Massive update released today.

LinXPDF 1.3.0 - Parity Wave 1: Dynamic Stamps and Enhanced OCR

New

• Added dynamic stamp templates for {date}, {time}, {datetime}, {user}, {page}, and {pages}.
• Added ready-to-use Reviewed, Approved-by-user, Received, and Page X of Y dynamic stamp presets.
• Dynamic tokens resolve when the stamp is placed so PDFs remain portable in other viewers.
• Added automatic text-stamp font sizing for longer review/audit labels.
• Added optional recognition-only OCR text-edge sharpening for faded/soft scans.
• Added local adaptive thresholding for uneven lighting, shadows, yellowed paper, and low-contrast photocopies.
• Added isolated-speckle removal for dirty scans.

Fixes

• Fixed the clean-source audit helper used by the new 1.3 parity invariants so the final release audit runs correctly after build artifacts are removed.

Verification

• Enhanced OCR preprocessing regression passes.
• Dynamic long-text stamp regression passes.
• Focused OCR suite is 7/7 and qpdf backend suite is 55/55.
• Complete 20-target LinXPDF regression suite passes after the parity additions.

LinXPDF 1.2.3 - Exhaustive Audit and UI Hardening

Improvements

• Completed a fresh top-to-bottom source, feature, UI, backend, security, package, and runtime audit.
• Verified every public PDF backend operation has a live application call site.
• Rechecked all persistent UI actions/buttons for handler connectivity.
• Added explicit tooltips to 16 controls that were still missing them.
• Added an audit invariant so future persistent push/tool buttons must include useful tooltips.

Verification

• 20/20 complete CTest targets passed.
• qpdf backend regression suite passed.
• OCR and searchable-PDF pipeline passed.
• Redaction, signatures, timestamps/LTV, conversion, comparison, rendering, standards validation, runtime, and complete dark-UI construction passed.
• Extracted Debian package passed independent runtime and dependency validation.
• Zero unresolved ELF dependencies were found in the packaged private runtime.
• Retired pre-LinXPDF branding was verified absent.

LinXPDF 1.2.2 - Complete LinXPDF Rename

• Renamed all current application branding to LinXPDF.
• Renamed launchers, Debian identifiers, desktop integration, icon identifiers, runtime paths, environment variables, temporary prefixes, application metadata identifiers, tests, and documentation.
• Preserved the dark Mint-style UI and all existing functionality.
• Added a source/package branding audit to prevent stale old-name references.

LinXPDF 1.2.1 - Bundled veraPDF and Offline Formal Validation

New

• Bundled veraPDF Greenfield 1.30.2 CLI.
• Bundled a private trimmed OpenJDK 21 runtime.
• Added fully offline independent PDF/A/PDF/UA validation.
• Added real bundled-validator release tests.

Fixes

• Updated the parser for veraPDF 1.30+ validationResult XML reports while retaining older-report compatibility.
• Corrected PDF/A publication end-of-stream newline handling found by real veraPDF validation.
• Clarified licensing so LinXPDF's proprietary no-redistribution terms do not apply to separately licensed veraPDF/OpenJDK components.

LinXPDF 1.2.0 - Complex Content, Advanced Forms, OCR Reconstruction, and Standards

New

• Conservative reconstruction/inventory of externally authored text/vector PDF programs.
• Nested Form XObject traversal with unique-occurrence editing.
• Whole-stream safe reconstruction fallback for suitable third-party content streams.
• True hierarchical grouped radio buttons.
• Form field tab ordering and document-wide calculation order.
• Calculation, validation, formatting, keystroke, focus, blur, and activation JavaScript actions.
• Word-level OCR geometry.
• Paragraph and table layout reconstruction.
• CSV table export and mixed HTML export.
• PDF/A-2b archival conversion.
• PDF/UA-1 and PDF/UA-2 preparation for already tagged files.
• Formal veraPDF validation workflow with fail-closed status reporting.
