Upgrading to 1.1.23
Version 1.1.23 provides PHP 8.2 compatibility.
When updating the Hyvä Theme, always update the hyva-themes/magento2-theme-module package to its latest version. This is safe even if you are not updating the Default Theme to 1.1.23.
Backward incompatible changes
Previously, the class property \Hyva\Theme\Plugin\FrontController\HyvaHeaderPlugin::$theme was undeclared, treated as a dynamic public property. It is now declared with private visibility.
Technically, this is a backward compatibility-breaking change, as any child class referring to this parent class property will no longer work.
However, this scenario is believed to be unlikely. A simple workaround is to declare and assign the property in the child class as well.
