# ETHplus Upgrade to Release 4.2.0 and Removal of Legacy Onchain State
[https://forum.reserve.org/t/ip-ethplus-upgrade-to-release-4-2-0-and-removal-of-legacy-onchain-state/1452](https://forum.reserve.org/t/ip-ethplus-upgrade-to-release-4-2-0-and-removal-of-legacy-onchain-state/1452)
This proposal recommends upgrading ETHplus to Reserve Protocol v4.2.0 to align it with the latest supported smart contract release. The upgrade consists of a single onchain spell that upgrades core contract implementation contracts and rotates governance and collateral plugins to their v4.2.0 equivalents.
The proposal also aims to remove legacy onchain state. Specifically, obsolete TimelockControllers that still retain pauser and freezer roles will be removed. These controllers were not removed after the v3.4.0 upgrade and represent an unnecessary governance grief vector.
