Wan2GP Desktop Launcher v3.0.4

v3.0.4 — SageAttention swap fix (RTX 40/50): DLL import crash resolved

Hotfix for the v3.0.3 SageAttention swap. v3.0.3 installed a CUDA-12.8 SageAttention wheel that failed to import in the launcher's CUDA-13.0 / torch 2.10 environment:

ImportError: DLL load failed while importing _fused: The specified module could not be found.

Root cause

The launcher installs torch 2.10 + CUDA 13.0 (cu130). A cu128 SageAttention wheel's compiled _fused.pyd links against CUDA 12.8 runtime DLLs that are absent under cu130 → the module cannot load. The swap was pip-successful but runtime-broken.

Fix

The swap now targets the CUDA-13.0-native, fp8-fixed wheel:
sageattention-2.2.0+cu130torch2.10.0andhigher.post6-cp310-abi3-win_amd64.whl

• cu130 → matches the env's CUDA 13.0 runtimes, so _fused.pyd loads.
• cp310-abi3 → installs on Python 3.11 (the launcher's Python), no pip rejection.
• .post6 → the build where the fp8 out-of-bounds bug (black/noise outputs on RTX 40/50) is fixed (SageAttention #98).

All wheel URLs the launcher can emit were verified live (HTTP 200) — no broken links.

Upgrade

Install v3.0.4 (auto-updater offers it to 3.0.2 / 3.0.3 users). RTX 40/50: after updating, click Sync Kernels once (or run one Update) to land on the stable cu130.post6 wheel. RTX 30/20/older: no action needed (swap only fires on RTX 40/50 + torch ≥ 2.10).
