## [0.4.0] - 2026-03-07

### Added
- **VaultCache** (`src-tauri/src/cache.rs`): In-memory note cache with mtime-based invalidation
- **`init_vault_cache`**: Eagerly scan all `.md` files and populate cache on startup
- **`get_cache_stats`**: Return cache hits/misses/entry count for diagnostics
- **Cache-backed commands**: `read_note`, `read_note_with_meta`, `build_graph`, `search_vault` now read from cache
- **Frontend LRU cache** (`src/lib/noteCache.ts`): Cache last 20 notes with stale-while-revalidate
- **File watcher** (`notify` crate): Foundation for filesystem change detection and cache invalidation

### Changed

- **Outline / TOC Panel**: Right-side panel showing document headings with click-to-scroll and smooth highlight animation
- **Tabbed Right Panel**: Switch between Outline and Backlinks views in the note editor
- **Note Templates**: `_templates/` folder support; Command Palette lists templates and creates notes with `{{title}}`/`{{date}}` replacement
- **Image Attachments**: Drag-and-drop images onto editor; saves to `vault/attachments/` and inserts markdown image link
- **`list_templates`**: Rust command to scan `_templates/` folder for `.md` template files
