Prado 4.3.0 has been released!

October 26, 2023

This new release introduces a lot of new features and compatibility changes baked during the last year.

The required minimum Php version has been raised to 8.1; if you're still running php 7.x you should really consider upgrading, but in the meanwhile Prado 4.2.x will keep serving you well.

A big thank to @belisoful that worked hard to consolidate two basic aspects of prado: data type classes (TList/TMap/...) and behaviors, and also found the time to add some new goodies like an integrated PHP Web Server Action for built-in app development.

As always, before upgrading you may want to have a read at HISTORY.md to see what has changed in details and UPGRADE.md to check if your application needs any modification to run on this new Prado version.

Happy coding!

Prado 4.2.2 is available!

April 6, 2023

This is mainly a bug-fix and compatibility release.

The minimum required PHP version has been raised from 7.3 to 7.4. While this should be a simple update, please remember that PHP 7 is EOL (end of life), so you should consider upgrading to PHP 8.x as soon as possible.

For this reason this would probably be the last Prado version supporting PHP 7, as new development will only target PHP 8 from now on.

Many thanks to all the developers who contributed to this release, in particular we'd like to thank @belisoful for his continuous effort in implementing new features and keeping them updated.

Users are advised to update from 4.2.1, as it should require no code changes.

Happy coding!

November 18, 2019

Prado 4.1.0 is available!
This release is 100% compatible with existing code running on Prado 4.0.x, and a few minor fixes are included aswell.

The biggest change in this new version is that it requires at least Php 7.1 in order to run; later versions are supported and tested aswell.


If you're still running applications based on Php 5, you should really consider upgrading. Php 5 is officially out of support since an year ago, and Php 7 is a really solid upgrade in terms of speed and features.
