Migrating from WoltLab Suite 5.5 - Third Party Libraries#
Symfony PHP Polyfills#
The Symfony Polyfills for 7.3, 7.4, and 8.0 were removed, as the minimum PHP version was increased to PHP 8.1. The Polyfills for PHP 8.2 and PHP 8.3 were added.
Refer to the documentation within the symfony/polyfill repository for details.
The true/punycode and pear/net_idna2 dependencies were removed, because of a lack of upstream maintenance and because the
intl extension is now required.
idn_to_ascii function should be used.
Diactoros was updated from version 2.4 to 3.0.
WoltLab Suite 6.0 ships with cuyz/valinor 1.6 as a reliable solution to validate untrusted external input values.
Refer to the documentation within the CuyZ/Valinor repository for details.
WoltLab Suite 6.0 ships with sebastian/diff as a replacement for
wcf\util\Diff::rawDiffFromSebastianDiff() method was added as a compatibility helper to transform sebastian/diff's output format into Diff's output format.
Refer to the documentation within the sebastianbergmann/diff repository for details on how to use the library.
See WoltLab/WCF#4918 for examples on how to use the compatibility helper if you need to preserve the output format for the time being.
WoltLab Suite 6.0 ships with willdurand/negotiation to perform HTTP content negotiation based on the headers sent within the request.
wcf\http\Helper::getPreferredContentType() method provides a convenience interface to perform content negotiation with regard to the MIME type.
It is strongly recommended to make use of this method instead of interacting with the library directly.
In case the API provided by the helper method is insufficient, please refer to the documentation within the willdurand/Negotiation repository for details on how to use the library.
WoltLab Suite 6.0 ships with dragonmantank/cron-expression as a replacement for
This library is considered an internal library / implementation detail and not covered by backwards compatibility promises of WoltLab Suite.
The chrisjean/php-ico dependency was removed, because of a lack of upstream maintenance. As the library was only used for Favicon generation, no replacement is made available. The favicons are now delivered as PNG files.
