From the GitHub release notes. Camera/shot control: CameraAngle node outputting camera_info and a shot prompt, CreateCameraInfo node + CameraInfoState widget (v0.40.0). Reference/latents: ReferenceMultiLatent node (v0.41.0), latent-geometry nodes, LatentOperationBlend with start/end percent. Colour pipeline: ImageSDRToHDR node (v0.41.0); Save EXR gains 16-bit float and it becomes the default for "exr", EXR compression, EXR previews in assets; higher-quality Save Video encoding defaults (v0.39.0). Local models: MiniMax H3 support work (LightVAE, LynnReal light VAE, tiled VAE blending, single images decoded as first latent), FLUX 3 Image (v0.41.0), MOSS-image (v0.42.0; v0.42.1 fixes crashes in its template), Qwen 3.x/3.5 speedups and low-VRAM fixes, native LoRA stack loader nodes. Operations/security: "governance enforcement for custom nodes" (PR #16167, v0.40.0); new --offline and --disable-partner-nodes flags, --disable-api-nodes deprecated (v0.39.0); cryptography dependency removed...

Operations/security: "governance enforcement for custom nodes" (PR #16167, v0.40.0); new --offline and --disable-partner-nodes flags, --disable-api-nodes deprecated (v0.39.0); cryptography dependency removed; CSP updated to allow blob: and data:; ARM64 NVIDIA portable and ARM Linux CI. The asset system flip-flopped inside v0.40.0 (on by default, then off unless --enable-assets, but on for the Windows standalone) - check flags after upgrading. Partner (paid API) nodes added: Nano Banana 2.1, Vidu Q4, Kling Virtual Try-On, Higgsfield motion transfer, HeyGen Video 1.0 (+2K), Ideogram 4.5, FLUX 3 Image, Grok Imagine video 1.5 lite, ElevenLabs v4/v4 Turbo, Fish Audio Drama 3, Krea 3 Image, Claude Sonnet 5.5; Luma Ray 2 deprecated, Quiver Arrow 1.x removed. Not verified: what the governance enforcement actually blocks (PR body not read).

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. GitHub release notes; features as described by the project.

Limitations: PR titles only; behaviour not tested; partner nodes are paid third-party APIs.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
