What's New
Major release unifies six editors into one SDK with new Server and AI SDKs.
Breaking Changes
- Browser requirements updated to Chrome/Edge 88+, Firefox 90+, Safari 14.1+, and Electron 12
- Presets no longer ship UMD builds; applications must use module-based builds
- Renamed Facade APIs (e.g., createUniverSheet -> createWorkbook)
- Removed Product-specific Exchange APIs; requires migration to new import methods
- Removed Uniscript and custom code execution paths
New Features
- New PDF viewer and editor with page management and annotations
- New structured data workspace (Bases) with grid, kanban, calendar, and Gantt views
- New canvas for diagrams and mind maps (Boards) with Mermaid import
- New chart types including histograms, treemaps, sunburst, and gauge charts
- Mobile editing support for touch-oriented interfaces
Improvements
- Performance improvements including incremental scrolling and progressive layout
- New Server SDK for backend integration and AI SDK for agent workflows
- Embedding capabilities allowing editable documents within other documents
- Reorganized formula engine with 3D and cross-workbook references
- Improved sections and pagination, tables of contents, footnotes, content controls, LaTeX, and calculated inline formulas
Upgrade Notes
Update your build configuration to use module-based builds as UMD is removed. Update your code to use renamed Facade APIs like `createWorkbook` instead of `createUniverSheet`. Ensure your browser environment meets the new minimum version requirements (Chrome 88+, etc.).
