ReleasePort's take

Light signal

editorial:auto 14d

libraries-v0.40.31 improves performance for headless numeric undo batches and excel-import calcchain processing. Excel-import module refactoring enhances code organization.

Why it matters: Routine maintenance release with incremental performance gains. No breaking changes; test in dev if headless or excel-import is performance-critical.
