## 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
