The release adds execution of transported plan data and persists run proofs in workbooks while fixing several XLSX handling bugs.

Why it matters: These feature additions enable new workflow capabilities, and the bugfixes preserve query table topology and Power Query artifacts when processing XLSX files; all changes land with runtime packages updated to version 0.86.0.
