.0. This is release begins a new chapter for CakePHP as 4.0 is now API stable and the release windows for 2.x and 3.x begin.

Key Features

• PHP 7.2 required.
• Streamlined APIs with all deprecated methods and behavior removed.
• Additional typehints across the framework giving you errors faster.
• Improved error messages across the framework.
• A refreshed application skeleton design.
• New database types for fixed length strings (CHAR), datetime with
  microseconds, and datetime with timezone types.
• Table now features OrFail methods that raise exceptions on failure
  making error handling more explicit and straightforward.
• Middleware for CSP headers, Form tampering prevention, and HTTPS enforcement.
• Cake\Routing\Asset to make generating asset URLs simple from anywhere in
  your application code.
• FormHelper now generates HTML5 validation errors.
• FormHelper now generates HTML5 datetime input elements.

Upgrading to 4.0

While 4.0 contains a number of
breaking changes we have prepared an exhaustive migration guide covering all the deprecated, removed, and new features.

Additionally, we have put together an upgrade guide which gives a step-by-step guide and CLI tool to help you upgrade your application. These documents and companion tool will only improve as we collect more feedback from people upgrading.
