CakePHP 4.0.0-beta1 Released

The CakePHP core team is proud to announce the first beta release of CakePHP 4.0.0. Since the previous alpha we’ve been hard at work converting the various Shell classes into Commands, and adapting to the most recent changes in psalm. If your application or plugins extend shell classes in CakePHP you will need to update your code.

The majority of breaking changes for 4.0 are complete. For the next beta release we’ll be focusing on improving stability, updating the remaining CakePHP managed plugins and continuing to improve error messages.

New Features The migration guide has a complete list of what’s new in 4.0.0. We recommend you give that page a read when upgrading as it notes the various breaking changes present in 4.0.

How you Can Help You can help deliver 4.0 by contributing in one of many ways: Check the documentation for mistakes, outdated, unclear or broken examples. We’ve been trying to update everything but may have not caught everything. Try it out! Give CakePHP 4.0 a test drive in a non-production application. We’d love to hear how converting a small application went and what was harder than it should have been. File issues for regressions in existing features, or suggest new features. While we’re not likely to greatly expand the scope of 4.0, we would like input on what should be a part of 4.1 and 4.2. Let us know about unclear error messages or silent failures in CakePHP.
