 # Changelog
 
+## 2026-05-08 - 3.3.1 - fix(virtualstream)
+support reconstituting smartjson encoded binary stream chunks
+
+- Add VirtualStream handling for EncodedBuffer payloads encoded as base64.
+- Keep support for JSON-serialized Buffer payloads and add test coverage for both binary chunk formats.
+- Add release registry configuration for package publishing.
+
 ## 2026-03-03 - 3.3.0 - feat(typedrouter)
