Aug 1, 2025August 2025 monthly summary for atopile/atopile: Delivered a set of targeted, business-focused enhancements across build, PCB diffing, tests, UX, and CI/CD. The build system was refactored to model targets as a DAG with explicit dependencies and an --exclude-target option, enabling selective builds and more reliable pipelines. PCB diffing was made robust and legible with layout-agnostic comparisons and inline diffs for --frozen, and excessive diffs are now truncated to reduce noise. Tests were stabilized by updating the inductor pick test to a stocked SMD size, ensuring deterministic results amid component availability changes. UX improvements include clipboard copy support for the embedded package explorer and corrected CLI documentation URL, while LSP graphs gained safeguards against NameError during string-to-enum upgrades. CI/CD and telemetry were enhanced with a Docker KiCad CI environment, Claude AI-assisted code reviews, and attribution telemetry to improve visibility into runs and context. These changes collectively reduce build/test noise, accelerate feedback, and improve developer productivity and product reliability.

Jul 1, 2025July 2025 monthly performance summary for atopile/atopile focused on reliability, developer experience, and CI-robustness. Delivered robust CLI error handling and messaging, improved dependency manifest synchronization and transitive dependency syncing, and strengthened build reliability with automatic dependency installation at build start and enhanced logging. Hardened KiCad build integration with DRCs running in CI and tidier error messages; refreshed per-build library integrity by regenerating fp-lib-table; and improved ecosystem tooling with ATO import-path flexibility and VSCE integration (package explorer and telemetry persistence). These changes reduce failure modes, improve reproducibility, and accelerate safe releases.
