This release, v1.27.1, is an OPTIONAL lotus release. It is HIGHLY RECOMMENDED for node operators that are building Filecoin index off lotus!

☢️ Upgrade Warnings ☢️

  • This Lotus release completely removes the Legacy Lotus/Lotus-Miner Markets sub-system from the codebase, which was announced to reach EOL on January 31, 2023.
  • The Curio Storage software, designed to simplify the setup and operation of storage providers, has moved to their own Github-repository: https://github.com/filecoin-project/curio.
  • The events subsystem includes some minor correctness fixes and performance improvements. Nodes operators running Lotus with events turned on (off by default) may experience some delay in initial start-up as a minor database migration takes place and the write-ahead log is compacted. See filecoin-project/lotus#11952 and filecoin-project/lotus#12090 for full details.
    • As the events database migration is relatively straightforward in this upgrade, it may be possible to undo the migration for users needing to downgrade specifically from v1.27.1 to v1.27.0, although you are advised to have backups of your Lotus repo before attempting this. Details can be found at: #12073 (comment)

JSON-RPC 2.0 Specification Conformance

The JSON-RPC 2.0 specification requires that a "result" property be present in the case of no error from an API call. This release ensures that all API calls that return a result have a "result" property in the response. This is a behaviour change over Lotus v1.26 and will impact any API call that only has a single error return value, where no error has occurred.

For example, a successful WalletSetDefault in v1.26 would return: 

{
  "jsonrpc": "2.0",
  "id": 1
}

As of this change, in conformance with the JSON-RPC 2.0 specification it will return: 

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": null
}

There is no change in the behaviour when a call returns an error, as the error object will still be present in the response.
