Introduction

ComfyUI v0.40.0 is tagged and live. The GitHub Release landed at 2026-10-13T21:29Z (about 05:29 MYT Oct 14) with fresh Windows portables — including a first NVIDIA ARM64 build — and a full changelog from v0.39.0. The headline for makers: native LoRA stack loader nodes, CameraAngle / CreateCameraInfo for shot prompts, H3 single-image decode polish, and a partner-node wave that finally sits inside a pin-able tag.

Release: ComfyUI v0.40.0 · Compare: v0.39.0…v0.40.0

Grab the build

Windows portables are attached to the tag:

  • ComfyUI_windows_portable_nvidia.7z
  • ComfyUI_windows_portable_nvidia_cu126.7z
  • ComfyUI_windows_portable_nvidia_arm64.7z (new in this tag)
  • ComfyUI_windows_portable_amd.7z
  • ComfyUI_windows_portable_intel.7z

Git installs can pin the tag directly:

cd ComfyUI
git fetch --tags
git checkout v0.40.0
pip install -r requirements.txt

Native graph tools: LoRA stacks and cameras

The open-weights side of this tag is quieter than a new backbone, but it is the kind of plumbing you feel every session.

  • Native LoRA stack loaders (#16309, CORE-186): load several LoRAs with per-row strengths inside core nodes instead of reaching for a custom stack pack.
  • CreateCameraInfo (#14964) and CameraAngle (#16251): build camera_info state and shot-prompt outputs so 3D / video graphs can speak about angle and framing with one shared widget language.
  • H3 single-image decode (#16881): MiniMax H3 single images decode as the first latent of a clip, which cleans up stills-from-video style graphs.
  • LatentOperationBlend plus start/end percent on latent apply ops (#16923)
  • LoRAs can replace per-layer attention configs on a model (#16880)
  • EXR save compression (#16948), EXR asset previews from SaveImageAdvanced (#16898), and faster GLB texture PNG compression (#16867)
  • Custom-node governance enforcement (#16167) so Manager / published nodes follow the house rules more tightly
  • An ARM64 NVIDIA portable (#16985) for Spark-class Windows boxes
  • Frontend package bumped to 1.55.17, workflow templates through v0.11.82, embedded docs to v0.5.14

Assets toggles also settled in this tag: the Windows standalone build turns assets on (#16928), while the default CLI path keeps them opt-in via --enable-assets after a brief on-by-default experiment (#16884, #16929).

Partner nodes in the pin-able tray

These are paid API nodes. Several already had day-0 Dispatches when they merged to master; the new part today is that they live in a versioned release you can pin:

  • Nano Banana 2.1 (#16822): text-to-image and edit in one Google partner node, 1K–4K, thinking levels MINIMAL / MEDIUM / HIGH, up to 14 reference images — docs
  • Vidu Q4 Preview (#16849): image-to-video and reference-to-video, 3–16 s, 540p–4K, native audio, up to 15 refs — docs
  • Clarity AI Crystal Upscaler (#16817): faithful upscale up to 100 MP, scale 1–200×, creativity 0–10 — docs
  • Kling Virtual Try-On (#16844): person + garment → outfit swap inside the graph
  • Quiver SVG V2 (#16775): per-model text-to-SVG / image-to-SVG; original Quiver nodes deprecated
  • HeyGen Video 1.0 → 2K (#16876)
  • Higgsfield Genjutsu Motion Transfer (#16913) and Fish Audio Drama 3 (#16999) — already covered on their own launch days; now version-locked with the rest

We wrote separate Dispatches for Nano Banana 2.1, Vidu Q4, Kling Try-On + Crystal, Genjutsu, and Drama 3. Treat this article as the release pin, not a re-scoop of every model card.

Same-day companion: NVIDIA RTX VFX nodes

Minutes after the tag,

flagged official NVIDIA RTX Spark VFX nodes for local RTX GPUs: Video Super Resolution (upscale / denoise / deblur), Video Frame Generation, and SDR→HDR, with first-class EXR support. That pack is a separate Manager install (comfyui_nvidia_rtx_nodes / Nvidia_RTX_Nodes_ComfyUI), not a core v0.40.0 PR — see the ComfyUI blog post. Pair it with this portable if you want the hardware path, not the cloud partner tray.

Conclusion

ComfyUI v0.40.0 is a maker-friendly pin: native LoRA stacks and camera widgets, an ARM64 NVIDIA portable, H3 stills that behave in latent space, and a partner tray (Nano Banana 2.1, Vidu Q4, Crystal, Kling Try-On, Genjutsu, Drama 3) you can cite by version. Pull a portable or check out the tag, then reopen the graph you left hanging on nightly.
