Avalanche Network Upgrades

Avalanche Network Upgrades tracks every scheduled mainnet upgrade on the Avalanche blockchain, a high-throughput, proof-of-stake layer-1 platform. The upgrade schedule is organized by the Avalanche community through Avalanche Community Proposals (ACPs) and is implemented via releases of the AvalancheGo client, the official node software maintained by Ava Labs. Each event entry provides the exact date and time of the activation, the AvalancheGo version required for the upgrade, a list of the ACPs included, and any accompanying network changes such as new precompiles or fee adjustments. The calendar covers upgrades that have occurred since the Apricot phase in 2021 and continues forward, helping validators, developers, and ecosystem participants anticipate when the network will undergo significant protocol changes. The upgrades appear as named releases—such as Apricot Phase 5 (December 2021), Apricot Phase 6 (September 2022), Banff (October 2022), Cortina (April 2023), Durango (March 2024), Etna (December 2024), Fortuna (April 2025), and Granite (November 2025)—each timed to a specific block height or timestamp. Activation occurs on the Avalanche mainnet at a precise moment that is converted to the viewer’s local time zone within the calendar, ensuring accurate scheduling across all regions. The calendar does not include testnet or Fuji testnet upgrades, focusing solely on the production mainnet. Node operators and validators rely on these upgrade windows to update their AvalancheGo software ahead of the hard fork deadlines. The cadence of upgrades is irregular, driven by development milestones rather than a fixed calendar cycle; typically, one to two upgrades happen per year, often clustering in the spring and winter months. For those who operate Avalanche validators, manage DeFi protocols, develop dApps, or trade on the network, missing an upgrade activation can result in downtime or exposure to incompatibility. Subscribing to this smart calendar feed—free to subscribe—places each upgrade directly into a personal calendar, whether that is Apple Calendar, Google Calendar, or Outlook. The finance calendar removes the need to manually track announcements across Discord, GitHub, and the Avalanche forum. It will automatically populate the exact activation time and details, allowing a team or individual to plan maintenance, client updates, and monitoring around the event. The feed is maintained by automated monitoring of Avalanche’s official release channels, ensuring the data reflects the latest confirmed schedules. The calendar updates regularly, pulling from official sources such as the Avalanche GitHub repository and developer blog. Should an activation time be rescheduled or a new upgrade announced with little notice, the calendar feed reflects the change promptly, so subscribers see the corrected information without manual re-entry.
