### Summary

Previous releases of OpenSSL (since Node.js v0.10.39, v0.12.5, v4.0.0 and v5.0.0) mitigated against [Logjam](https://en.wikipedia.org/wiki/Logjam_%28computer_security%29) for TLS _clients_ by rejecting connections from servers where Diffie-Hellman parameters were shorter than 768-bits.

The new OpenSSL release, for all Node.js lines, increases this to 1024-bits. The change only impacts TLS clients connecting to servers with weak DH parameter lengths.

## _(Update 30-Jan-3016)_ Release postponement

The announced security releases will not go ahead for the 1st of February as previously announced. Instead, our new target for release will be on or shortly after **Tuesday, the 9th of February, 11pm UTC** _(Tuesday, the 9th of February, 3pm Pacific Time)_.

The planned fixes include a backward-incompatible change that, under normal circumstances, would be deferred until the next major-version of Node.js, v6. However, because the fix addresses a security concern that exists across all release lines (including our LTS lines: v4, v0.12 and v0.10) we require the additional time to further review the changes and consider how best to achieve minimal impact to users.

We apologise for any inconvenience this schedule change may cause.

Please tune in to **nodejs-sec** (https://groups.google.com/forum/#!topic/nodejs-sec) to be notified of any further updates.
