A backend that carries a zero-copy container path lost it: wrap_attn offers that path only when the OVERRIDE has the attribute, so dropping it selects the backend, computes the right answer, and never uses the thing the backend exists for. ComfyUI forwards it in set_model_optimized_attention; now so do we. An unknown encoder family fell back to stable_diffusion and reported success. A family mismatch in this project reads as an unrelated fault, so it refuses and lists what this ComfyUI actually knows. fp16 accumulation is one flag for the whole interpreter, so a per-node checkbox cannot mean "this model": a second loader changes the first model's maths, and loader caching outlives the run. It cannot be scoped, so it is at least no longer silent -- every transition says what it really covers. The honest fix is to move it to a machine-level setting.

ComfyUI-FunPack v5 — "Cunning Cranberry"
FunPack v4.0.0 is going to be the latest release of classic FunPack. Next update is another milestone update, or shall I say, a full rework.
Maintenance of current FunPack became a mess — forgetting to add or remove buttons from/to UI, finding functions that don't do anything but still present in the code absolutely randomly, trying to keep the UI neat while it has no strict boundaries on how it should look like, and of course — making it easy for users to understand how FunPack operates and how you can operate it — this is all time, money and token-consuming.
General idea behind the FunPack v5 rework is writing it from scratch, with a new architecture where a feature can't be forgotten, where a wire can't be missed, where one failing module never stops whole process from executing. Loaders and features would tell the UI by themselves what sorts of inputs they need and where to put it — and UI will compose them according to design guidelines it would have. Samplers would become independent from features — if a feature is available and enabled, sampler would call it. If it's not — it gets skipped and doesn't even appear in the UI so it won't confuse you.
Most of this comes from a FunUI backend draft that got shelved after understanding on how much time has to be invested into polishing it. Without a community support and wide usage it would become another dead project only one person in the world needs but no one else.
Come to think of it, FunPack already became something alike, with an exception — this project is more than alive, and while I can, I will support it.
Final goal is to make FunPack an ultimate answer for a novice's question "I don't know how to generate — what do I install and how do I start?" and for a professional's question "I need a UI with all the cutting edge techniques available on day 0 — which one?"
Preparation for the v5 had started.
FunPack v5.0 "Cunning Cranberry" — coming fall 2026.
This branch is a clean start. Classic FunPack lives on main.
