+4.0.2 (in development)
 ----------------------
 - Added support for compiling AVX2 intrinsics, 256-bit wide intrinsic is emulated
   on top of 128-bit Wasm SIMD instruction set. (#23035). Pass `-msimd128 -mavx2`
   to enable targeting AVX2.
 - The system JS libraries in `src/` were renamed from `library_foo.js` to
   `lib/libfoo.js`. They are still included via the same `-lfoo.js` flag so
   this should not be a user-visible change. (#23348)
+
+4.0.1 - 01/17/25
+----------------
 - The minimum version of node required to run emscripten was bumped from v16.20
   to v18.  Version 4.0 was mistakenly shipped with a change that required v20,
   but that was reverted. (#23410)
