Walkthrough

Walkthrough

The Cosmos SDK has been updated with new features, improvements, and bug fixes. Notably, it now supports running gRPC and API servers independently, enhancing flexibility in deployment scenarios. Performance is improved through a streaming JSON parser for chain-id extraction from the genesis file. The update also addresses a bug ensuring block size constraints are properly enforced during proposal preparation. However, it introduces client-breaking changes by removing telemetry metrics for vote and proposal counts.

Mistake in the changelog de-duplication. All good now.

CHANGELOG.md (6)

• 43-43: The addition of a key_rotation_fee parameter is a significant feature that could impact the economics of key management within the staking module. Ensure that the implications of this change are well-documented and communicated to stakeholders.

• 53-58: These improvements seem to focus on enhancing the developer experience and performance. The addition of AmountOfNoValidation and the simplification of keyring interfaces are particularly noteworthy as they can reduce the potential for errors and streamline interactions with the SDK.

• 61-65: The replacement of ctx.VoteInfos with ctx.CometInfo should be carefully checked for compatibility issues across the codebase. Also, the change in crypto | x/auth to include key checks on signatures should be reviewed to ensure it doesn't introduce any security vulnerabilities.

• 248-248: Using a streaming JSON parser for parsing the chain-id is a significant improvement in terms of performance, especially for large genesis files. This change should be highlighted as it can have a positive impact on node startup times.

• 546-570: The summary of changes for version 0.47.6 is comprehensive, covering new features, improvements, bug fixes, and client breaking changes. The removal of telemetry for votes and proposals is a breaking change that should be clearly communicated to clients to prepare for alternative solutions.

• 569-569: The removal of telemetry for votes and proposals is a client breaking change that requires clients to adapt their monitoring setups. It's crucial to provide clear migration paths or alternatives for affected users to transition smoothly.

The bug fix in the DefaultProposalHandler is critical for maintaining the integrity of the consensus process. It's important to ensure that this change has been thoroughly tested, especially since it involves transaction selection and block size constraints.
