Contao 5.0.0, a new version of the Contao open source CMS, has been released.

In the eighties, crowds flocked to the cinema halls for Robot Number 5, which was struck by lightning. Almost 40 years later, a lot has changed, but it's a five again that stands for something big. The latest version of our favourite CMS has just landed. With your help, Contao 5 will write an unforgettable piece of software history. Have fun with the new arrival.

What can you expect from Contao 5?

During the development of the new major version, the focus this time was not on new features, but on getting rid of as much old code as possible. The so-called "BC layers" slow down the development of Contao and tie up a lot of resources. So Contao 5 is just a number. It is basically Contao 4.14 without ballast from older versions and therefore it must be labeled version 5.0 according to our versioning strategy.

You can read more about this in Yanick's detailed article on the developer meeting 2022.

Nevertheless, there are also new features in Contao 5. For example, the Contao install tool has been removed and moved completely to the Contao Manager.

Other improvements and changes for users:

  • Unification of the user interface for child elements.
  • Pages and files move under "Content"
  • No saving of incomplete content elements
  • New content element for unfiltered HTML
  • Contao core templates are based on TWIG

You can find a complete list of all changes in the changelog at the end of the blog post.

Extensions and Contao 5

Due to the clean-up in Contao 5, most extensions also need to be adapted to be compatible again. This means that you will hardly be able to install any extensions at the moment.

Depending on the effort, it may take a few weeks until the packages are fit for Contao 5 again and work without errors.

It is a good time to remember that for seven years now, little to no financial support was needed for the most popular extensions. This is precisely because the Contao core team has taken so much effort to always ensure backwards compatibility.

We have all been able to benefit from this for years. Now it is up to us to support the programmers financially and make sure that the ecosystem around the Contao core can be updated step by step.

Of course, all known trakked feature are also available for Contao 5.
