Release v1.0.2-rc1 - The University Edition

[1.0.2-rc1] - 2026-08-13

This release candidate focuses on controller rebinding, menu and ultrawide stability, and Expansion Kit Course Edit
recovery. It is not yet a stable 1.0.2 release. I apologize for the delay of it. But I just returned to a new semester in university recently and my free time was butchered.

Fixed for testing

• Controller rebinding now blocks menu gamepad navigation for the entire mapping operation, so shoulder inputs can be
  assigned without changing menu tabs (#16).
• Multi-viewport docking is disabled by default to avoid the secondary-window path associated with menu and tooltip
  crashes. It remains available as an opt-in developer setting that applies after restart ([#7](https://github.com/
  /issues/7)).
• Oversized offscreen framebuffers are scaled uniformly to the active renderer's texture limit. Direct3D 11 also
  creates replacement color and depth resources before replacing the working framebuffer, targeting the reported 32:9
  fullscreen crash (#17).
• Expansion Kit custom courses now build their runtime segment data in the buffer expected by Course Edit and race
  setup (#12).
• Expansion Kit file-list failures now complete with a dismissible result instead of leaving Course Edit stuck waiting
  for an operation that has already failed.
• A missing MFS root directory can be repaired without formatting the rest of the disk save. Full formatting still
  requires explicit one-shot authorization from the Workshop menu.
• Disk sidecars now use the application's saves directory consistently on Windows and Linux. Linux can copy legacy
  sidecars from the old working-directory location when no canonical save exists.

Known issues and test focus

• A newly saved Course Edit track can be written to the .gdd sidecar but still fail to appear in File > Load.
  Immediate and post-restart loading remain under investigation, so custom-course persistence is not yet cleared for the
  stable 1.0.2 release (#12).
• Create Machine needs a complete save, restart, and reload test before its persistence path is considered release-
  ready (#10).
• The menu, tooltip, and extreme-resolution fixes still need confirmation on the hardware configurations that
  originally reported them (#7, [#17](https://github.com/Zorkats/G-
  Diffuser/issues/17)).

Release-candidate test checklist

• Rebind L, R, and Z while controller menu navigation is enabled.
• Open the enhancement menu, inspect tooltips, and enter and leave fullscreen.
• Test 5120x1440 with increased internal resolution on Direct3D 11.
• Save a custom course, find it in File > Load, restart, load it again, and enter a race.
• Save a custom machine, restart, and load it again.
