[openssl-users] SSL version status

[Nulik Nol]

Hi,
I have to implement SSL/TLS in a proprietary web server daemon. I am
only familiar with SSL as a user, not as developer, so my question is.
What versions of SSL should I support for best compatibility and
optimal development time? How much old browsers are out there that
still use older SSL versions? Because, Wikipedia says SSL 3.0 was
deprecated by Jun 2015 but if I only implement TLS, I may lose many
visitors with old browsers, right ?

Please advise.
TIA
Nulik
