+# QuickJS Version 3.0 — Breaking Changes Ahead!
+
+We're excited to announce **Version 3.0** of `@sebastianwessel/quickjs`! This release introduces a **breaking change** in how the **WASM module** is loaded, improving **security** and providing a **clearer separation** between the runtime and its dependencies.
+
+> If you're upgrading from a previous version, please read this post carefully to avoid runtime errors.

+
+## WASM Module Must Now Be Explicitly Imported
+
+To comply with **stricter security restrictions in Node.js** and to allow better customization, the `loadAsyncQuickJs` and `loadQuickJs` functions **no longer provide default module fallbacks**.
+
+### New Required Usage (Async):
+
+```ts
+import variant from "@jitl/quickjs-wasmfile-release-asyncify";
+const { runSandboxed } = await loadAsyncQuickJs(variant);
+```
+
+### New Required Usage (Sync):
+
+```ts
+import variant from "@jitl/quickjs-ng-wasmfile-release-sync";
+const { runSandboxed } = loadQuickJs(variant);
+```
+
+### Old Usage (No Longer Supported):
+
+```ts
+// ❌ These will now throw an error
+const { runSandboxed } = await loadAsyncQuickJs();
+const { runSandboxed } = loadQuickJs();
+```
+
+This change ensures that the host application **explicitly declares which WASM variant** it intends to use, improving clarity and maintainability — especially in advanced environments like bundlers or serverless runtimes.
