# v1.22.0 / 2023-04-21
|
||||
|
||||
This is the MANDATORY 1.22.0 release of lotus.
|
||||
This is the stable release of Lotus v1.22.0 for the upcoming MANDATORY network upgrade at `2023-04-27T13:00:00Z`, epoch `2809800`. This release deliver sthe nv19 Lighting and nv20 Thunder network upgrade.
|
||||
|
||||
Diff from previous RCs:
|
||||
- REVERT [Activation bug fix](https://github.com/filecoin-project/builtin-actors/issues/914)
|
||||
- REVERT [FIP 0052](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
|
||||
Note that you must be on a go version higher then Go 1.18.8, but lower then 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
|
||||
|
||||
## v11 Builtin Actor Bundles
|
||||
|
||||
Make sure that your lotus actor bundle matches the v11 actors manifest by running after upgrading:
|
||||
|
||||
```
|
||||

### Dependencies
|
||||
github.com/filecoin-project/go-state-types (v0.11.0-rc1 -> v0.11.1):
|
||||
|
||||
Activation bug fix is reverted to reduce upgrade risk in order to expedite the upgrade. This is in hopes of helping improve recent chain quality degregadation along with other long syncing time related issues. FIP 0052 requires the activation bug fix to maintain security invariants and so must also be reverted.
