All of these updates should be totally backward compatible, except one, CVE-2021-21395 - GHSA-r3c9-9j5q-pwv4 - Reset Password not protected against well-timed CSRF in fact is a breaking change and you will need to take action after upgrading to this version of OpenMage.
Specifically, you will have to modify the customer/form/resetforgottenpassword.phtml file of your custom theme (in case you have customized it) and add this code <input name="form_key" type="hidden" value="<?php echo $this->getFormKey(); ?>" /> after the <form open tag. Please refer to this link in case you want to see how the patch works and copy/paste the simple solution.
In case your custom theme does not have the customer/form/resetforgottenpassword.phtml or in case you are not using a custom theme then you will not have to do the aforementioned procedure.
