 ## [Unreleased]
 
+## [0.5.0] - 2026-07-24
+
+### Added
+
+- Added `recognizeDocument()` async generator API to `@arcships/light-ocr` for unified document OCR. Accepts file paths, `Buffer`, or arrays thereof; auto-detects PDF (magic bytes or `.pdf` extension) and delegates to per-page image OCR otherwise. Each yielded page result carries `source.kind`, `appliedTransforms.pdf`, page dimensions, OCR lines, and `timingUs`.
+- Added `light-ocr document` CLI subcommand with flags: `--source <path>`, `--page-range start-end`, `--dpi <n>`, `--format json|text`, `--max-pages <n>`, and `--abort-on-limit`. Processes PDF and multi-page image sources from the command line.
+- Added `hasPdfSupport()` runtime probe to detect `pdfium-native` availability without throwing. Both the CLI and API gracefully degrade when PDF rendering is unavailable.
+- Added `light-ocr doctor --json` system diagnostics command for hardware and runtime information collection (no user content collected).
+- Added bounded PDF resource limits: `maxPages` (default 100), `maxPagePixels` (16 MiB), `maxTotalPixels` (100 MiB), and `maxFileBytes` (100 MiB). Violations surface as `resource_limit_exceeded` `OcrError` before rendering begins.
+- Added `AbortSignal` passthrough to `recognizeDocument()`, `processPdf()`, and `processImages()`, checked between each page to allow cooperative cancellation of long-running document jobs.
+- Added CPU performance baseline benchmark script (`tools/cpu-benchmark.mjs`).
+
+### Changed
+
+- `@arcships/light-ocr` now lists `pdfium-native` as an optional dependency. When the native PDFium binary is not installed, `hasPdfSupport()` returns `false` and `recognizeDocument()` handles PDF sources by throwing a clear `unsupported_capability` error instead of a module-not-found crash.
+- The `light-ocr` CLI now includes `document` and `doctor` alongside `recognize`, `detect`, and `info` in its subcommand surface.
+- Updated pdfium-native API calls to match v0.6.1 (`loadDocument`, `getPage`, `page.width/height`, `render({scale})`).
+- Added `page.close()` to prevent native memory leaks in multi-page PDFs.
+- Exported `loadNative` from runtime for doctor command integration.
+
+### Fixed
+
+- Fixed PDF processing broken by pdfium-native API mismatch.
+
+### Notes
+
+- This is the N3 document entry release (roadmap §N3). The feature adds PDF and multi-page image document processing as a new entry point for the `light-ocr` Small package. PDF rendering is optional; image-only document workflows require no additional native dependency.
