v1.22.1 / 2023-04-23

Important Notice

This is a MANDATORY hotfix release that fixes a consensus-critical bug that was in v1.22.0 -- the necessary fix is filecoin-project/ref-fvm#1750 and it is integrated into lotus via #10735.
You can NOT use 1.22.0 for the nv19 upgrade, you MUST be on 1.22.1 or higher.

About This Release

This is the stable release of Lotus v1.22.1 for the upcoming MANDATORY network upgrade at 2023-04-27T13:00:00Z, epoch 2809800. This release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet.

Note that you must be on a go version higher than Go 1.18.8, but lower than Go v1.20.0. We would recommend Go 1.19.7.

The Lighting and Thunder upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors v11.0.0):

• FIP 0060 - Thirty day market deal maintenance interval
• FIP 0061 - WindowPoSt grindability fix
• FIP 0062 - Fallback method handler for multisig actor

Expedited nv19 Lightning ⚡️ rollout

In light of the recent degraded chain quality on the mainnet an expedited nv19 upgrade has been proposed and accepted to roll out the market cron mitigation (FIP0060) that will improve block validation times, and with that the delay in block production that is causing a decrease in the chain quality currently.

With this expedited roll out we want to inform you of some key changes and important dates:

• Accelerate the nv19-upgrade on mainnet from May 11th to April 27th.
• Derisk nv19 by descoping the sector info migration, activation epoch fixes and drop [FIP0052 - Extend sector/deal max duration to 3.5 year.](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
  • By descoping these changes we can greatly derisk the network upgrade itself by removing a heavy migration that could cause instability for storage providers and node operators during the network upgrade.
• Increase the rollover period for [FIP0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md) from 1 week to 3 weeks on mainnet. The rollover period is the duration between nv19 and nv20 which both old proofs (v1) and the new proofs (v1_1) proofs will be accepted by the network.

The Lighting and Thunder upgrade now implements the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors v11.0.0):

• FIP 0060 - Thirty day market deal maintenance interval
• FIP 0061 - WindowPoSt grindability fix
• FIP 0062 - Fallback method handler for multisig actor
