ReleasePort's take
Light signalLibraries v0.84.0 introduces multiple new constraints and validations for workbook components, including freezing runtime requirements, agent descriptions, proof verdicts, handoff validators, run results, planning results, helper namespaces, canonicalizing formula readback proofs, validating transported row selectors, and requiring strict command proof.
Why it matters: These feature changes affect all workbook-related operations; developers and SREs must review the new constraints before upgrading to ensure existing workbooks remain compatible after freezing runtime requirements and enforcing stricter validation rules.
Summary
AI summaryLibraries v0.84.0 updates workbook, headless, xlsx modules and upgrades internal runtime packages to v0.84.0.
