Full Changelog: v0.4.0...v0.5.0

Breaking Changes

• The addresses object returned by the artifacts server no longer contains the mockHyperdrive field. Instead, the address of the pool that uses the ERC4626Hyperdrive instance (this is configured to represent an sDAI market) is in the erc4626Hyperdrive field, and the address of the pool that uses the StETHHyperdrive instance (this is configured to represent a stETH market) is in the stethHyperdrive field.
• A new field was added to getPoolInfo called zombieBaseProceeds: https://github.com/delvtech/hyperdrive/blob/10691c2a9a9d60566bcf12850d533acf5ef85df5/contracts/src/interfaces/IHyperdrive.sol#L214. This field allows us to easily calculate the zombie interest that has accrued since the last collection.
• Zombie positions are now discounted to account for negative interest that has accrued. This negative interest is socialized, so it's possible for a zombie to receive a negative interest haircut even if the negative interest accrued before the position matured.

Features

• A StETHHyperdrive instance was added. If asBase = true, the deposit is accepted in native ETH. If asBase = false, the deposit is accepted in stETH shares (note that this is not denominated in stETH tokens).
