ReleasePort's take
Light signalLibraries v0.64.0 introduces several validation features and bug‑fix rewrites for workbook objects while modestly improving core performance.
Why it matters: Adds plan data, runtime requirements, command request, and receipt validation for workbooks; rewrites cross‑sheet conditional formats, sparklines, and error handling – all boosting reliability. Core scalar dependency allocations drop by ~20 %.
