Version 4.0.4.2 Release Notes

Improvements

The 4.0.4.2 release resolves an issue that could cause intermittent browsing interruptions for some customers.

Note: All 4.0.x release contain updated cipher suites to further improve security of HTTPS communications. SSLv3 was disabled in the 3.9.2.1 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.
