v1.28.0-rc3 Pre-release
Pre-release

This is the third release candidate of the upcoming MANDATORY Lotus v1.28.0 release, which will deliver the Filecoin network version 23, codenamed Waffle 🧇.

This release candidate sets the calibration network to upgrade at epoch 1779094, corresponding to 2024-07-11T12:00:00Z. This release does NOT set the mainnet upgrade epoch yet, in which will be updated in the final release.

Compared to Lotus v1.28.0-rc2, the Lotus v1.28.0-rc3 introduces the manifest for the "control" nodes for F3 passive testing. This change shouldn't have any impact on production nodes.

☢️ Upgrade Warnings ☢️

If you are running the v1.26.0 or an earlier version of Lotus, please go through the Upgrade Warnings section for the v1.27.* releases, before upgrading to this RC.

  • This upgrade includes an additional migration to the events database. Node operators running Lotus with events turned on (off by default) may experience some delay in initial start-up of Lotus as a minor database migration takes place. See filecoin-project/lotus#12080 for full details.

The Filecoin network version 23 delivers the following FIPs:

Note that we are only doing a "soft launch"/"passive testing" for F3 (Fast Finality) i.e. FIP-0086 in NV23. Please see this doc for more details.

Migration

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the network upgrade. The migration for the NV23 upgrade is expected to be light with no heavy pre-migrations, here are some expected timings and resource consumption numbers:

  • Pre-Migration is expected to take less then 1 minute
  • The migration is expected to take less then 30 seconds on a node with a NVMe-drive and a newer CPU. For nodes running on slower disks/CPU, it is still expected to take less then 1 minute.

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), we recommend skipping the pre-migration and run the non-cached migration (i.e., just running the migration at the network upgrade epoch), and schedule for some additional downtime. Operators of such nodes can read the How to disable premigration in network upgrade tutorial.

v1.27.1

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.

v1.27.0

This is an optional feature release of Lotus. Lotus v1.27.0 includes numerous improvements, bugfixes and enhancements for node operators, RPC- and ETH RPC-providers. This feature release also introduces Curio in a Beta release. Check out the Curio Beta release section for how you can get started with Curio.

☢️ Upgrade Warnings ☢️

  • Event Database: Two sequential migrations will adjust indexes without altering data or columns, ensuring minimal invasiveness when upgrading to this release. However, these migrations may be time-consuming for nodes with extensive event databases.
  • This feature release drops the Raft cluster code experiment from the codebase. This Raft cluster never graduated beyond an experiment, had poor UX (e.g. no way to manage a running cluster, so it didn't provide High Availability), and pulled in a lot of heavy dependencies. We keep the multi-node RPC feature, it is not perfect, but it is useful.

Indexers, RPC- and ETH RPC-providers improvements

This release includes a lot of improvements and fixes for indexers, RPC- and ETH RPC-providers. Specifically these PRs:

⭐️ Curio Beta Release ⭐️

Curio, the next generation of Lotus-Miner, also referred to as MinerV2! This release officially transitions Curio into beta and introduces a suite of powerful features designed to enhance your storage operations.

Highlights

  • Curio as MinerV2: Embrace the revolutionary upgrade from Lotus-Miner to Curio. This transition is not just a rebranding—it's an upgrade to a more robust, scalable, and user-friendly version.
  • High Availability: Curio is designed for high availability. You can run multiple instances of Curio nodes to handle similar type of tasks. The distributed scheduler and greedy worker design will ensure that tasks are completed on time despite most partial outages. You can safely update one of your Curio machines without disrupting the operation of the others.
  • Node Heartbeat: Each Curio node in a cluster must post a heartbeat message every 10 minutes in HarmonyDB updating its status. If a heartbeat is missed, the node is considered lost and all tasks can now be scheduled on remaining nodes.
  • Task Retry: Each task in Curio has a limit on how many times it should be tried before being declared lost. This ensures that Curio does not keep retrying bad tasks indefinitely. This safeguards against lost computation time and storage.
  • Polling: Curio avoids overloading nodes with a polling system. Nodes check for tasks they can handle, prioritizing idle nodes for even workload distribution.
  • Simple Configuration Management: The configuration is stored in the database in the forms of layers. These layers can be stacked on top of each other to create a final configuration. Users can reuse these layers to control the behavior of multiple machines without needing to maintain the configuration of each node. Start the binary with the appropriate flags to connect with YugabyteDB and specify which configuration layers to use to get desired behaviour.

v1.27.0-rc3 Pre-release
Pre-release

This is the third release candidate of the upcoming optional release of Lotus v1.27.0. This feature release includes numerous improvements and enhancements for node operators, RPC- and ETH RPC-providers as well as storage providers. This feature release introduces Curio in Beta release. Check out the Curio Beta release section for how you can get started with Curio.

☢️ Upgrade Warnings ☢️

  • This feature release drops the Raft cluster code experiment from the codebase. This Raft cluster never graduated beyond an experiment, had poor UX (e.g. no way to manage a running cluster, so it didn't provide High Availability), and pulled in a lot of heavy dependencies. We keep the multi-node RPC feature, it is not perfect, but it is useful.
  • Event Database: Two sequential migrations will adjust indexes without altering data or columns, ensuring minimal invasiveness when upgrading to this release. However, these migrations may be time-consuming for nodes with extensive event databases.

Indexers, RPC- and ETH RPC-providers improvements

This release includes a lot of improvements and fixes for indexers, RPC- and ETH RPC-providers. Specifically these PRs:

⭐️ Curio Beta Release ⭐️

Curio, the next generation of Lotus-Miner, also referred to as MinerV2! This release officially transitions Curio into beta and introduces a suite of powerful features designed to enhance your storage operations.

Highlights

  • Curio as MinerV2: Embrace the revolutionary upgrade from Lotus-Miner to Curio. This transition is not just a rebranding—it's an upgrade to a more robust, scalable, and user-friendly version.
  • High Availability: Curio is designed for high availability. You can run multiple instances of Curio nodes to handle similar type of tasks. The distributed scheduler and greedy worker design will ensure that tasks are completed on time despite most partial outages. You can safely update one of your Curio machines without disrupting the operation of the others.
