Cardano Node 1.35.7

Node 1.35.7 is a bug fix release that addresses an issue with the legacy network stack connecting to a P2P relay. SPOs are recommended to deploy this version on all their nodes.

IMPORTANT: P2P on mainnet is only intended to be ran on a single relay at this time. Continue to run any other relays with P2P disabled using the legacy topology.

NOTICE Minimum resources were adjusted in this release due to chain growth.

Please note that this version contains no breaking changes
