# Changelog ## 0.1.3 (2026-01-04) * Performance improvements: - Cache `KeyAggContext` in `SessionContext` to avoid redundant EC operations - Replace lazy `foldl` with strict `foldl'` to prevent space leaks - Add strictness annotations to `SessionContext` fields - Replace O(n) list indexing with O(log n) `Seq.lookup` in `partialSigVerify` - Optimize `integerToBytes32` to eliminate intermediate list allocation - Fix `NFData` instances in benchmarks for accurate measurements ## 0.1.2 (2025-12-30) * Fix Hackage build failure by implementing `modQ` locally to support `ppad-secp256k1` 0.5.0+. ## 0.1.1 (2025-12-22) * Bump `ppad-secp256k1` to 0.5.0. More efficient and faster EC operations. ## 0.1.0 (2025-09-20) * Initial release, full BIP-0327 support except [Deterministic and Stateless Signing for a Single Signer](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki#user-content-Deterministic_and_Stateless_Signing_for_a_Single_Signer)
