The only change between 0.80 and 0.81 is one security fix:
- ECDSA signatures using 521-bit keys (the NIST P521 curve, otherwise
known as ecdsa-sha2-nistp521) were generated with biased random
numbers. This permits an attacker in possession of a few dozen
signatures to RECOVER THE PRIVATE KEY.
Any 521-bit ECDSA private key that PuTTY or Pageant has used to
sign anything should be considered compromised.
This vulnerability has the identifier CVE-2024-31497.
