Downloaded all portable #OpenSSH releases starting with 1.0pre2 to 9.9p2.
OpenSSH started shipping a pre-computed Diffie-Hellman key exchange group moduli file with 2.9.9. But it doesn't change on every release, like I thought it did.
The releases where the moduli file changed were:
- 2.9.9
- 3.8.1
- 4.0
- 4.9
- 6.0
- 6.1
- 6.2
- 6.9
- 7.0
- 7.3
- 7.4
- 7.7
- 7.8
- 7.9
- 8.0
- 8.1
- 8.2
- 8.3
- 8.4
- 8.5
- 8.6
- 8.7
- 8.9
- 9.1
- 9.2
- 9.4
- 9.6
- 9.8
- 9.9
Curious what sizes they shipped.
