@@ -4,6 +4,42 @@ All notable changes to `pdf-tools` are documented here.
The project follows a pragmatic versioning scheme while the app is still below `1.0.0`: minor versions mark coherent user-facing milestones; patch versions mark fixes and small improvements.
## 0.3.0 — Selection workspace and maintenance release
### Added
- Added “Open selection as workspace” to create a new unsaved active workspace from the selected pages in current visual order.
- Added selection-workspace helper tests for visual-order selection and derived naming.
- Added TypeScript type-check, ESLint, Prettier, and aggregate `check` scripts.
- Added ESLint flat config with TypeScript, React Hooks, React Refresh, browser, and Node config support.
- Added Prettier configuration and ignore file.
- Added Vite client type declarations for worker URL imports.
- Added Vitest-based test scripts for one-off and watch-mode test runs.
- Added pure tests for workspace command cloning, snapshot command stability, and serializable command record round-tripping.
- Added hook-level tests for workspace load/replace behavior, command execution, undo, redo, history, redo clearing, dirty-state updates, and content-change callbacks.
### Changed
- Bumped the app/package version to `0.3.0`.
- Switched to `@vitejs/plugin-react`.
- Marked the package as an ES module package to remove the Vite CJS Node API deprecation warning during local tooling runs.
- Ran Prettier across the project after adding the formatting configuration.
- Split the former monolithic `ReorderPanel` into focused page-workspace components: `PageGrid`, `PageCard`, `PageSelectionToolbar`, `DropIndicator`, and `CopyPagesDialog`.
- Kept drag/drop move, Ctrl/⌘ copy-drag, selection, rotation, deletion, preview opening, and copy-by-position behavior wired through the existing `ReorderPanel` API.
- Extracted generated PDF download URL creation and cleanup for split, extract, and export results into `src/hooks/usePdfGeneratedOutputs.ts`.
- Updated `ActionsPanel` to render prepared download objects instead of creating object URLs during render.
- Extracted workspace page, selection, dirty-state, message, undo/redo history, command creation, command execution, and reset/load helpers from `App.tsx` into `src/workspace/useWorkspaceState.ts`.
- Extracted thumbnail state, caching, invalidation, progressive rendering, rotation-aware rendering, copied-page thumbnail reuse, and thumbnail error reporting into `src/pdf/usePdfThumbnails.ts`.
- Kept PDF loading, IndexedDB persistence, dialogs, preview, merge, export, and split orchestration in `App.tsx` for now.
### Fixed
- Renamed Prettier config files to `.prettierrc.json` and `.prettierignore` so Prettier picks them up automatically.
- Fixed existing `tsc --noEmit` failures for Vite worker URL imports and `Uint8Array`/`BlobPart` PDF byte handling.
- Removed a duplicate copy-dialog validation error assignment in `ReorderPanel`.
- Rotated thumbnails from loaded/saved workspaces are now regenerated from the actual current page rotation instead of relying only on rotation changes after load.
- Copied/duplicated pages now receive thumbnails through the shared thumbnail hook/cache path instead of ad-hoc copy handling in `App.tsx`.

v0.2.0 — Browser-only PDF workspace baseline

This release preserves the browser-only workspace baseline and adds the first post-refactor feature: opening selected pages as a new active workspace. Workspace state, thumbnail handling, generated download URLs, page-grid components, tests, type-checking, linting, and formatting are separated enough to support additional feature work without turning `App.tsx` back into a monolith.
