Cortina - DAG Linearization - Fuji Pre-Release

Please note that this release is unable to run mainnet - and will display "mainnet is not supported" if attempted to run with a mainnet configuration.

This upgrade linearizes the X-chain, introduces delegation batching to the P-chain, and increases the maximum block size on the C-chain.

The changes in the upgrade go into effect at 11 AM EDT, April 6th 2023 on the Fuji testnet. After Fuji is updated and verified, a mainnet compatible release will be published.

All Fuji nodes should upgrade before 11 AM EDT, April 6th 2023.

The supported plugin version is 25.
