  - 1024-bit moduli upgraded from warnings to failures.
  - Many Python 2 code clean-ups, testing framework improvements, pylint & flake8 fixes, and mypy type comments; credit [Jürgen Gmach](https://github.com/jugmac00)).
  - Suppress recommendation of token host key types.
- - Added 1 new host key type: `ssh-rsa1`.
+ - Added 2 new host key types: `ssh-rsa1`, `ssh-dss-sha256@ssh.com`.
  - Added 1 new key exchange: `diffie-hellman-group1-sha256`.
- - Added 3 new ciphers: `blowfish`, `AEAD_AES_128_GCM`, `AEAD_AES_256_GCM`.
- - Added 2 new MACs: `chacha20-poly1305@openssh.com`, `hmac-sha3-224`.
+ - Added 5 new ciphers: `blowfish`, `AEAD_AES_128_GCM`, `AEAD_AES_256_GCM`, `crypticore128@ssh.com`, `seed-cbc@ssh.com`.
+ - Added 3 new MACs: `chacha20-poly1305@openssh.com`, `hmac-sha3-224`, `crypticore-mac@ssh.com`.
 
 ### v2.2.0 (2020-03-11)
  - Marked host key type `ssh-rsa` as weak due to [practical SHA-1 collisions](https://eprint.iacr.org/2020/014.pdf).
