 # Changelog
 
+## v0.31.0
+
+- [#137](https://github.com/justjake/quickjs-emscripten/pull/137)
+  - Add `quickjs-for-quickjs`, a package that can run inside quickjs, so you can put quickjs inside your quickjs.
+  - **Possibly breaking**: Fix a build system bug that made commonjs or esm variants include both types, thus being larger than they needed to be. After upgrading a variant to this release, you should verify that it can be imported/required as expected. You may need to add additional variants if you were using an "esm" variant from both cjs and esm.
+
 ## v0.30.0
 
 - [#200](https://github.com/justjake/quickjs-emscripten/pull/200) Inspect and iterate handles, equality, changes to result types, changes to debug logging.

+
+Compiled to pure Javascript, no WebAssembly required.
+
+This generated package is part of [quickjs-emscripten](https://github.com/justjake/quickjs-emscripten).
+It contains a variant of the quickjs WASM library, and can be used with quickjs-emscripten-core.
+
+```typescript
+import variant from "@jitl/quickjs-asmjs-mjs-release-sync"
+import { newQuickJSWASMModuleFromVariant } from "quickjs-emscripten-core"
+const QuickJS = await newQuickJSWASMModuleFromVariant(variant)
+```
+
+This variant was built with the following settings:

+## Library: quickjs
+
+The original [bellard/quickjs](https://github.com/bellard/quickjs) library.
+
+Version [2024-02-14+36911f0d](https://github.com/bellard/quickjs/commit/36911f0d3ab1a4c190a4d5cbe7c2db225a455389) vendored to quickjs-emscripten on 2024-06-15.
+
+## Release mode: release
+
+Optimized for performance; use when building/deploying your application.
+
+## Exports: import
+
+Exports the following in package.json for the package entrypoint:
+
+- Exports a NodeJS-compatible ESModule. Cannot be imported synchronously from a NodeJS CommonJS module.
+
+## Extra async magic? No
+
+The default, normal build. Note that both variants support regular async functions.
+
+## Single-file, or separate .wasm file? asmjs
+
+The C library code is compiled to Javascript, no WebAssembly used. Sometimes called "asmjs". This is the slowest possible option, and is intended for constrained environments that do not support WebAssembly, like quickjs-for-quickjs.
