 | 2026-10-21 | Page Setup paper sizes match Japanese Excel: `B4`/`B5`/`B6` are the JIS sizes (ISO B4/B5/B6 stay reachable by name), so a Japanese B5 worksheet prints at 182×257 mm; Japanese Postcard (100×148 mm), Double Postcard (148×200 mm), Envelope #3/#4 (120×235/90×205 mm), Kaku #2/#3 (240×332/216×277 mm) and A6 are added, both sizes reach the PDF page (`file.exportPdf`/`file.print` MediaBox) and the size survives an XLSX round-trip; the Page Layout Size menu lists them. `B4`/`B5` used to be the ISO sizes, which is changed here |

+| 2026-10-22 | minor | New workbook no longer loses the first one: the cell being typed is entered into its own workbook before any File or window command (an entry the workbook refuses stays open and the command doesn't run; an untouched F2 draft changes nothing), the editor is tied to its workbook, View › Switch Windows and the macOS Window menu list the open workbooks, and the macOS Quit item asks about unsaved workbooks like the close button |
 | 2026-10-21 | minor | Background error checking, first part (#1994): a constant whose text would be a number if typed (signs, thousands, currency, percent, exponent, parenthesised negative) gets Excel's green corner triangle; the active cell then shows a warning button whose menu names the problem and offers Convert to Number for the selection (`formulas.convertToNumber`). Dates, times and fractions kept as text and formula results are not flagged, as in Excel |
