 # Changelog
 
+## 2025-11-25 - 2.2.2 - fix(npm)
+Replace console logging with structured Smartlog in NPM registry and silence RubyGems helper error logging
+
+- Replaced console.log calls with this.logger.log (Smartlog) in ts/npm/classes.npmregistry.ts for debug/info/success events
+- Converted console.error in NpmRegistry.handleSearch to structured logger.log('error', ...) including the error message
+- Removed console.error from ts/rubygems/helpers.rubygems.ts; gem metadata extraction failures are now handled silently by returning null
+
+## 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
+
+- Rename error payload property from 'message' to 'error' in PyPI and RubyGems interfaces and responses; error responses are now returned as JSON objects (body: { error: ... }) instead of Buffer(JSON.stringify(...)).
+- RubyGems: treat .gem files as plain tar archives (not gzipped). Use metadata.gz and data.tar.gz correctly, switch packing helper to pack plain tar, and use zlib deflate for .rz gemspec data.
+- RubyGems registry: add legacy Marshal specs endpoint (specs.4.8.gz) and adjust versions handler invocation to accept request context.
+- PyPI: adopt PEP 691 style (files is an array of file objects) in tests and metadata; include requires_python in test package metadata; update JSON API path matching to the package-level '/{package}/json' style used by the handler.
+- Fix HTML escaping expectations in tests (requires_python values are HTML-escaped in attributes, e.g. '&gt;=3.8').
+- Export smartarchive from plugins to enable archive helpers in core modules and helpers.
+- Update tests and internal code to match the new error shape and API/format behaviour.
+
 ## 2025-11-25 - 1.9.0 - feat(auth)
 Implement HMAC-SHA256 OCI JWTs; enhance PyPI & RubyGems uploads and normalize responses
