Compound.js v0.4.3
This patch updates the cWBTC token address on mainnet to the new contract. The legacy contract has minting paused. Users of Compound.js versions prior to v0.4.3 will experience an error when trying to supply WBTC. Now that the SDK points to the new contract, this error does not occur. If you have supplied to the original cWBTC contract, you will need to redeem your cTokens another way or by using Compound.js v0.4.2 or lower.
