+## v8 - What's new
+
+> [!IMPORTANT]
+> actions/download-artifact@v8 has been migrated to an ESM module. This should be transparent to the caller but forks might need to make significant changes.
+
+- Downloads will check the content-type returned to determine if a file can be decompressed and skip the decompression stage if so. This removes previous failures where we were trying to decompress a non-zip file. Since this is making a big change to the default behavior, we're making it opt-in via a version bump.
+- Users can also download a zip file without decompressing it with the new `skip-decompress` flag.
+
+- Chore: we've bumped versions on a lot of our dev packages to get them up to date with the latest bugfixes/security patches.
