What's Changed in PdfBooklet 3.1.7

PDF Engine & Imposition

• Resolve inherited /Rotate and /CropBox attributes from parent /Pages tree nodes (ISO 32000 compliance).
• Fix Form XObject overlay placement to preserve external clickable /URI links and handle non-zero CropBox origins.
• Fix 270-degree auto-rotation translation offset and separate manual rotations from base rotations.
• Restore outward physical Creep adjustment calculation for both LTR and RTL layouts.
• Enforce absolute physical millimeters on the output sheet for Creep and manual translations (1 mm in UI = 1 mm on paper).
• Reuse authenticated PDF readers in batch rendering worker for user-password protected documents.
• Support descending page ranges (e.g. 10-8) in the page selection entry box.
• Fix bounds checks and blank cell padding in non-booklet layouts (2-up, 4-up, Copies).
• Fix crashes when loading multi-sheet custom imposition templates (====) in User Defined mode.
• Fix case-sensitivity mismatch when loading pageSelection from .ini project files.
• Safe fallback when reference page index exceeds document page count.

Packaging & Performance

• Migrate Windows build and GitHub Actions CI workflow to modern MSYS2 UCRT64 environment.
• Prune unused AV1/AVIF codecs, Tcl/Tk data, and docs from the Windows bundle (-31% size reduction, down to ~119 MB uncompressed / 48.9 MB portable ZIP).
• Dynamically bundle locales, icons, and Glade UI assets into Debian packages (/usr/share/pdfbooklet).
• Update stdeb.cfg and package_deb.py dependencies for modern Linux distributions.

UI & Localization

• Enforce LC_NUMERIC='C' to prevent decimal comma parsing errors on Spanish and European locales.
• Constrain vertical stretching on "Reference page" and "Creep adjustment" entry fields in Glade.
• Fix UI state errors when toggling transformation scope radio buttons without an active cell selection.
• Update application icons to official 64x64 RGBA assets.
