Version Release Notes


The release resolves several issues, and provides improved stability and performance.

Note: All 4.0.x release contain updated cipher suites to further improve security of HTTPS communications. SSLv3 was disabled in the release (October 2014) to protect against CVE-2014-3566 (POODLE). Subsequent updates have addressed CVE-2014-0160 (Heartbleed), CVE-2015-4000 (Logjam), and other OpenSSL vulnerabilities. If you have SSL scanning enabled, your outgoing connections will be made using TLS1.0 and not SSLv3. This may render some legacy websites unusable.
