Important Upgrade: Fortuna
Get ready for the **Fortuna** upgrade, bringing key enhancements to the Avalanche network! The most significant update is the implementation of ACP-176. This introduces **Dynamic EVM Gas Limits and Price Discovery Updates** for the C-Chain, aiming to improve the predictability and efficiency of transaction fees.
The Fortuna upgrade will activate on Mainnet at **11 AM ET (3 PM UTC) on Tuesday, April 8th, 2025**. It is **critical** that all Mainnet nodes supporting Fortuna are upgraded to the latest version before this activation time to maintain compatibility and continue participating in the network.
Please note: This release **no longer supports Ubuntu 20.04 (Focal)**. Users running nodes on this operating system must upgrade to a newer version of Ubuntu or another supported OS.
This version also includes valuable additions like ProposerVM block timestamp metrics and a new network health check to alert Mainnet validators that haven't established ingress connections after startup. Alongside these are various performance optimizations, bug fixes, and developer tool improvements.
Ensure your node is running the latest Fortuna-compatible version now!
This upgrade consists of the following Avalanche Community Proposal (ACP): - [ACP-176](https://github.com/avalanche-foundation/ACPs/blob/main/ACPs/176-dynamic-evm-gas-limit-and-price-discovery-updates/README.md) Dynamic EVM Gas Limits and Price Discovery Updates The ACP in this upgrade goes into effect at 11 AM ET (3 PM UTC) on Tuesday, April 8th, 2025 on Mainnet. **All Fortuna supporting Mainnet nodes should upgrade before 11 AM ET, April 8th 2025.** The plugin version is unchanged at `39` and is compatible with version `v1.12.2`. ## Ubuntu Focal Deprecation Because Ubuntu 20.04 is reaching the end of its support window, the binaries attached to this release do not support Ubuntu 20.04 (Focal). ## APIs - Added ProposerVM block timestamp metrics: `avalanche_proposervm_last_accepted_timestamp` - Added network health check to alert if a primary network validator has no ingress connections. Runs a configurable time after startup or 10 minutes by default. ## Configs - Added: - `--proposervm-min-block-duration` - `--network-no-ingress-connections-grace-period` to configure how long after startup it is expected for a Mainnet validator to have received an ingress connection. ## What's Changed -
