Pre-release v2.0.0-rc.1
This is a required upgrade for all nodes on the Prater Testnet.
As you may have heard, Prater is upgrading to Altair at 2021-09-02 12:24:00 UTC. We are recommending a pre-release for Prater hard fork to ensure bugs and breakages do not leak into mainnet. Please DO NOT upgrade for your mainnet nodes with this release. We will have a proper release for that after stability has been ensured in the testnet.
Thank you all for the support!

Prater Genesis Bootstrapping
If you have not run a Prater Prysm node yet, you will need to download the pre-generated genesis state for prater and provide the beacon node flag --genesis-state=/path/to/prater/genesis.ssz.
The genesis.ssz state file can be found in the eth2-clients/eth2-networks repo.
