 |---|---|---|
+| 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 |
+| 2026-10-21 | minor | Paste Special laid out as Excel's: Paste and Operation options each in two columns inside a frame, Skip blanks and Transpose side by side, Paste Link as a button that pastes references at once; labels translated (the generic form didn't translate them) and the window no longer runs past the screen |
+| 2026-10-21 | minor | Form dialogs (conditional-format quick rules, New Name, Remove Duplicates, Text to Columns and every other `Dialog::form`) fit their content: OK and Cancel sit in a row under the last field instead of a right-to-left layout that took the screen's whole height and left the buttons floating halfway down |
+| 2026-10-20 | minor | Esc and Enter close a message over the cell editor, such as a data validation alert, and the entry stays open to fix, with the keyboard back in it. Before, the editor took them (the first Esc cancelled the edit behind the alert and only the second closed it), and after the message typing went nowhere until the cell was clicked |
 | 2026-10-21 | minor | Ribbon catalog count 274 / 290 → 275 / 291 (View › Macros › Record Macro) |
 | 2026-10-19 | minor | Ctrl+Enter (`range.fill`) gives each cell what typing the input there gives: a General cell gets the automatic number format (`5%`, `$5`, `3/4/2026`, `=TODAY()`) even when it already held a value, and a cell with its own format, a formatted row or column, or Text keeps it. Cells that held a value used to keep General (`5%` showed 0.05), and empty cells took the active cell's format |
+| 2026-10-19 | trivial | While a mouse button is held (a click or a drag selecting cells) the selection outline is drawn on its cells at once instead of gliding after the pointer, which read as lag; keyboard moves still glide |
 | 2026-10-18 | minor | Keytip letters typed with left Alt held continue the sequence (Alt+H, O, A / Alt+H, O, I ran nothing before: Alt+letter cancelled keytips); other Alt combinations, AltGr and macOS Option are unchanged (#1846) |
-| 2026-10-12 | minor | The File view's recent list tells when each workbook was last changed, read off the UI thread |
+| 2026-10-17 | minor | A Ctrl+Alt+letter key that types a character (a user-defined Windows hotkey such as Ctrl+Alt+A for `ä`) types it instead of running the Ctrl+letter shortcut, e.g. Select All (#1530) |
+| 2026-10-16 | minor | Right-drag on the fill handle opens the fill menu on release: Copy Cells, Fill Series, Fill Formatting Only, Fill Without Formatting, Series…; Esc cancels the drag or closes the menu without filling |
+| 2026-10-16 | minor | With the active cell in a Table whose header row is scrolled out of view, the column headings show the header names and their filter buttons in place of the letters (#1423) |
+| 2026-10-16 | minor | Ctrl+6 hides every object (charts, pictures, shapes, slicers) and shows them again; hidden objects are not drawn, take no clicks and drop their selection, and the setting is saved with the workbook (`workbookPr showObjects`) |
+| 2026-10-16 | minor | Ctrl+Shift+A (Control+Shift+A on a Mac) after a function name, or after its `(`, inserts the argument names and the closing parenthesis, as in Excel; one Undo in the editor takes them back |
+| 2026-10-16 | minor | Advanced Filter ribbon dialog, optional criteria for unique-only extraction (#1622); safe copy-to output (#1031) |
+| 2026-10-16 | minor | Remove Duplicates shows an editable Range field initialized from the selection and passes it to the engine on OK (#1388). Live range-picking outside the dialog remains unsupported |
+| 2026-10-16 | minor | Web printing registers one-shot `afterprint` cleanup before opening the dialog; missing content windows and setup, listener or print failures also release the hidden iframe and PDF blob URL (#1054) |
+| 2026-10-16 | minor | The shared UI clock delegates to the core Unix-millisecond clock, which reads Date.now() on wasm, instead of returning zero there (#1026). Native clock contract tested; browser timing remains unverified |
+| 2026-10-16 | trivial | Web: preferences (theme, interface size, language, editing options…) are kept in the browser's `localStorage` between visits, as the desktop app keeps `ui.json` and `prefs.json`; before, a reload brought back light mode and the defaults (#1562) |
+| 2026-10-15 | minor | Number-format named colors use their RGB values; indexed `[Color1]`–`[Color56]` resolve through the shared legacy palette in grid and PDF (#1452) |
+| 2026-10-14 | minor | Spill-child formula bar uses the anchor formula with disabled theme text and blocks formula-bar edit entry; selection and recalculation restore ordinary behavior |
+| 2026-10-14 | minor | PivotTable source-field list fills the pane width so its scrollbar stays at the list's right edge |
+| 2026-10-13 | minor | Dragging a sheet tab with Ctrl held (Cmd or Option on macOS) drops a copy of the sheet where the tab is released, with the copy cursor (#971) |
+| 2026-10-13 | trivial | More Colors… and Recent Colors (#928) |
+| 2026-10-13 | minor | Grid drags keep their own cursor over selection borders, fill handles and outside the grid; hover resumes on release (#936) |
+| 2026-10-13 | minor | AutoFill month patterns retain the workbook's date system, preventing shifted dates in 1904 workbooks when filling forward or backward |
+| 2026-10-13 | minor | Sheet tab bar: the tab strip shrinks to its tabs, up to 60% of the bar, so New sheet (+) sits right after the last tab and the horizontal scrollbar takes the rest (part of #943) |
 | 2026-10-13 | minor | Horizontal scrollbar in the sheet tab bar: drag, track click pages, frozen columns excluded from the page (#840) |
+| 2026-10-13 | minor | Formula-entry Command/Ctrl-click adds arguments and Shift-click extends references; ordinary replacement and dragging retain their behavior. Readiness estimates unchanged. |
+| 2026-10-12 | minor | Next/previous sheet navigation no longer activates hidden worksheets at either workbook boundary; command tests cover Hidden, VeryHidden and selection retention |

 | 2026-10-12 | minor | Ctrl+wheel zoom steps along a ladder of percentages about 20% apart that never skips 100%, gliding to each step with animations on, so a notch out undoes a notch in (it drifted: 100 → 122 → 101); Excel steps 15 points, see decisions.md |
