      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.
+   * Fix a bug in the record decryption routine ssl_decrypt_buf()
+     which lead to accepting properly authenticated but improperly
+     padded records in case of CBC ciphersuites using Encrypt-then-MAC.
    * Fix wrong order of freeing in programs/ssl/ssl_server2 example
      application leading to a memory leak in case both
      MBEDTLS_MEMORY_BUFFER_ALLOC_C and MBEDTLS_MEMORY_BACKTRACE are set.

    * Close a test gap in (D)TLS between the client side and the server side:
      test the handling of large packets and small packets on the client side
      in the same way as on the server side.
+   * Change the dtls_client and dtls_server samples to work by default over
+     IPv6 and optionally by a build option over IPv4.
