This Week in Lotus - Week 45 - 2023

📢 Network Version 21 - Watermelon - Update: FIP0070 📢

The Lotus team continued to put the Calibration Network through its paces last week and unfortunately we have uncovered an additional bug in the FIP0070 implementation which aims to bring movable partition functionality to the Filecoin network.

The bug is related to sector expiration tracking 📅. When a sector is moved between deadlines, its expiration date isn’t updating correctly in all cases. This could potentially cause expiration tracking issues, especially if there’s a fault and subsequent recovery of a sector/partition.

Considering the 🍉 Watermelon Mainnet upgrade is just around the corner, the governance team has initiated a decision matrix for FIP0070. This will allow our teams to thoroughly investigate and resolve the issue in addition to providing a clear path forward.

The team is now laser-focused on resolving the issue and gearing up for NV21. Over the next few days, we might need to fine-tune the upgrade timeline, so please ensure you’re subscribed to #fil-network-announcements and #fil-lotus-announcements to stay in the loop! 📢👀

Head to this discussion in the #fil-actors channel if you have any questions or would like to dig into the technical details of the issue.
