 # Changelog
 
+## [1.9.1](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.9.1)
+
+- fix: security updates
+
 ## [1.9.0](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.9.0)
+
 - Feat: Variant utilities `getVariantAliases` and `getVariantMetadataTags` to read variant alias strings from CDA entry `publish_details.variants` (requires fetches with the `x-cs-variant-uid` header set to aliases per [CDA variants](https://www.contentstack.com/docs/developers/apis/content-delivery-api#get-all-entry-variants)).
 
 ## [1.8.0](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.8.0)
+
 - Fix: JSON-to-HTML now outputs valid HTML for nested lists when JSON RTE exports the nested list as a sibling of the preceding list item (`<li>`). The SDK folds such sibling `<ol>`/`<ul>` nodes into the previous `<li>` so the rendered HTML has the nested list inside the parent list item (PROD-2115).
 
 ## [1.7.1](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.7.1)
+
 - Fix: Guard against null/undefined in getTag to prevent TypeError when addEditableTags/addTags processes entries with null content (Issue #193)
 
 ## [1.7.0](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.7.0)
+

 ## [1.6.3](https://github.com/contentstack/contentstack-utils-javascript/tree/v1.6.3)
- - Refactor: Simplified endpoints.ts to use compile-time JSON import instead of runtime file loading
- - Build: Updated build process to download regions.json to src/assets directory
- - Test: Added comprehensive test coverage for endpoints.ts
- - Chore: Removed postinstall/postupdate scripts and simplified package.json scripts
