## [0.7.1] — 2026-03-19
11
+
12
+
### Fixed
13
+
- **Double-line cell borders**: reverted `border-separate` to `border-collapse` with `background-clip: padding-box` — colored cells now keep visible borders without the black+white double-line artifact
14
+
15
+
### Added
16
+
- **Cell editor polish**: teal border + shadow when editing, editor expands beyond cell width, placeholder text ("Type or = for formula")
17
+
- **Row auto-fit**: double-click row resize handle to auto-fit height based on wrapped text content
18
+
- **Header cursors**: column headers show s-resize cursor, row headers show e-resize cursor to indicate click-to-select
19
+
20
+
### Tests
21
+
- 3019 unit tests across 101 test files (+9 from v0.7.0)

- CSS/accessibility improvements for toolbar (#165)
201
+
- Sheets UX iteration 2: performance, polish, and visual testing (#164)
187
202
- **Full TypeScript migration**: all 122 source + test files, zero `any` types
188
203
- **Server reorganized**: `server.js` → `server/index.ts` with full Express/WS/SQLite types
189
204
- **`server.js` shim**: backwards-compatible entry point for Nomad deployment
