v0.45.15

Cosmos SDK v0.45.15 Release Notes

This release includes the migration to CometBFT v0.34.27.
This migration should be minimally breaking for chains.
From v0.45.15+, the following replace is mandatory in the go.mod of your application:

// use cometbft
replace github.com/tendermint/tendermint => github.com/cometbft/cometbft v0.34.27

Additionally, the SDK sets its minimum version to Go 1.19. This is not because the SDK uses new Go 1.19 functionalities, but to signal that we recommend chains to upgrade to Go 1.19 — Go 1.18 is not supported by the Go Team anymore.
Note, that SDK recommends chains to use the same Go version across all of their network.
We recommend, as well, chains to perform a coordinated upgrade when migrating from Go 1.18 to Go 1.19.

Please see the CHANGELOG for an exhaustive list of changes.

End-of-Life Notice

v0.45.15 is the last release of the v0.45.x line. Per this version, the v0.45.x line reached its end-of-life.
The SDK team maintains the two latest major versions of the SDK. This means no features, improvements or bug fixes will be backported to the v0.45.x line. Per our policy, the v0.45.x line will receive security patches only.

We encourage all chains to upgrade to the latest release of the SDK, or the v0.46.x line.

Refer to the upgrading guide for how to upgrade a chain to the latest release.

FAQ Migration to CometBFT v0.34.27

I use tm-db but I get an import error with cometbft-db

For preventing API breaking changes, the SDK team has kept using tm-db for v0.45.x and v0.46.x.
However, the CometBFT team kept using cometbft-db for their v0.34.x line.
This means if your app directly interact with CometBFT (e.g. for a force pruning command), you will need to use cometbft-db there.
When not interacting with CometBFT directly, you can use tm-db as usual.

I get import errors with btcd

If you are using an old version of btcd, you will need to upgrade to the latest version.
The previous versions had vulnerabilities so the SDK and CometBFT have upgraded to the latest version.
In the latest version btcsuite/btcd and btcsuite/btcd/btcec are two separate go modules.

I encounter state sync issues

Please ensure you have built the binary with the same Go version as the network.
You can easily verify that by querying /cosmos/base/tendermint/v1beta1/node_info of a node in the network, and checking the go_version field.

🚀 Highlights

• Upgrade to CometBFT v0.37.0.

  • With the notable introduction of ABCI 1.0.
  • Changes of events keys and values from []byte to string.

• Support of ABCI 1.0 in the SDK.

  • Allows chains to set their own mempool implementation. Follow the guide here.
  • Support of the new PrepareProposal and ProcessProposal ABCI methods.

• Deprecation of the x/params module.

  • Modules params are now handled directly by the modules themselves, via the MsgUpdateParams message.
  • All core SDK modules have migrated away from using x/params. It is recommended to migrate your custom modules as well.

• Migration from gogo/protobuf to cosmos/gogoproto.

  • The SDK was using the now unmaintained gogo/protobuf library. This has been replaced by cosmos/gogoproto which is a fork of gogo/protobuf with some improvements and fixes, that is maintained by the Cosmos SDK team.
  • This change is not transparent for applications developers. All proto files should be regenerated with the new library.
  • Use the ghcr.io/cosmos/proto-builder image (version >= 0.11.5) for generating protobuf files.

• App Wiring with dependency injection.

  • App Wiring is ready for community feedback. It allows developers to build a chain with less boilerplate by removing the need to manually wire a chain.
  • Community feedback will be implemented in the following releases which can lead to API breakage (runtime and depinject are pre-1.0).
  • Manually wiring an application is still possible and will always remain supported.

• Removal of the proposer-based rewards from x/distribution.

  • This removes unfairness towards smaller validators.

• Re-addition of title and summary fields on group and gov proposals.

  • In v0.46 with x/gov v1, these fields were not present (while present in v1beta1). After community feedback, they have been added in x/gov v1.

• Refactoring of tests in the SDK and addition of the simtestutil package, for facilitating testing without depending on simapp.

  • Any dependencies on simapp in an application must be removed going forward.

v0.46.8

Cosmos SDK v0.46.8 Release Notes

This release introduces bug fixes and improvements. Notably, the SDK have now switched to Informal Systems' Tendermint fork.
Their fork has no changes compared to the upstream Tendermint, but it is now maintained by Informal Systems. Chains are invited to do the same.

Moreover, this release contains a store fix. The changes have been tested against a v0.46.x chain mainnet with no issues. However, there is a low probability of an edge case happening. Hence, it is recommended to do a coordinated upgrade to avoid any issues.

Please see the CHANGELOG for an exhaustive list of changes.
