@@ -5,6 +5,25 @@ a minor version adds behaviour, a patch fixes it. The version lives in `VERSION`
 and in the bar widget's `omarchy/smoido.claude-mode/manifest.json`, and
 `scripts/bump-version.sh` changes both.
 
+## 1.13.0 — 2026-09-15
+
+Maintainability; no change in what the tool does.
+
+- **Tests.** `scripts/test.sh` (or `make test`) runs static checks, a Python
+  unit suite for `cm-json.py`, and sandboxed CLI suites against fake Ollama,
+  LM Studio, keyed-gateway and proxy servers. `--windows [host]` adds the
+  Windows suite on a remote host, in a `USERPROFILE` sandbox.
+- **Docs.** A short README; the detail lives in `docs/` (providers, live
+  sessions, design, bar widget, architecture, development) and
+  `CONTRIBUTING.md`. MIT licence.
+- **Modules.** The POSIX CLI is split into `linux/lib/*.sh`, the Windows script
+  into `lib\*.ps1`, and the bar panel into one QML file per stage. The
+  installers copy the modules and clear stale ones.
+- `scripts/bump-version.sh` keeps `VERSION` and the widget manifest in step.
+- Removed: the Arkylx Index packaging (`linux/bootstrap.sh`,
+  `scripts/build-package.ps1`).
+- Fixed: the per-project session listing used `awk`, which minimal images lack.

 ## 1.12.0 — 2026-09-15
 
 - **Providers are data.** Every gateway provider is an entry in `providers.json`:
