Promote with Leviathan NewsZcash Foundation's FROST v3.0.0 landed April 23 with tighter memory-safety discipline: signing keys and DKG round-two packages now auto-wipe when dropped, closing a subtle leak vector for operators running FROST in multi-party custody. The release also fixes verify_signature_share to properly call the pre_commitment_aggregate hook that slipped through in the release candidate, and makes min_signers optional on PublicKeyPackage so you can deserialize older serialized packages without choking.
