# v1.22.1 / 2023-04-23
|
||||
|
||||
This is a MANDATORY hotfix release that fixes a consensus-critical bug -- the necessary fix is https://github.com/filecoin-project/ref-fvm/pull/1750
|
||||
## Important Notice
|
||||
|
||||
This is a MANDATORY hotfix release that fixes a consensus-critical bug that was in v1.22.0 -- the necessary fix is https://github.com/filecoin-project/ref-fvm/pull/1750 and it is integrated into lotus via https://github.com/filecoin-project/lotus/pull/10735.
|
||||
You can NOT use 1.22.0 for the nv19 upgrade, you MUST be on 1.22.1 or higher.
|
||||
|
||||
The only change is updating the FVM crates used via the FFI: https://github.com/filecoin-project/lotus/pull/10735.
|
||||
## 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](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0-rc2)):
|
||||
|
||||
- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
|
||||
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
|
||||
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - 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](https://github.com/filecoin-project/core-devs/discussions/123#discussioncomment-5642909) to roll out the market cron mitigation ([FIP0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md)) 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)](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)](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](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0)):
|
||||
|
||||
- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
|
||||
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
|
||||
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - Fallback method handler for multisig actor
|

|
||||
This is the third release candidate for the upcoming MANDATORY 1.22.0 release of Lotus. This release will deliver the nv19 Lighting and nv20 Thunder network upgrade.
|
||||
|
||||
Note that this release candidate sets the calibration upgrade epoch, and does NOT set the epoch at which mainnet will upgrade; that detail will be finalized in the 1.22.0 release.
|
||||
|
||||
The Lighting and Thunder upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors [v11.0.0-rc.1](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0-rc1)):
|
||||
|

|
||||

|
||||
- [FIP 0052](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md) - Deals and sectors can be created and extended in 3.5 year intervals (+2 years from current params)
|
||||
- [Activation bug fix](https://github.com/filecoin-project/builtin-actors/issues/914) - internal refactor of sector info fields fixing several outstanding bugs
|
||||
|
||||
## Lighting and Thunder
|
||||
|
||||
As you may have noticed, that we are doing a two-stage incremental network upgrades in this release. This essentially means that there will be two network versions rolled out together -- nv19 and nv20.
|
||||
The two stage roll out is required for FIP-0061 - which introduces a new proof that reduces the grindability of windowPoSt and furthur secures the network. At the first upgrade, the new proof type will start to be accepted by the protocol, while the second upgrade (nv20) marks the spot when the old proof type will no longer be accepted. This allows for a smooth rollover period during which both proof types are accepted. Lotus will start generating the new proof types immediately after the nv19 upgrade.
|
||||
This is something we've safely done before. The second upgrade is something of a "ghost" upgrade -- no migration runs, and no code changes, except that clients will start reporting the new network version of nv20 to the FVM.
|
||||
|
||||
## Calibration nv19 Lighting and nv20 Thunder Upgrade
|
||||
|
||||
This release candidate sets the calibration-net nv19 Lighting upgrade at epoch 489394, 2023-04-20T16:30:00Z and nv20 Thunder upgrade will be triggered automatically 11520 epoch later. The bundle the network will be using is [v10.0.0 actors](https://github.com/filecoin-project/builtin-actors/releases/tag/v10.0.0-rc.1)
