This is the fifth release candidate of the upcoming OPTIONAL release Lotus v1.25.0. This optional release also supports the Filecoin network version 21 upgrade, codenamed Watermelon 🍉, in addition to the numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

❗ Mainnet Upgrade Date Update

Mainnet upgrade date has been adjusted due to the rescope of nv21 & retesting on test network, as well as giving the community enough time to upgrade their infrastructure.

The new date and epoch for the Mainnet nv21 upgrade has therefore been set to epoch 3469380 - 2023-12-12T13:30:00Z.

FIP0070 descoped for nv21

FIP0070: Allow SPs to move partitions between deadlines was originally scoped for network version 21. However, during the testing on calibrationnet testing, this FIP has proven to be quite error prune to implement due to the complexity of the protocol and a couple bugs were discovered.

As the path to resolving this bug is not yet clear, core devs have decided to descope FIP-0070 from the upcoming nv21 upgrade ensure the security and stability of the network post upgrade.

Calibration WatermelonFix2

For the calibration network, the descoping of FIP0070 means that we will need to do another CodeCID migration to drop FIP0070 from nv21, and to get the test network into a state which will be similar to when the mainnet upgrades to nv21.

This migration will happen at epoch 1108174 - 2023-11-21T13:00:00Z.

Make sure to upgrade you calibration network nodes and storage providers to v1.24.0-rcx & ^ before this epoch.

☢️ Upgrade Warnings ☢️

  • Please remove and clone a new Lotus repo (git clone https://github.com/filecoin-project/lotus.git) when upgrading to this version.
  • This feature release requires a minimum Go version of v1.20.7 or higher to successfully build Lotus. Go version 1.21.x is not supported yet.
  • EthRPC providers, please check out the new tracing API to Lotus RPC

⭐️ Highlights ⭐️

Unsealing bugfixes and enhancements

This feature release introduces significant improvements and bugfixes with regards to unsealing, and ensures that unsealing operates as one would expect. Consequently, unsealing of all sector types (deal sectors, snap-sectors without sector keys, and snap-sectors with sector keys) now all function seamlessly.

Some additional unsealing improvements are:

  • Unsealing on workers with only sealing paths works. 🎉
  • Transferring unsealed files to long-term storage upon successful unsealing. ➡️
  • Ensuring no residual files in sealing paths post a successful unsealing operation. 🧹

SupraSeal C2

Lotus-workers can now be built to leverage the SupraSeal C2 sealing optimizations in your sealing pipeline. The code optimizations are currently behind the FFI_USE_CUDA_SUPRASEAL feature flag. We advice users to test this feature on a test-network, before trying to use it on the mainnet. Users can test out the feature by building their lotus-workers by exporting the FFI_USE_CUDA_SUPRASEAL=1 enviroment variable, and building from source. For questions about the SupraSeal C2 sealing optimizations, reach out in the #fil-proofs or the #dsa-sealing slack channel.
