+# Changelog
+
+## 0.8.6 - 2026-10-23
+
+- Rebuild the WASM plugin against SWC 79 for Next.js 16.4.2 compatibility.
+- Update Rust fixture dependencies and pin the Next.js compiler regression host
+  to 16.4.2. Narrow the Next.js peer range to `~16.4.2`.
+- Add compiler and runtime regression tests for Pages Router serialization,
+  excluded props, initial props, redirects, and App Router `data-superjson`.
+- Fix the client helper's relative ESM import so packaged JavaScript can be
+  imported directly in Node.js.
+- Rebuild and test the WASM before local npm publication. Disable the GitHub
+  publishing job in favor of local releases.
