(node:54764) DeprecationWarning: Using Buffer without `new` will soon stop working. Use `new Buffer()`, or preferably `Buffer.from()`, `Buffer.allocUnsafe()` or `Buffer.alloc()` instead.

The fix is to simply change connection.js:299 from:

var emptyBuffer = Buffer(0);

To:

var emptyBuffer = Buffer.alloc(0);

Please check the existing issues before reporting a new one.

You are correct. I will exercise more caution in the future. I think I must have had the "is:open" filter on the issue.
