@ -10,6 +10,8 @@ Bugfix
* Fix mbedtls_x509_crt_profile_suiteb, which used to reject all certificates
with flag MBEDTLS_X509_BADCERT_BAD_PK even when the key type was correct.
In the context of SSL, this resulted in handshake failure. #1351
* In test_suite_pk pass valid parameters when testing for hash length
overflow. #1179
= mbed TLS 2.1.10 branch released 2018-02-03
