New Features

PDF Engines

• Watermark: Added POST /forms/pdfengines/watermark route. Applies a watermark (behind page content) to one or more PDF files. Supports text, image, or pdf sources. Also available as optional form fields on Chromium, LibreOffice, merge, and split routes. Configurable via --pdfengines-watermark-engines (default: pdfcpu,pdftk).
• Stamp: Added POST /forms/pdfengines/stamp route. Applies a stamp (on top of page content) to one or more PDF files. Same source types and integration points as watermark. Configurable via --pdfengines-stamp-engines (default: pdfcpu,pdftk).
• Rotate: Added POST /forms/pdfengines/rotate route. Rotates pages by 90°, 180°, or 270° with optional page selection. Also available as optional form fields (rotateAngle, rotatePages) on all composite routes. Configurable via --pdfengines-rotate-engines (default: pdfcpu, pdftk).
• Bookmarks (Read): Added POST /forms/pdfengines/bookmarks/read route. Returns the hierarchical bookmark outline from one or more PDF files as JSON. Configurable via --pdfengines-read-bookmarks-engines (default: pdfcpu).
• Bookmarks (Write): Added POST /forms/pdfengines/bookmarks/write route. Accepts either a flat list (applied to all files) or a filename-keyed map. Configurable via --pdfengines-write-bookmarks-engines (default: pdfcpu, pdftk).
• Merge Bookmark Management: The merge route now supports a bookmarks form field for custom bookmarks with automatic page-offset shifting, and an autoIndexBookmarks option to extract and reindex existing bookmarks from input files.
• PDF/A & PDF/UA Compliance: Reordered the processing pipeline so that PDF/A and PDF/UA conversion runs after watermark, stamp, and flatten operations. Also reject incompatible combinations (e.g., PDF/A + encryption, PDF/A-1/2 + embeds) with a 400 Bad Request.

LibreOffice

• Native Watermarks: Added support for LibreOffice's built-in watermark rendering during PDF export via new form fields: nativeWatermarkText, nativeWatermarkColor, nativeWatermarkFontHeight, nativeWatermarkRotateAngle, nativeWatermarkFontName, and nativeTiledWatermarkText.

API

• Download From: Extended the downloadFrom JSON schema with a field property ("watermark", "stamp", "embedded", or "") to route downloaded files to the appropriate form field bucket. The existing embedded boolean is preserved for backward compatibility.

Chore

• Updated Chromium to 146.0.7680.153-1.
• Updated Go dependencies.
