+ <p>
+ Separate client and server session cache internally.</p>
+ <p>
+ Avoid session table growth when client starts many
+ connections in such a manner that many connections are
+ started before session reuse is possible. Only save a new
+ session in client if there is no equivalent session
+ already stored.</p>
+ <p>
+ Own Id: OTP-11365</p>
+ </item>
+ <item>
+ <p>
+ The PEM cache is now validated by a background process,
+ instead of always keeping it if it is small enough and
+ clearing it otherwise. That strategy required that small
+ caches where cleared by API function if a file changes on
+ disk.</p>
+ <p>
+ However export the API function to clear the cache as it
+ may still be useful.</p>
+ <p>
+ Own Id: OTP-12391</p>
+ </item>
+ <item>
+ <p>
+ Add padding check for TLS-1.0 to remove Poodle
+ vulnerability from TLS 1.0, also add the option
+ padding_check. This option only affects TLS-1.0
+ connections and if set to false it disables the block
+ cipher padding check to be able to interoperate with
+ legacy software.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>
+ <p>
+ Own Id: OTP-12420</p>
+ </item>
+ <item>
+ <p>
+ Add support for TLS_FALLBACK_SCSV used to prevent
+ undesired TLS version downgrades. If used by a client
+ that is vulnerable to the POODLE attack, and the server
+ also supports TLS_FALLBACK_SCSV, the attack can be
+ prevented.</p>

+ Sockets Layer (SSL), are cryptographic protocols designed to
+ provide communications security over a computer network. The protocols use
+ use X.509 certificates and hence public key (asymmetric) cryptography to

+ and to exchange a symmetric key for payload encryption. The protocol provides
+ data/message confidentiality (encryption), integrity (through message authentication code checks)
+ and host verification (through certificate path validation).</p>
