Upgrading to 4.3.0

You can use composer to upgrade to CakePHP 4.3.0:

Deprecation Warnings

4.3 introduces a few deprecations. All of these features will continue for the
duration of 4.x but will be removed in 5.0. See the migration guide.

What’s new in 4.3.0?

The migration guide has
a complete list of what’s new in 4.3.0. We recommend you give that page a read
when upgrading. A few highlights from 4.3.0 are:

A new fixture system that allows you to use your existing migrations or SQL
dump files to define schema was added. Support for cake’s migrations and SQL
dump files is included.
TestSuiteHttpMockTrait was added to make mocking HTTP client requests
easier.
LocatorAwareTrait::fetchTable() was added to make the
getTableLocator()->get() pattern more ergonomic.
Controller::middleware() was added. This method lets you define middleware
specific to a controller, or the current controller action.
deprecationWarning() no longer emits duplicate warnings.
Logged SQL queries now use boolean literals making them easier to paste into
a repl.
The cake console command was extracted into a new cakephp/repl
package.
Form objects now support multiple validators and leverage a similar
interface to the ORM to use those validators.
CspMiddleware can now transparently add nonce- based policies.
FormHelper will now set additional ARIA attributes automatically.
The ORM can now marshall date times from the user’s timezone into the
applications timezone transparently.
CakePHP’s dependency on league/container was bumped to ^4.1.1.
