| * Mbed TLS now supports TLS 1.3 key establishment via pre-shared keys. | |
| The pre-shared keys can provisioned externally or via the ticket | |
| mechanism (session resumption). | |
| The ticket mechanism is supported when the configuration option | |
| MBEDTLS_SSL_SESSION_TICKETS is enabled. | |
| New options MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_xxx_ENABLED | |
| control the support for the three possible TLS 1.3 key exchange modes. |
