+## Migrating from v3 to v4
+
+This changelog documents a breaking change to the `ISystemFields` interface, specifically related to the `publish_details` field.
+
+## What Changed
+
+The `publish_details` field is no longer an array of objects. It is now represented as a single `IPublishDetails` object.
+
+This update aligns the generated types with the actual [Contentstack API](https://www.contentstack.com/docs/developers/apis/content-delivery-api) response.
+
+## Before
+
+```typescript
+export interface ISystemFields {
+  uid?: string;
+  created_at?: string;
+  updated_at?: string;
+  created_by?: string;
+  updated_by?: string;
+  _content_type_uid?: string;
+  tags?: string[];
+  ACL?: any[];
+  _version?: number;
+  _in_progress?: boolean;
+  locale?: string;
+  publish_details?: IPublishDetails[]; // Incorrect: Array of IPublishDetails
+  title?: string;
+}
+```
+
+## After
+
+```typescript
+export interface ISystemFields {
+  uid?: string;
+  created_at?: string;
+  updated_at?: string;
+  created_by?: string;
+  updated_by?: string;
+  _content_type_uid?: string;
+  tags?: string[];
+  ACL?: any[];
+  _version?: number;
+  _in_progress?: boolean;
+  locale?: string;
+  publish_details?: IPublishDetails; // Corrected: Single IPublishDetails object
+  title?: string;
+}
+```

 ## Migrating from v2 to v3
+
 This document outlines the necessary changes to separate nested modular blocks into distinct interfaces. This update will affect how modular blocks are structured and used throughout the codebase.
