- Save As now defaults the version dropdown to DWG/DXF 2018 (latest) instead of the loaded file's version; the selected version is written as-is (removed the source-version fallback for version-locked data). - Pin acadrust 55a2caa: allocate_handle respects header.handle_seed as a floor, fixing the corruption where opening a file and saving it silently overwrote existing XRECORD/DICTIONARY objects (handle reuse) and AutoCAD refused the result.
