- When NVS encryption is enabled on SoCs with the HMAC peripheral that have flash encryption enabled, the HMAC-based NVS encryption scheme is now selected as default instead of the flash encryption-based scheme. - If your application previously used the flash encryption-based scheme, you need to manually configure the NVS encryption scheme to flash encryption from HMAC through ``menuconfig`` or your project's ``sdkconfig`` (i.e., setting ``CONFIG_NVS_SEC_KEY_PROTECT_USING_FLASH_ENC=y``).
