v1.26.0-rc3

This is the third release candidate of the upcoming MANDATORY Lotus v1.26.0 release, which will deliver the Filecoin network version 22, codenamed Dragon 🐉. This third release candidate brings in multiple storage provider fixes, and cleanups for issues encountered during testing in the Calibration network.

This release candidate only has the calibration network to upgrade set, which happened at epoch 1427974, 2024-03-11T14:00:00Z. This release does NOT set the mainnet upgrade epoch, which will be updated in the final release.

The Filecoin network version 22 delivers the following FIPs:

• FIP-0063: Switching to new Drand mainnet network
• FIP-0074: Remove cron-based automatic deal settlement
• FIP-0076: Direct data onboarding
• FIP-0083: Add built-in Actor events in the Verified Registry, Miner and Market Actors

v13 Builtin Actor Bundle

The actor bundles for the calibration network can be checked as follows:

Migration

We are expecting a bit heavier than normal state migration for this upgrade due to the amount of state changes introduced with Direct Data Onboarding.

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the upgrade. It will take around 10-20 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

You can test out the migration by running running the benchmarking a network migration tutorial.
