The march of standards continues unabated. Legacy TLS protocols 1.0 and 1.1 have varying weaknesses that could lead to a false sense of security.
In June, in an effort to raise security and comply with modern standards, the insecure TLS 1.0 & 1.1 protocols will no longer be supported for SSL connections to Central. This should only affect users of Java 6 that are also using https to access central, which by our metrics is less than .2% of users.
At the same time, this conversion will allow Central to support HTTP/2 with potential performance gains for modern http clients.
If there is specific information required for non-maven build systems, please send it along and we will include that as well.
