+## [2.1.0] - 2026-09-19
+
+Backward compatible changes:
+- "save IMAGE to file" and "save IMAGE+MASK to file" can now be used like
+  ComfyUI's built-in "Save Image" node: images written into the output (or temp)
+  folder are reported back to the frontend, so the node shows a preview of what
+  it saved and the images appear in ComfyUI's generated-images list. In addition
+  both nodes got a second `images` output that passes the images through
+  unchanged, like the built-in node does.
+  - files written somewhere else (plain `path` mode) are still saved, they just
+    cannot be previewed, as ComfyUI can only serve files from its own folders
+- Both save nodes now embed ComfyUI's workflow metadata (the API prompt and the
+  full workflow) in addition to the existing prompt metadata. Dragging a saved
+  file back onto the canvas therefore restores the workflow, while the explicitly
+  given `prompt` / `negative_prompt` remain in the `parameters` text that image
+  viewers display and that is easy to extract afterwards. This is what makes the
+  two channels worth having when a whole batch is saved from a data list: the
+  workflow then contains every prompt of the graph, whereas `parameters` always
+  holds the prompt of the image that was actually written.
+  - ComfyUI's `--disable-metadata` option suppresses both channels, exactly like
+    it does for the built-in save node
+- No widget was added, removed or reordered, so existing workflows keep their
+  saved widget values.
