 # Changelog

+## 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
+
+- AuthManager: create and validate OCI JWTs signed with HMAC-SHA256 (header.payload.signature). Signature verification, exp/nbf checks and payload decoding implemented.
+- PyPI: improved Simple API handling (PEP-691 JSON responses returned as objects), Simple HTML responses updated, upload handling enhanced to support nested/flat multipart fields, verify hashes (sha256/md5/blake2b), store files and return 201 on success.
+- RubyGems: upload flow now attempts to extract gem metadata from the .gem binary when name/version are not provided, improved validation, and upload returns 201. Added extractGemMetadata helper.
+- OCI: centralized 401 response creation (including proper WWW-Authenticate header) and HEAD behavior fixed to return no body per HTTP spec.
+- SmartRegistry: use nullish coalescing for protocol basePath defaults to avoid falsy-value bugs when basePath is an empty string.
+- Tests and helpers: test expectations adjusted (Content-Type startsWith check for HTML, PEP-691 projects is an array), test helper switched to smartarchive for packaging.
+- Package.json: added devDependency @push.rocks/smartarchive and updated dev deps.
+- Various response normalization: avoid unnecessary Buffer.from() for already-serialized objects/strings and standardize status codes for create/upload endpoints (201).
