[2.0.0] - 2026-09-11

Critical change that ensures reliablity and should have no bad side effects, but when you see any, please report:

DICT, LIST, SET and Data List nodes (plus the DICT/LIST-taking STRING nodes) now degrade gracefully when their data source is not connected (None) instead of raising: read/query nodes return their natural "no data" result (the get default, an empty list, False, 0, None), and transform nodes behave as if given an empty container.
"save IMAGE to file" and "save IMAGE+MASK to file": format is now a dropdown (still connectable as a STRING) whose entries are derived from the formats the installed Pillow/image plugins can actually write (RGB node offers them all, IMAGE+MASK only alpha-capable ones); every batch frame is written instead of only the first; and path can be switched to ComfyUI-style filename_prefix mode via a toggle, resolved through ComfyUI's own folder/file helpers (auto-numbered under the output dir); both modes accept ComfyUI templates such as %date:yyyy-MM-dd%

Backward compatible changes:

Add a "continue if not empty" flow-control node: it passes a value through unchanged when it is non-empty, and blocks execution (via an execution blocker) when the value is empty. It is list-aware (INPUT_IS_LIST / OUTPUT_IS_LIST), so it is immune to ComfyUI's empty-input batching crash and passes data lists through unchanged. By default the block is silent; an optional message can be set to show a dialog. Use it before nodes that cannot handle an empty input (e.g. a node receiving an empty Data List) to stop execution instead of failing.
Add "create DICT from JSON string" and "create LIST from JSON string" nodes to parse a multiline JSON object/array into a DICT/LIST

Add optional additional input for image saving to also save the prompt when provided
Enhance in line documentation
