       MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
     * Fix a bug in the update function for SSL ticket keys which previously
       invalidated keys of a lifetime of less than a 1s. Fixes #1968.
+    * Zeroize memory used for reassembling handshake messages after use.
+    * Use `mbedtls_zeroize()` instead of `memset()` for zeroization of
+      sensitive data in the example programs aescrypt2 and crypt_and_hash.
 
 Changes
    * Add tests for session resumption in DTLS.
