-   * To avoid dropping an entire DTLS datagram if a single record in a datagram
-     is invalid, we now only drop the record and look at subsequent records (if
-     any are present) in the same datagram to avoid interoperability issues.
-     Previously the library was dropping the entire datagram, Where a record is
-     unexpected, the function mbedtls_ssl_read_record() will now return
-     MBEDTLS_ERR_SSL_UNEXPECTED_RECORD.
+   * Fix suboptimal handling of unexpected records that caused interop issues
+     with some peers over unreliable links. Avoid dropping an entire DTLS
+     datagram if a single record in a datagram is unexpected, instead only
+     drop the record and look at subsequent records (if any are present) in
+     the same datagram. Found by jeannotlapin. #345
