Hi everyone,

The cLabs team is happy to announce **Core Contracts Release 8**!

### Overview

The upgrade includes the following changes described with more detail in the [release notes](https://github.com/celo-org/celo-monorepo/releases/tag/core-contracts.v8.pre-audit):

- Adds `FederatedAttestations.sol`: Similar to `Attestations.sol`, this new contract records mappings from bytes32 identifiers to addresses, and is used primarily to resolve off-chain identities like phone numbers to addresses so that users can more easily send each other payments.
- Adds `OdisPayments.sol`: While the original ODIS rate limit imposed this cost by calculating quota as a function of on-chain transaction history, the new rate limit will impose this cost by requiring direct payments to a smart contract.
- Updates `Escrow.sol`: To allow escrowed payments to be gatekeeped by the ‘trusted’ issuer logic introduced in `FederatedAttestations.sol`
