Forest NV27 support 🏮

[LesnyRumcajs]

NV27 upgrade

Forest joins Lotus and Venus in supporting the NV27 upgrade. See the post for details regarding the new features brought to the network.

To keep Forest nodes running, the operators must upgrade Forest to supporting versions, as outlined in the timeline.

📆 Timeline

timeline
    title NV27 Forest timeline
    September 8th : Forest release supporting NV27 for calibnet
    September 10th : Calibration NV27 network upgrade
    ~September 18th : Forest release supporting NV27 for mainnet
    September 24th : Mainnet NV25 upgrade

Loading

The timeline is subject to changes, and there will likely be non-mandatory releases. Depending on external factors, the Forest release for mainnet will likely arrive faster to give plenty of time for an update.

💻 Hardware requirements

The state migration for this upgrade is minimal. Depending on your hardware, the time to migrate the state will vary.

• calibnet: around 2s,
• mainnet: around 23s with peak RSS 18 GiB.

Tip

To lower the time required for the state migration, you can prune the chain data before the upgrade. This is done by removing the $HOME/.local/share/forest/mainnet on Linux and importing the snapshot before the upgrade.

An alternative to the automatic state migration is downloading a snapshot from the ChainSafe snapshot service sometime after the upgrade (30m - 2h). Endpoints below:
