github filecoin-project/lotus v1.25.0-rc2

pre-release12 months ago

This is the second 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.

This optional feature release candidate does NOT set an upgrade epoch for mainnet. However, it includes a patch for the calibration testnet to fix an issue where partitions with expired sectors had to be compacted before they could be moved. Unfortunately, this bug impacts consensus and necessitates a coordinated upgrade on the Calibration network to deploy the new code. The calibration network is scheduled to upgrade all miner actors to the new, fixed miner actor CID at epoch 1070494, which is expected to occur at 2023-11-07T13:00:00Z.

Make sure to check out the release log for Lotus v1.24.0-rc3 to see the FIPs delivered in the network version 21 upgrade, v12 Builtin Actor Bundles, features and improvements.

⭐️ 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.
