 # 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
+
+- Add getOciManifestContentType(repository, digest) to read stored manifest Content-Type
+- Store manifest Content-Type in a .type sidecar file when putOciManifest is called
+- Update putOciManifest to persist both manifest data and its content type
+- OciRegistry now retrieves stored content type (with fallback to detectManifestContentType) when serving manifests
+- Add toBuffer helper in OciRegistry to consistently convert various request body forms to Buffer for digest calculation and uploads
+
+## 2025-11-25 - 2.1.2 - fix(oci)
+Prefer raw request body for content-addressable OCI operations and expose rawBody on request context
+
+- Add rawBody?: Buffer to IRequestContext to allow callers to provide the exact raw request bytes for digest calculation (falls back to body if absent).
+- OCI registry handlers now prefer context.rawBody over context.body for content-addressable operations (manifests, blobs, and blob uploads) to preserve exact bytes and ensure digest calculation matches client expectations.
+- Upload flow updates: upload init, PATCH (upload chunk) and PUT (complete upload) now pass rawBody when available.
+
+## 2025-11-25 - 2.1.1 - fix(oci)
+Preserve raw manifest bytes for digest calculation and handle string/JSON manifest bodies in OCI registry
+
+- Preserve the exact bytes of the manifest payload when computing the sha256 digest to comply with the OCI spec and avoid mismatches caused by re-serialization.
+- Accept string request bodies (converted using UTF-8) and treat already-parsed JSON objects by re-serializing as a fallback.
+- Keep existing content-type fallback logic while ensuring accurate digest calculation prior to storing manifests.
+
+## 2025-11-25 - 2.1.0 - feat(oci)
+Support configurable OCI token realm/service and centralize unauthorized responses
+
+- SmartRegistry now forwards optional ociTokens (realm and service) from auth configuration to OciRegistry when OCI is enabled
+- OciRegistry constructor accepts an optional ociTokens parameter and stores it for use in auth headers
+- Replaced repeated construction of WWW-Authenticate headers with createUnauthorizedResponse and createUnauthorizedHeadResponse helpers that use configured realm/service
+- Behavior is backwards-compatible: when ociTokens are not configured the registry falls back to the previous defaults (realm: <basePath>/v2/token, service: "registry")
+
 ## 2025-11-25 - 2.0.0 - BREAKING CHANGE(pypi,rubygems)
 Revise PyPI and RubyGems handling: normalize error payloads, fix .gem parsing/packing, adjust PyPI JSON API and tests, and export smartarchive plugin
