ComfyUI 0.39 to 0.42: native Flux3-image, MOSS-image, Windows ARM64 portable

ComfyUI shipped five releases between October 5 and October 19, 2026 (UTC). 0.39.0 (Oct 5) adds `--offline` and `--disable-partner-nodes` flags and deprecates `--disable-api-nodes`. The release notes give only the flag names. The linked pull request (#16672) explains them. `--disable-partner-nodes` only hides partner (API) nodes. `--offline` also disables them and sets a Content-Security-Policy header that blocks outbound requests from the web frontend. `--disable-api-nodes` now acts as an alias for `--offline` and logs a deprecation warning. The same release disables pinned memory automatically on integrated GPUs and adds a FLUX 3 Image partner node for BFL. 0.40.0 (Oct 13) adds an ARM64 NVIDIA portable build. It ships as `ComfyUI_windows_portable_nvidia_arm64.7z`, so it is a Windows package. The release also improves low-VRAM performance of the Qwen 3.5 LLM, removes the `cryptography` package dependency and adds governance enforcement for custom nodes. The governance pull request (#16167) says nothing changes for normal installs; it applies to governed builds that ship a signed policy. 0.41.0 (Oct 15) adds native Flux3-image model support (PR #17064), separate from the 0.39.0 partner node. That pull request says it uses a Qwen3-VL-4B text encoder and the existing Flux2 VAE. 0.41.0 also adds MiniMax-H3 LightVAE support. 0.42.0 (Oct 18) adds MOSS-image support, a second part of Qwen 3.x performance improvements, and loading of embedding models onto Qwen3.5. PR #17170 makes ComfyUI report no fp8, nvfp4, mxfp8 or int8 compute support on the CPU device. 0.42.1 (Oct 19) fixes crashes some users hit when running the MOSS image template workflow.
