 All notable changes to GTD Calendar are documented here. Versions follow the plugin's `manifest.json` / `package.json` version, which also matches the published npm releases.
 
-## 2.2.0 — Unreleased
+## 2.2.1 — Unreleased
+
+### Matrix completion action
+
+- Editable Skeleton and Eisenhower matrix move menus now include **Done**.
+- Done completes native to-dos and applies the configured `done-tag` to
+  ordinary notes, removing the completed card from the matrix.
+- Successful matrix moves now perform a settled follow-up refresh after the
+  immediate redraw, avoiding stale cards while Joplin publishes tag/to-do writes.
+
+## 2.2.0
 
 ### Tag-driven editable Skeleton matrix
