 # Changelog
 
+## 2025-11-25 - 2.2.1 - fix(core)
+Normalize binary data handling across registries and add buffer helpers
+
+- Add core/helpers.buffer.ts with isBinaryData and toBuffer utilities to consistently handle Buffer, Uint8Array, string and object inputs.
+- Composer: accept Uint8Array uploads, convert to Buffer before ZIP extraction, SHA-1 calculation and storage.
+- PyPI: accept multipart file content as Buffer or Uint8Array and normalize to Buffer before processing and storage.
+- Maven: normalize artifact body input with toBuffer before validation and storage.
+- OCI: improve upload id generation by using substring for correct random length.
+
 ## 2025-11-25 - 2.2.0 - feat(core/registrystorage)
 Persist OCI manifest content-type in sidecar and normalize manifest body handling
