v4.0.0-rc2

Fix lints (#2628)

v4.0.0-rc1

Upgrade Notes

For Testnet network users the network has been rolled back to block 1,150,000. This release requires either a reindex, restarting from snapshot or a clean sync. The expected hash on block 1,150,000 is 2f0b131e15bdb6e5ecbd0e8fd4f9db798db59aa3c78a3b352594b8db341e1f33.

For Changi network users upgrading from any release before beta15, this release requires either a reindex, restarting from snapshot or a clean sync due to changes in the EVM state. Failure to do this may result in an inconsistent EVM state.

Summary

Note: This is a release candidate pre-release. This is NOT meant for use on production systems.

• Version: 4.0.0-rc1

Testnet EVM

• EVM RPC Port: 18551
