| Default behavior changes | |
| * In the experimental PSA secure element interface, change the encoding of | |
| key lifetimes to encode a persistence level and the location. Although C | |
| prototypes do not effectively change, code calling | |
| psa_register_se_driver() must be modified to pass the driver's location | |
| instead of the keys' lifetime. If the library is upgraded on an existing | |
| device, keys created with the old lifetime value will not be readable or | |
| removable through Mbed TLS after the upgrade. |
