thunder
A distribution for professional publishing
by Hubert Burda Media
Thunder is a Drupal distribution for professional publishing. It consists of the current Drupal functionality, lots of handpicked publisher-centric modules with custom enhancements, and an environment that makes it easy to install, deploy and add new functionality.
As members of the Thunder Coalition, publishers, industry partners, and developers build custom extensions and share them with the Coalition to further enhance Thunder.

Installation GuideAbout Thunder 6
Compared to the previous version Thunder 3, relatively few changes have been made in order to make updating as easy as possible. Since December 2019 the Thunder Core Team has been busy checking all modules used in Thunder for deprecations, solved them, and thus prepared all modules for Drupal 9.
Unfortunately, this did not succeed with two modules. So, this is actually the biggest change Thunder 6 brings you: We had to remove the modules Accelerated Mobile Pages (AMP) and Facebook Instant Articles from the distribution (at least for now). If these modules are in use on your site, we recommend that you do not install Thunder 6 and stay on Thunder 3 for the time being.

Multiple Thunder versions mean various levels of support
Since 2019, several Thunder versions exist side by side and are maintained by us. Here's an overview of current versions and releases:
Thunder 6
Thunder 6.x is based on Drupal 9. There will be new features released in this version, and the Thunder team will take care of security patches and critical bug fixes. The Thunder team will likely support this version until November 2023 when Drupal 9 will probably be discontinued.
We will always support the two latest versions: With every new Drupal minor version, we will also release a new Thunder version that will be fully supported. The older minor version will stay at security and bugfix support. Versions older than this won’t be supported anymore.
