+Default behavior changes
+   * The default priority order of TLS 1.3 cipher suites has been modified to
+     follow the same rules as the TLS 1.2 cipher suites (see
+     ssl_ciphersuites.c).
+
+Bugfix
+   * In the TLS 1.3 server, select the prefered client cipher suite, not the
+     least prefered. The selection error was introduced in Mbed TLS 3.3.0.
+   * Fix TLS 1.3 session resumption when the established pre-shared key is
+     384 bits long. That is the length of pre-shared keys created under a
+     session where the cipher suite is TLS_AES_256_GCM_SHA384.
