Pre-release v2.0.0-rc.0
This is a required upgrade for all nodes on the Pyrmont Testnet.
As you may have heard, Pyrmont is upgrading to Altair at 2021-08-19 12:00:07 UTC. We are recommending a pre-release for Pyrmont hard fork to ensure bugs and breakages do not leak into mainnet. Please DO NOT upgrade for nodes other than Pyrmont testnet. We will have a proper release for that after stability has been ensured in the testnet.
Thank you all for the support!
