 # Changelog
 
+## 2025-11-23 - 1.7.0 - feat(core)
+Standardize S3 storage config using @tsclass/tsclass IS3Descriptor and wire it into RegistryStorage and plugins exports; update README and package dependencies.
+
+- Add @tsclass/tsclass dependency to package.json to provide a standardized IS3Descriptor for S3 configuration.
+- Export tsclass from ts/plugins.ts so plugin types are available to core modules.
+- Update IStorageConfig to extend plugins.tsclass.storage.IS3Descriptor, consolidating storage configuration typing.
+- Change RegistryStorage.init() to pass the storage config directly as an IS3Descriptor to SmartBucket (bucketName remains part of IStorageConfig).
+- Update README storage section with example config and mention IS3Descriptor integration.
+
 ## 2025-11-21 - 1.6.0 - feat(core)
 Add PyPI and RubyGems registries, integrate into SmartRegistry, extend storage and auth

 - **Composable Design**: Core infrastructure with protocol plugins

 - **Unified Authentication**: Scope-based permissions across all protocols
 - **Path-based Routing**: `/oci/*` for containers, `/npm/*` for packages, `/maven/*` for Java artifacts, `/cargo/*` for Rust crates, `/composer/*` for PHP packages, `/pypi/*` for Python packages, `/rubygems/*` for Ruby gems

 ### Storage Configuration
 
+The storage configuration extends `IS3Descriptor` from `@tsclass/tsclass` for standardized S3 configuration:
+
 ```typescript
+import type { IS3Descriptor } from '@tsclass/tsclass';
+
+storage: IS3Descriptor & {
+  bucketName: string;       // Bucket name for registry storage
+}
+
+// Example:
 storage: {
   accessKey: string;        // S3 access key
   accessSecret: string;     // S3 secret key
-  endpoint: string;         // S3 endpoint
+  endpoint: string;         // S3 endpoint (e.g., 's3.amazonaws.com')
   port?: number;            // Default: 443
   useSsl?: boolean;         // Default: true
-  region?: string;          // Default: 'us-east-1'
-  bucketName: string;       // Bucket name
+  region?: string;          // AWS region (e.g., 'us-east-1')
+  bucketName: string;       // Bucket name for this registry
 }
