 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).
+     ssl_ciphersuites.c). The preferred cipher suite is now
+     TLS_CHACHA20_POLY1305_SHA256.
 
 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.
+   * In the TLS 1.3 server, select the preferred client cipher suite, not the
+     least preferred. 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.
