Migrating from WoltLab Suite 5.3 - Third Party Libraries#
The bundled Guzzle version was updated to Guzzle 7. No breaking changes are expected for simple uses. A detailed Guzzle migration guide can be found in the Guzzle documentation.
sink that was recommended in the migration guide for WoltLab Suite 5.2 can now be removed, as the Guzzle issue #2735 was fixed in Guzzle 7.
Emogrifier / CSS Inliner#
The Emogrifier library was updated from version 2.2 to 5.0.
This update comes with a breaking change, as the
Emogrifier class was removed.
With the updated Emogrifier library, the
CssInliner class must be used instead.
No compatibility layer was added for the
Emogrifier class, as the Emogrifier library's purpose was to be used within the email subsystem of WoltLab Suite.
In case you use Emogrifier directly within your own code, you will need to adjust the usage.
Refer to the Emogrifier CHANGELOG and WoltLab/WCF #3738 if you need help making the necessary adjustments.
If you only use Emogrifier indirectly by sending HTML mail via the email subsystem then you might notice unexpected visual changes due to the improved CSS support. Double check your CSS declarations and particularly the specificity of your selectors in these cases.
scssphp was updated from version 1.1 to 1.4.
If you interact with scssphp only by deploying
.scss files, then you should not experience any breaking changes, except when the improved SCSS compatibility interprets your SCSS code differently.
If you happen to directly use scssphp in your PHP code, you should be aware that scssphp deprecated the use of output formatters in favor of a simple output style enum.
Refer to WoltLab/WCF #3851 and the scssphp releases for details.
