Doc Text:	The TLS extensions that were sent in the Datagram TLS (DTLS) ClientHello requests did previously not contain the list of the supported elliptic curves. As a consequence, the DTLS connections to servers using elliptic curves not supported by the OpenSSL client were aborted. With this update, the elliptic curve list extension is properly sent in the DTLS ClientHello requests, and DTLS connections are no longer aborted in the above circumstances.	Story Points:	---

Description Tomas Mraz 2014-07-15 14:37:41 UTC

ECC supported curves list extension is missing in DTLS1 client hello message. Because we do not support all of the ECC curves that are currently widely used this severally worsens the interoperability of DTLS1 protocol in our openssl package.

Upstream recently fixed this issue.
