| API changes | |
| * The PSA and Mbed TLS error spaces are now unified. mbedtls_xxx() | |
| functions can now return PSA_ERROR_xxx values. | |
| There is no longer a distinction between "low-level" and "high-level" | |
| Mbed TLS error codes. | |
| This will not affect most applications since the error values are | |
| between -32767 and -1 as before. | |
| Removals | |
| * Remove mbedtls_low_level_strerr() and mbedtls_high_level_strerr(), | |
| since these concepts no longer exists. There is just mbedtls_strerror(). |
