You need nightly (git, not portable or Desktop), or wait for 0.37.0

Which "last comfyui version" do you mean?

This:
https://github.com/Comfy-Org/ComfyUI
is five days old (v.036.0), if you don't update per "git pull" in your main ComfyUI folder. Do that git pull, then you see that e.g. the requirements.txt file is from today. The version nr. in the console will still show 0.36.0, that doesn't change until new release can be found in https://github.com/Comfy-Org/ComfyUI .

Or do you use another Comfy version, e.g. desktop? Then you have to wait a few days.

We don't know if user has the manager to switch to nightly.

What's the qwen3.5_9b_qwen_image_2.1_pe_t2i.int8_convrot.safetensors for?

that's for prompt enhancing t2i qwen image edit 2.1 only. or will be soon.

text encode qwen 21 or qwen cache node missing

For anyone still missing TextEncodeQwenImage21 / QwenImage21Cache: both nodes are in ComfyUI v0.37.0 (released Sept 21) and later. A Desktop or portable build older than that won't have them until it updates.

Which file goes in which loader, since this keeps coming up here and in #4:

If you turn the prompt enhancer on, note that the official templates in the current release (comfyui-workflow-templates 0.11.70) run it without its system prompt. A fix was merged upstream on Sept 30 (Comfy-Org/workflow_templates PR 1298) but is not in a released templates package yet. Workflows saved from the older templates keep the problem.

We made a free checker for these mistakes. Drop an exported workflow (UI or API JSON) on the page and it lists files in the wrong loader, nodes your ComfyUI version lacks, and a PE running without its system prompt.
