+
+## .fabro file extension
+
+Workflow files now use the `.fabro` extension instead of `.dot`. This gives workflows a distinct identity and avoids conflicts with Graphviz `.dot` files. Existing `.dot` files still work as a fallback — the engine checks for `graph.fabro` first, then falls back to `graph.dot`.
+
+```toml
+[workflow]
+graph = "workflow.fabro"
+```
+
+<Warning>
+**Breaking change.** Workflow files have been renamed from `.dot` to `.fabro`. Existing `.dot` files continue to work as a fallback, but new projects should use `.fabro`.
+</Warning>
+
+## Smarter human gates
+
+Human-in-the-loop gates now show the previous stage's output before prompting, so you can see what the agent produced before deciding what to do next. Gates with only a freeform edge also skip the multiple-choice menu and go straight to a text input, making conversational loops like REPL workflows feel more natural.

+
+## Rewind workflow runs
+
+You can now rewind a workflow run to an earlier checkpoint and resume from there. This is useful when a later stage goes off-track and you want to try again from a known-good point without restarting the entire workflow.
+
+```bash
+fabro rewind --run-branch fabro/runs/my-run --target plan@2
+```
+
+Target a specific node by name, `node@visit` for a particular visit count, or `@ordinal` for a checkpoint index. The command rewinds both the metadata and run branch refs, and optionally pushes to the remote.
+
+## fabro workflow list
+
+A new `fabro workflow list` command shows all available workflows in your project. Workflows are grouped by source (project vs. user-level), with descriptions pulled from each workflow's goal.
+
+```bash
+fabro workflow list
+```
+
+## More
+
+<Accordion title="Improvements">
+- Default Daytona sandbox now uses the `daytona-medium` snapshot with standard dev tools pre-installed
+- Workflow list output shows grouped sections with aligned columns and truncated descriptions
+- Added Dark Factory documentation page
+- Added workflow diagram to README

+- Fixed missing `git_commit_sha` in run branch commit messages
