TechFlow reports, Ava Labs developer relations engineer Usman Asim tweeted: "Reminder to all Avalanche validators: The Cortina AvalancheGo release (v1.10.0) is now available and will activate at 23:00 UTC+8 on April 25. Validators must upgrade their nodes before this date, otherwise they will be unable to process new blocks after the upgrade." GitHub information indicates that the upgrade changes will take effect on the mainnet at 23:00 on April 25.
The Cortina upgrade migrates the X-Chain to run Snowman++ consensus, meaning the entire network has now moved to a single consensus engine. The Cortina upgrade also introduces batched delegation rewards and increases the C-Chain gas limit to 1500 gas.
Previously, Avalanche activated the Cortina upgrade on the Fuji testnet on April 6.
