TLS version SPP 7.0.5 LTS

I am trying to figure out the TLS connection between a MySQL server and SPP when doing a 'test connection'. At the moment I have wireshark on the mysql server side to check and it look like the connection is TLS1.2. Is there any documentation to support what TLS version SPP uses? It may be that it supports up to and including TLS1.2, but I'm basing this on the SPS admin guides.
