Support for SSLv2 has been disabled
SSLv2 is insecure and should not be used in current deployments, and thus has been disabled without a way to override. All modern browsers and frameworks cannot negotiate SSLv2 connections in default configuration and many cannot be configured to perform SSLv2 negotiation. A recent OpenSSL vulnerability (CVE-2015-3197) shows that keeping this code is a liability. In addition, upstream has already removed support for SSLv2 (MZBZ#1228555).
