+* **openssl**: Upgrade to 1.0.2e, containing fixes for:
+  - CVE-2015-3193 "BN_mod_exp may produce incorrect results on x86_64", an attack is considered feasible against DH, an attack against RSA and DSA is considered possible but unlikely, EC algorithms are not affected. Details are available at <http://openssl.org/news/secadv/20151203.txt>.
+  - CVE-2015-3194 "Certificate verify crash with missing PSS parameter", a potential denial-of-service vector for Node.js TLS servers; TLS clients are also impacted. Details are available at <http://openssl.org/news/secadv/20151203.txt>.

+### Known issues
+
+* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/node/issues/690)
+* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/node/issues/894)
+* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/node/issues/1435).
+* Unicode characters in filesystem paths are not handled consistently across platforms or Node.js APIs. See [#2088](https://github.com/nodejs/node/issues/2088), [#3401](https://github.com/nodejs/node/issues/3401) and [#3519](https://github.com/nodejs/node/issues/3519).
