|---|---|---|
| 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 |
| 2026-10-18 | 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) |
| 2026-10-16 | 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 |
| 2026-10-12 | minor | Next/previous sheet navigation no longer activates hidden worksheets at either workbook boundary; command tests cover Hidden, VeryHidden and selection retention |
| 2026-10-13 | 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) |
