@ -46,6 +46,8 @@ Changes
* Disabled SSLv3 in the default configuration.
* Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey
Skalozub).
* Fix non-compliance server extension handling. Extensions for SSLv3 are now
ignored, as required by RFC6101.
= mbed TLS 2.2.1 released 2016-01-05
