@ -8,6 +8,8 @@ Features
(ECDHE-based ciphersuites)
* Ability to specify allowed ciphersuites based on the protocol version.
* PSK and DHE-PSK based ciphersuites added
* Memory allocation abstraction layer added
* Buffer-based memory allocator added (no malloc() / free() / HEAP usage)
Changes
* Introduced separate SSL Ciphersuites module that is based on
