tl;dr: politics.

I still like to occasionally refer to TLS 1.3 as "SSL 3.4" to see whether people are aware of the history.

When TLS 1.3 was finally standardized, there was quite a bit of debate about whether in light of the how different it was from TLS 1.2 we should continue to use the 1.3 version number. ISTR that TLS 2 and TLS 4.0 were both floated--though I don't recall SSL 3.4--but eventually the WG decided to stick with the 1.3 version number we had been using throughout the rest of the process.

  • The version number in the protocol for TLS 1.3 is 03 04. TLS 1.0 is 03 01, and SSL 3.0 is 03 00. Hence "SSL 3.4".

    • Yes, I understood your reasoning. I'm just saying that I don't think anyone floated calling it SSL 3.4.
