+Codex Context Window v0.3.1 improves how the plugin is described and classified without changing its runtime behavior.
+
+The plugin remains independently distributed through the `codex-context-window` marketplace. Its manifest now exposes clearer publisher and project metadata, explicitly references the bundled lifecycle hooks, and places the plugin in the Developer Tools category.
+
+## What changed
+
+- **Clearer publisher metadata** — the manifest now links the publisher name to its GitHub profile.
+- **Project website in plugin details** — the interface metadata links directly to the public repository.
+- **Explicit hook declaration** — the manifest points to `./hooks/hooks.json` instead of relying only on default discovery.
+- **More accurate category** — Codex now presents the plugin under Developer Tools rather than Productivity.
+
+The native hook implementation and the context-window signals it produces are unchanged.
+
+## Upgrade
+
+Refresh the marketplace and reinstall the plugin:
+
+```bash
+codex plugin marketplace upgrade codex-context-window
+codex plugin add codex-context-window@codex-context-window
+```
+
+Then open a new chat or restart Codex so the refreshed plugin is loaded.
+
+## Compatibility
+
+This release has no breaking configuration changes and supports the same macOS, Linux, and Windows targets as v0.3.0.
+
+**Full Changelog**: https://github.com/nleononline/codex-context-window/compare/v0.3.0...v0.3.1
