Phalcon v4.0.0-alpha4 released

Read time: 2 minutes

The Phalcon Team is happy to announce the release of v4.0.0 Alpha 4! Github Tag. We also made a mistake yesterday in our hangout, PSR-7/PSR-17 related components were not released with alpha.3; the PR was actually merged after that release. Therefore we are releasing alpha.4 today!

As always, we cannot thank your community enough! As mentioned in yesterday’s hangout, our community rocks! We have more and more people joining our Discord server, contributors are helping with minor and major issues on all repositories. Our community is the drive that makes Phalcon better with every release.

We are releasing the fourth alpha version today, a lot of additions as well as bug fixes. You can see our project here

The biggest addition in this release is the PSR-7/PSR-17 compatible components under the Phalcon\Http\Message namespace.

Most likely, this will be the last alpha release, but it will depend primarily on the progress of the PSR-16 (Cache) implementation.

  • Added Phalcon\Http\Message\* namespace implementing PSR-7 and PSR-17. Introducing:
    • Phalcon\Http\Message\Request

    • Phalcon\Http\Message\Response
    • Phalcon\Http\Message\ResponseFactory

  • Refactored almost all files of the project to abide by the new coding standard for Phalcon. Certain files have been intentionally left untouched because they will be relaced later on. #13915
