Jan 1, 2025January 2025: Delivered two focused enhancements in axelar-amplifier that improve release reliability and interchain configuration awareness. Key features delivered include: 1) CI Release Artifact Naming Standardization: standardized release artifact naming to snake_case in CI and updated logic for copying and signing WASM artifacts to replace hyphens with underscores. This reduced naming inconsistencies and streamlined downstream automation. Commit: b77c28148e52dc24db45be5c7199f4a48017bfab. 2) ITS API: Return richer chain configuration in contract address query: extended ITS contract address query to return comprehensive chain configuration information (ITS edge contract addresses, truncation configurations, and frozen status) and updated query name and error types. Commit: 5c8b7812951990fe58b5171d592d0ada98ef203b. Major bugs fixed: addressed CI naming inconsistency bug by enforcing default snake_case naming for cosmwasm releases. Overall impact: improved release reliability, tighter integration between components, and richer run-time data for decision-making; enabled faster incident response and more deterministic deployment pipelines. Technologies/skills demonstrated: CI/CD automation, artifact signing and verification, naming conventions, API design and extension (ITS), release engineering, and cross-component coordination in a Cosmos/CosmWasm-oriented stack.
