v2.0.0

Changelog

2.0.0

Breaking changes

• PCGState shape changed to be JSON-serializable (#179, #330). The 64-bit
  state and streamId fields are now { hi: number, lo: number } objects
  (Uint64) instead of native bigints. Consumers that persisted v1.x state
  via JSON.stringify / structured clone must migrate; raw bigint state from
  v1.x will not round-trip.
• Public typings tightened (#240, #318, #319, #320). createPcg32's return
  type is now a nameable PCGState rather than an inferred anonymous type.
  Code that relied on the previous inferred shape may need to import
  PCGState explicitly.
• Minimum Node.js version is now 16. Declared via engines.node.

Performance

• ~7× faster randomInt / nextState / randomList hot path (#328).
• Scheme→increment dispatch moved into the PCG config (#331).

Fixes

• randomInt now allows a bound equal to outputMaxRange (#329).

Build / tooling

• Switched from tsc to tsup for dual ESM/CJS output (#317).
• Upgraded to TypeScript 6, ESLint 9 (flat config), and the Node 24 tsconfig
  base. CI matrix now covers Node 22 and 24.
