+
+Fixed [#7192](https://github.com/biomejs/biome/issues/7192):
+`noUnusedPrivateClassMembers` now treats private members in compound assignments (+=, -=, ??=, etc.) as used,
+while plain assignments (=) do not count as usage.
+
+Example that is now correctly flagged:
+
+```typescript
+class App {
+  #persistenceRequest: Promise<boolean> | undefined;
+  saveData() {
+    this.#persistenceRequest +=  2;
+  }
+}
+```
