Key Features in TYPO3 V12 LTS

Integrations

TYPO3 v12 LTS offers incoming and outgoing webhooks to securely exchange data between different applications in an enterprise environment. These webhooks are used to trigger the predefined actions and responses in an automated yet standardized way.

To make it easier for you, the new update brings in a better backend module where you can configure incoming webhooks as Reactions and integrate the system in a low-code environment.

 

 

Similarly, the outgoing webhooks are used to notify the external system of any changes made to TYPO3 and trigger follow-up actions. You can choose to list and manage the reactions as well as manage the outgoing webhooks, as seen below in the image.

Backend Enhancements

TYPO3 has recently introduced significant updates to its backend module, which provides a more efficient and user-friendly interface for editors, integrators, and developers.

Starting with the user interface that looks much cleaner and has a modern look to it. The new tiles view and drag-and-drop functions make file management more accessible, while the instant search feature allows users to find specific content faster.

For editors, the new and upgraded CKEditor comes with new features that make it easier to edit content for a TYPO3 site.

Integrators will love the number of customization options available on the backend, including customizing action buttons, simplified user management settings, and reworked backend modules for editing and managing TypoScript and Page TSconfig.

As a developer, you can gain more insights through System ➜ Configuration into Symfony Expression Language Providers, TCA configuration, and YAML configuration, offering greater control and flexibility.

Superpowers Under the Hood

TYPO3 uses the superpower based on Symfony Messenger, where the new message bus and message queue built into TYPO3's core enables the outgoing webhooks to work seamlessly.

Moreover, the queue system also includes an asynchronous mode to handle time-consuming tasks more efficiently.

Another addition has been made to TypoScript and Page TSconfig functions by the core team where they introduced a new TypoScript syntax parser that is much faster, more robust, and more logical than its predecessor.

Changes for Developers

There have been some massive changes offered for the developers working on TYPO3 in this version.

The latest version is compatible with both PHP 8.1 and 8.2 versions. These offer better performance overall, deprecated dynamic properties, and more.

You can see significant changes to third-party libraries and dependent packages, including the Database Abstraction Layer (DBAL), which uses Doctrine DBAL version 3, and the Table Configuration Array (TCA), which features several new types such as email, password generator, link, etc.

Furthermore, you can also see updates with the Extbase programming framework with the introduction of new methods like findBy(), findOneBy(), and count().

Internationalization

As seen in the previous TYPO3 v12 versions, TYPO3 v12 LTS talks about internationalization. In this version, you can easily create a new website language with a few simple steps.

Furthermore, the CountryAPI allows developers and other users in the backend to retrieve any country names, ISO codes, etc.

Strengthening the Security Posture

The main aspect of this update and release is Security and stability. TYPO3 v12 LTS introduces Content Security Policies (CSP) to improve security by detecting and mitigating attacks such as cross-site scripting and data injection.

You can check out the new module under Admin Tools as Content Security Policy, where all the recent potential CSP violations in the front end and back end of your site can be reviewed. It also has certain solutions available that allow you to fix them.

Furthermore, TYPO3 offers configurable password policies that spring into action during the system installation when creating the initial administrator user.
