M9 perf: signature revalidation after edits reuses the signed ranges' digests and the parsed signed revision (DigestCache per document) and no longer scans the file for revision markers: a comment edit on a 120 MB signed file takes 6 ms instead of 84 ms; cos exposes xref entries so unchanged objects are skipped when diffing revisions

M8.5/M8.6/M8.7: Redact a PDF: new content crate (L2: content-stream operators with spans, inline images, serializer, matrices) and redact crate (L4): Redact annotations; apply removes glyphs (TJ displacement keeps the rest in place; simple, composite/CMap and Type 3 fonts), clears covered image pixels (or removes images it can't re-encode), removes or clips vectors and shadings, rewrites form XObjects copy-on-write, removes overlapping comments, links and fields, draws the boxes with overlay text, then verifies and fails closed; redacted documents save as a full rewrite. Search & Redact text and patterns (phone, e-mail, credit card, SSN, dates). UI: Redact tool (text or box), Redact pages, Find text and redact, Set properties, Clear all / Redact all with confirmation; redact_mark/redact_apply/redact_clear tools (57 tools). Fix: deleting a field when /AcroForm is a direct dictionary

M8.1: Protect Using Password: engine Protect/RemoveProtection edits (Acrobat permission levels: printing, changes, copy, screen readers; AES-256/AES-128/RC4 compatibility; encrypt-except-metadata), per-state passwords on the undo stack, owner rights kept after saving, pending security in Document Properties; dialog matching Acrobat's (Viewing/Editing, strength meter, Advanced Options), protect.password/protect.remove commands; doc_protect/doc_unprotect tools (passwords never echoed). Fixes: saving a password-protected document failed to rebase on the encrypted file; DocInfo.encrypted was false for every decrypted file
