it's not, Microsoft didn't release anything similar to Windows that would have 
"9" or "10" in the name (even DOS stopped at 6). But there was both SSLv2 and 
SSLv3.

It's closer to the RHL 7 (Red Hat Linux) being confused with RHEL 7 (Red Hat 
Enterprise Linux), and yes, it's still happening

the problem is not that people will not know when you talk about TLSv2.0 you 
mean TLSv1.3 (or vice versa). The problem is that people will think that when 
you talk about TLSv2.0 you mean SSLv2 *because* people use the SSL and TLS 
terms interchangeably!
