+
+## Migration Guide
+
+### For Existing Applications
+
+No immediate action required. The upgrade is transparent to existing applications.
+
+### To Adopt New Features
+
+#### 1. Batch Operations
+
+```typescript
+import { BatchOperationType } from '@objectstack/spec/api';
+
+// Example: Batch create records
+const result = await api.batch({
+  type: BatchOperationType.CREATE,
+  object: 'users',
+  records: [
+    { data: { name: 'User 1', email: 'user1@example.com' } },
+    { data: { name: 'User 2', email: 'user2@example.com' } }
+  ],
+  options: {
+    atomic: true, // All-or-none transaction
+    returnRecords: true
+  }
+});
+```
+
+#### 2. Standardized Error Codes
+
+```typescript
+import { StandardErrorCode, ErrorCategory } from '@objectstack/spec/api';
+
+// Example: Handle errors with standard codes
+try {
+  await api.update(record);
+} catch (error) {
+  if (error.code === StandardErrorCode.CONCURRENT_MODIFICATION) {
+    // Handle concurrent modification
+  } else if (error.category === ErrorCategory.VALIDATION) {
+    // Handle validation errors
+  }
+}
+```
+
+## Technical Notes
+
+### Why the Patch?
+
+The @objectstack/objectql@0.7.1 package publishes with `"main": "src/index.ts"` which points to uncompiled TypeScript source. This causes issues when:
+
+1. TypeScript tries to compile it with different module resolution settings
+2. Runtime expects compiled JavaScript
+
+The patch changes:
+```json
+{
+  "main": "src/index.ts",    // Before
+  "types": "src/index.ts"
+}
+```
+
+To:
+```json
+{
+  "main": "dist/index.js",    // After
+  "types": "dist/index.d.ts"
+}
+```
+
+This is a temporary workaround until the upstream package is fixed.
+
+### ES Modules Support
+
+Version 0.7.1 includes proper `.js` extensions in ES module imports, fixing issues that required patching in 0.6.1. The @objectstack/runtime package now properly supports both CommonJS (for NestJS) and ES modules.
+
+## Next Steps
+
+### Immediate
+- ✅ Upgrade complete
+- ✅ All tests passing
+- ✅ All builds successful
+
+### Optional (When Ready)
+- Adopt batch operations for bulk data processing
+- Implement standardized error codes in API responses
+- Explore new AI protocol features
+- Add GraphQL support if needed
