• Atomiswave and NAOMI conversion GDIs are now auto-detected and rejected for unsupported operations (see Issue 23).
• GDIs with relocated data tracks are now rejected for CUE/BIN conversion instead of producing broken output (see Issue 24).

Version 2.1.4 (2026-07-03)

• Fixed broken CUE/BIN output for some games with CD audio tracks, along with support for GDI files whose track filenames contain spaces and automatic detection and rejection of the early, short-lived Redump GDI format (see Issue 20).

Version 2.1.2 (2026-06-09)

• Radio buttons and checkboxes now properly disabled after user clicks "Build Patch" (see Issue 15).
• Dialog boxes now have a maximum width, forcing clean text wrapping everywhere (see Issue 16).
• Tooltip text added to several clickable elements in IP.BIN Editor (see Issue 17).
• Customize IP.BIN section's alignment adjusted for consistency (see Issue 18).

Version 2.1.1 (2026-05-17)

• New batch mode added to "Converter" tab (see Issue 12).
• External DATs can now be used for disc image convert operations (see Issue 13).
• "Build Patch" tab's IP.BIN modifications section redesigned (see Issue 14).

Version 2.0.1 (2026-05-05)

• Fixed potential auto-updater breakage in the future due to build pipeline version mismatch (see Issue 4).

Version 2.0.0 (2026-05-04)

• Complete rewrite, combining the patcher and patch builder into a single cross-platform application (Windows, Linux, macOS).
• Removed all dependencies on external helper utilities, natively implementing all disc-image extract, rebuild, and binary diffing operations.
• Added support for CHD as a source disc image format (automatically decompressed and, if necessary, converted to GDI from CUE/BIN).
• Added built-in auto-update on Windows and Linux.
• Patched disc images and DCP files are now byte-identical across platforms for the same inputs, finally delivering reliable checksums.
