Bugfix
+ * Properly initialize and free SHA-256 / SHA-512 context in entropy module
+ instead of performing zeroization only. This could lead to failure for
+ alternative implementations of SHA-256 / SHA-512 for which zeroization
+ of contexts is not a proper way of initialization.
+ Found and fix suggested by ccli8.
* Fix ssl_parse_record_header() to silently discard invalid DTLS records
as recommended in RFC 6347 Section 4.1.2.7.
* Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
