3.1a Windows & Linux

v3.1a (04/02/2026) — public

• fixed: decompression per-file display showed 0 KB → X KB 0.0% instead of
  the correct sizes and ratio; root cause was merge_jpeg() assigning the JPEG
  output size to pjgfilesize instead of jpgfilesize — also caused speed and
  ratio to read 0.00% in -v1/-v2 verbose mode and in batch summaries
• fixed: -ver save/restore used int instead of int64_t for
  saved_jpgsize/saved_pjgsize, causing size truncation on files ≥ 2 GB
• fixed (XP): when -th>1 was requested on the XP build, the fallback
  sequential path omitted acc_jpgsize/acc_pjgsize accumulation for PJG
  files, leaving batch decompression stats at zero
• fixed (Windows): --no-color skipped SetConsoleOutputCP(CP_UTF8), causing
  Unicode characters (✓ ✗ → ░ █ braille spinner) to render as garbage in
  cmd.exe; UTF-8 codepage is now set unconditionally on Windows
• fixed (Windows): FileReader/FileWriter used long/ftell on the Windows
  path, which is 32-bit even on x64 and overflows for files > ~2.14 GB;
  replaced with _fseeki64/_ftelli64 in both source/ and source4xp/
• fixed: list subcommand batch summary incorrectly displayed
  decompressed: N PJG; now correctly shows listed: N PJG
