Changes you must know and that you have to check one by one

• PHP8.2 is now the minimum required version for OM v21
• Added form key validation to Contacts form
  Check app/design/frontend/base/default/template/contacts/form.phtml in your theme and be sure that you've <?php echo $this->getBlockHtml('formkey') ?> under the <form opening tag, as shown here.
• Unified CSRF configuration
  If you enabled CSRF in System -> Configuration -> System (which you should!) then it will be enabled for all your forms and the checkout.
• Removed double span element from HTML buttons
  Be sure to check your CSS styles for the buttons in your frontend theme, you may need to adjust them slightly.
• Removed all deprecated _Mysql4_ classes
  This will break many extremely old modules but it was long overdue and allowed us to remove 500+ obsolete files from the core. We provide the shell/rename-mysql4-class-to-resource.php migration script to fix the old modules, you will have to run it but make sure you'll do it in a test environment and thoroughly test everything before publishing to production.
• Removed decorate*() js functions
  Check the phtml files of your custom themes for javascript code calling decorate*() (decorateList, decorateTable, decorateGeneric etc) and remove those calls since they will generate javascript errors on your browser's console.
• Removed "admin routing compatibility mode" for extensions
  The new admin routing mode was implemented in Magento 1.4 for security reasons, together with "compatibility mode" (in order to allow some time to developers to update their modules). After these many years we are removing the compatibility mode and all extensions will have to follow the new admin routing mode or they will not appear in the backend.
• Removed scriptaculous/dragdrop.js from frontend
