Magento 2.4.4 version was released on April 12, 2022. Overall it contain 240+ quality fixes and improvements. Its most important change is PHP 8.1 support. It includes all project libraries and dependencies. Another important thing is that it contain backward-incompatible changes. Magento team added a lot of hotfixes to improve security and patch known vulnerabilites. All vendor-bundled extensions have been removed from the codebase. Now you should install them from Marketplace.
Backward Incompatible Changes
The most important changes are following:
Removal of deprecated email variable usage.
Email variables was deprecated in earlier release. Currently its support completely removed. If you are still using newsletter templates that depends on variables – it wont work correctly anymore. Check Migrating custom email templates docs for additional information and possible ways to resolve it.
Language package filenames
2.4.4 and its support for PHP 8.1 requires changes in how translation packages are named. Language package filenames must now follow the naming conventions enforced by PHP 8.1. Consequently, lowercase letters are no longer permitted in the second part of the locale name.
Inventory check on cart load
A new “Enable Inventory Check On Cart Load” system configuration option has been added to Admin > Stores > Configuration > General > Catalog > Inventory > Stock Options. The new option determines if an inventory check is performed when loading a product in the cart. It is enabled by default. Disabling the inventory check can improve performance for checkout steps, especially when there are many items in the cart. But if this inventory check is skipped, some out-of-stock scenarios could throw other types of errors.
