v2.0.0

2.0.0 (2026-07-06)

⚠ BREAKING CHANGES

• _preStake / _preWithdraw / _preDistribute are removed. _stake, _withdraw, _distribute now accept uint128 liquidity directly, so consumers must narrow (e.g. via SafeCast.toUint128) at the external boundary. InsufficientStake is renamed to InsufficientLiquidity and now carries the raw uint256.

Features

• remove pre-hooks; internal API now takes uint128 directly (d05708a)

Documentation

• assorted README + CONTRIBUTING polish (f14814b)

v1.0.1

Fixed

• Dropped remappings.txt from the published npm tarball. It pointed @openzeppelin/=lib/openzeppelin-contracts/, a Foundry-only path that doesn't exist inside the npm package. Hardhat 3 respects nested remappings.txt from installed packages and failed to resolve OpenZeppelin imports as a result. Foundry consumers who install via git submodule are unaffected; npm/Hardhat consumers now resolve @openzeppelin/contracts through standard node_modules lookup.
