- Snap packages now print more user-friendly error messages when permission errors are encountered.
- JSON 'target' field now always includes port number; credit [tomatohater1337](https://github.com/tomatohater1337).
- Warnings are now printed for 2048-bit moduli.
- SHA-1 algorithms now cause failures.
- CBC mode ciphers are now warnings instead of failures.
- Generic failure/warning messages replaced with more specific reasons (i.e.: 'using weak cipher' => 'using broken RC4 cipher').
- Added 33 new host keys: `dsa2048-sha224@libassh.org`, `dsa2048-sha256@libassh.org`, `dsa3072-sha256@libassh.org`, `ecdsa-sha2-1.3.132.0.10-cert-v01@openssh.com`, `eddsa-e382-shake256@libassh.org`, `eddsa-e521-shake256@libassh.org`, `null`, `pgp-sign-dss`, `pgp-sign-rsa`, `spki-sign-dss`, `spki-sign-rsa`, `ssh-dss-sha224@ssh.com`, `ssh-dss-sha384@ssh.com`, `ssh-dss-sha512@ssh.com`, `ssh-ed448-cert-v01@openssh.com`, `ssh-rsa-sha224@ssh.com`, `ssh-rsa-sha2-256`, `ssh-rsa-sha2-512`, `ssh-rsa-sha384@ssh.com`, `ssh-rsa-sha512@ssh.com`, `ssh-xmss-cert-v01@openssh.com`, `ssh-xmss@openssh.com`, `webauthn-sk-ecdsa-sha2-nistp256@openssh.com`, `x509v3-ecdsa-sha2-1.3.132.0.10`, `x509v3-sign-dss-sha1`, `x509v3-sign-dss-sha224@ssh.com`, `x509v3-sign-dss-sha256@ssh.com`, `x509v3-sign-dss-sha384@ssh.com`, `x509v3-sign-dss-sha512@ssh.com`, `x509v3-sign-rsa-sha1`, `x509v3-sign-rsa-sha224@ssh.com`, `x509v3-sign-rsa-sha384@ssh.com`, `x509v3-sign-rsa-sha512@ssh.com`.
