Why use OpenBSD when superior FreeBSD exists?
The version scheme still makes no sense, but I guess it's historical baggage by now. There's nothing in the release notes that introduces a breaking change to something which has been true for all of the 6.x releases. You could just call it OpenBSD 51 since it's the 51st release after the split from NetBSD.https://www.openbsd.org/70.html>Changed usage of %n from a syslog warning to syslog and abort for printf(3) (and associated variants). They don't want to you use a possibly insecure feature mandated by standard so hard that it crashes your program now.>OpenSSH 8.8: This release disables RSA signatures using the SHA-1 hash algorithm by default.Pretty recent versions of different SSH implementations such as PuTTY and libssh still only support ssh-rsa (using SHA-1, as specified in the initial RFC) over rsa-sha2-256/rsa-sha2-512 for host keys and public key auth, make sure to update them if you plan to upgrade your server and use RSA keys.
