June 2025 monthly summary for smartcontractkit/chainlink-ccip: Implemented Aptos gas price calculations in the calculation library to support accurate USD-per-unit gas conversions for the Aptos blockchain, expanding CCIP's multi-chain compatibility. Added Aptos-specific tests to validate the new logic and ensure production-readiness. No major bugs fixed this period; primary focus was feature delivery and test coverage. Prepared the repository for smooth production deployment with enhanced cross-chain pricing capabilities.

Month: 2025-05 — Key feature delivered: ARM64 Architecture Support for the Aptos Blockchain Testing Framework within the chainlink-testing-framework. The change dynamically selects the Docker image based on detected runtime architecture and explicitly sets the image platform, defaulting to an unofficial arm64 image when necessary to maintain compatibility. This broadens hardware coverage for Aptos tests and reduces environment-related failures. Major bugs fixed: None reported. Overall impact and accomplishments: Expanded cross-architecture support, enabling ARM64 CI runners and devices to participate in testing, reducing friction in ARM64 environments, and increasing test coverage for Aptos. Technologies and skills demonstrated: Docker image platform handling, runtime architecture detection, conditional image selection, Aptos testing environment, cross-platform CI considerations.
