Fortuna - C-Chain Fee Overhaul

This upgrade consists of the following Avalanche Community Proposal (ACP):

• ACP-176 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.
