0.2.0 31 Jul 2026
Release notes
- SECURITY: bitsToInt now truncates using the order's byte length and applies the excess right-shift (previously discarded as a no-op), fixing hash/nonce derivation for curves whose order is not byte-aligned.
- SECURITY: the randomized signature() now produces low-S signatures (BIP-62) to avoid signature malleability.
- Allow elliptic 0.4.x, which provides constant-time (Montgomery-ladder) scalar multiplication.
