v0.4.0

What's new

• Inspect a PDF's embedded files and attachments, and pull any one out to disk
• Read a document's metadata - the Info dictionary and the XMP packet
• Look inside fonts: encoding, CMap, and the full glyph mapping, with warnings for broken mappings
• Break down digital signatures into signer, certificate chain, and the byte ranges they cover - it never claims a signature is trusted, only shows what's there
• Check a PDF against structural PDF/A and PDF/UA rules, and jump straight to the offending object in the app
• Compare two PDFs: a structural diff in the terminal, or side-by-side in the app
• New validate and diff commands return a simple pass / issues-found / error exit code for scripting
• Command-line output is now plain, readable text by default - add --json when you need machine-readable output (--pretty to indent it)
• A new usage guide covers every pdfdebug command and flag
• Double-clicking a PDF now reliably opens it, even while the app is still starting up
• Digital signature decomposition now reads every embedded certificate reliably
• More stable on Linux and macOS thanks to an updated app runtime

• Inspect PDFs straight from the terminal: dump the structure, look up any object, follow references, and view a page's contents

• Safer when several PDFs are open at once
• More accurate reading of what's actually inside a document
