filecoin-project/lotus v1.14.0

on GitHub

This is a MANDATORY release of Lotus that introduces Filecoin network v15, codenamed the OhSnap upgrade.

The network is scheduled to upgrade to v15 on March 1st at 2022-03-01T15:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, and worker(s).

The OhSnap upgrade introduces the following FIPs, delivered in actors v7:

• FIP-0019 Snap Deals
• FIP-0028 Remove Datacap from Verified clients

It is recommended that storage providers download the new params before updating their node, miner, and workers. To do so:

• Download Lotus v1.14.0 or later
• run make lotus-shed
• run ./lotus-shed fetch-params with the appropriate proving-params flag
• Upgrade the Lotus daemon and miner when the previous step is complete

All node operators, including storage providers, should be aware that a pre-migration will begin at 2022-03-01T13:30:00Z (150 minutes before the real upgrade). The pre-migration will take between 20 and 50 minutes, depending on hardware specs. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries.
