Andrew Stitcher updated PROTON-2009:
------------------------------------
    Description: 
The OpenSSL SSL_OP_NO_TLSvxxx options are deprecated for use in 
SSL_CTX_set_options().

As of OpenSSL 1.1 way to specify TLS versions is through a min-version and 
max-version scheme - this is more code future proof.

You can specify a minimum version and 0 for the maximum meaning the latest 
version.

Proton's interface to this allows more than can be specified using the min/max 
API as you can specify each protocol individually.

The proton code is also not future proof in that it "knows" about each TLS 
protocol individually in the code.
