Dear SSL care takers and stake holders, trunk has TLSv1.3 support for some time. I just now changed the 'all' SSLProtocol selection, so that it does not include TLSv1.3. This means that in order to enable it, admins must add an explicit '+TLSv1.3' to their config (same for SSLProxyProtocl of course).
With this, the added support is really an opt-in and we could backport it to 2.4.x, if we want. We have been burned with backporting SSL features just recently (by my mistake), so I would understand that people feel a bit reluctant here. On the other hand, there is certainly interest by users. So, what is your opinion? Cheers, Stefan PS. There are some combinations in renegotiation/client certs that are not tested well. Therefore, '+TLSv1.3' should be tagged as 'experimental' or at least with a heavy caveat for those setups. But I see no issue with using it for plain-vanilla https: setups.
