### v3.1.0-dev (???)
- Added Python 3.12 to Tox tests.
- In server policies, reduced expected DH modulus sizes from 4096 to 3072 to match online hardening guides (note that 3072-bit moduli provide the equivalent of 128-bit symmetric security).
- In Ubuntu 22.04 client policy, moved host key types `sk-ssh-ed25519@openssh.com` and `ssh-ed25519` to the end of all certificate types.
### v3.0.0 (2023-09-07)
- Results from concurrent scans against multiple hosts are no longer improperly combined; bug discovered by [Adam Russell](https://github.com/thecliguy).
