Overview

This release introduces Multicall3. Multicall3 aggregates results from multiple contract calls.

It contains the following improvements over prior multicall contracts:

• Cheaper to use: fit more calls into a single request before hitting the RPC's eth_call gas limit
• Backwards compatible: it can be dropped in to existing code by simply changing the address
• Uses the same, memorable deployment address on all networks

The major changes to the previous Multicall and Multicall2 are the introduction of the aggregate3 and aggregate3Value functions that allow for failure requirements at the call level. So for a set of calls, each call indicates whether it allows the call to fail. This greatly improves multicalling flexibility.
