Bug fix
- CMS-46155 – Fixed an issue where editing a TestSection block in Edit view could cause one of its property values to revert to its initial state. This fix ensures that all property values retain their edits as expected.

- CMS-46191 – Fixed an issue where orphaned softlink references were not properly cleaned up from the tblContentSoftlink table when the associated content was deleted, leading to data integrity problems.
October 22, 2025
Enhancement
- Unified the error response format in the CMS API by aligning the Gateway's error responses with the CMS's Problem Details RFC format. This alignment excludes the oauth/token endpoint, which will continue to follow the OAuth standard per RFC 6749. Additionally, content negotiation with Accept: application/problem+json is recommended to ensure backward compatibility.
October 17, 2025
Enhancements

You can automatically translate content by selecting Translate content using AI and clicking Add Language. See Translate content automatically with AITranslate content automatically with AI for more information.
- Added functionality that lets content editors upload and select assets unique to each applicationapplication. When enabled, headless applications now generate unique URL segments to distinguish their assets, while in-process applications retain existing URLs.
- Enhanced search provider differentiation for Optimizely Graph and CMS.
- Improved logging and progress reporting for CMS content indexing to Optimizely Graph, providing clearer insights into job status, indexed document counts, skipped or failed items, and timestamps for each indexing step.

- CMS-45292 – Fixed the issue where internal links were incorrectly identified as external in TinyMCE under certain hostname configurations.
September 11, 2025
Enhancement
- Disabled the oauth token endpoint in the Integration API for SaaS preview3, since bearer tokens are now issued through the Gateway. This improves security and reduces redundancy. Customers do not need to take any action, and documentation remains unchanged.
- Moved the GraphiQL UIGraphiQL UI and Reset Account settings under Settings > Data & Sync Management for better visibility and easier navigation.
Bug fixes

August 25, 2025
Enhancement
- Added the ability to configure preview URLs in the Edit UIEdit UI. The preview now respects the URL configured for the content type being edited; falls back to the base type if needed, and uses the default route when no specific configuration exists. Editors are notified if the preview is disabled for the configured application.
- Updated the Synchronize with Optimizely Graph to sync directly, bypassing the queue and skipping hash validation, allowing immediate content updates with Optimizely Graph. Previously, it used the _stream endpoint, causing delays if the queue was long.
Bug fixes
- CMS-40562 – Fixed an issue where media in the 'For this page’ folder was not copied when you saved a section as a blueprint.
August 6, 2025
Enhancement

- CMS-43387 – Fixed an issue where the UI validation message for variation names incorrectly stated that dashes and dots were allowed, which caused confusion when the validation rejected those characters.
July 23, 2025
Enhancements
- Use Optimizely Mark chat (now generally available) to research, brainstorm, and edit content. See Get AI assistance with Optimizely Agent PlatformGet AI assistance with Optimizely Agent Platform.
- Made the DAM feature setting visible only for CMP indexing to ensure it does not appear to non-DAM customers.
- Included limited retries in the notification system for unsent messages, marking them as undelivered if retries are exhausted. You can track failed attempts and remaining retries with new fields in the notification table, ensuring unsent messages are managed efficiently by retrying at set intervals and logging failures.
Bug fixes
- CMS-41028 – Fixed an issue where copying and pasting unformatted text into a rich text editor would unexpectedly retain its original formatting, even when the paste option was set to unformatted.

July 3, 2025
Enhancements
- Embedded Digital Asset Management (DAM) in CMS to centralize asset management, streamline workflows, and ensure consistent branding, improving collaboration and efficiency while reducing costs. See Onboard DAM to CMS (SaaS)Onboard DAM to CMS (SaaS) and Manage assets with DAMManage assets with DAM.
- Introduced key enhancements to the Preview3 CMS API, improving usability, consistency, and maintainability. Important: Optimizely recommends updating API calls from Preview2 to Preview3 as early as possible so that customers are properly prepared for Preview2 support to be changed as we evolve the platform. See the following for a high-level list of updates to the Preview3 API:
- All Preview3 requests must now be authenticated through the API Gateway and are routed through https://api.cms.optimizely.com, removing the _cms prefix for unified access. See this article for more information: Authentication and AuthorizationAuthentication and Authorization
- Replaced all PUT endpoints with PATCH in the CMS Preview3 API for safer updates.
- Marked the Content and Changesets endpoints as experimentalexperimental to enable updates and feedback. Customers using the Content and Changeset endpoints in Preview2 should continue to use them in Preview3, but must be aware that breaking changes are possible.
- Added optimistic concurrency checks to ensure that there are no collisions between updates made through the API and updates made with the UX.
- Added new headers cms-skip-validation and cms-permanent-delete for Content endpoints, and cms-ignore-data-loss-warnings for PATCH content type.
- Updated headers for better consistency, such as opti-api-version to cms-api-version.
- Expanded datatype support, such as link and richText.
- Simplified enums into arrays of value objects for richer metadata and future-proofing.
- Applied ProblemDetails format for clearer, structured error responses.
- Updated so that keys are automatically assigned if not specified.
Example:
DELETE https://api.cms.optimizely.com/preview3/contenttypes/<key>
Authorization: Bearer <your_access_token>
Content-Type: application/json- Added the ability to create variations of a content item with its own publishing flow, so you can have multiple published variants of a content item at the same time. See Create content variations.Create content variations. You may want to create a content variation aimed at optimizing content performance and user engagement. For example:
- A/B testing – Content variations test different versions of a page or content element to determine which performs better in terms of user engagement, conversion rates, or other key metrics.
- Personalization – Variations enable personalized content delivery based on user segments, demographics, or behaviors, leading to a more tailored and relevant user experience.
- Localization – Use different content variations for different languages or cultural preferences, ensuring content resonates with a global audience.
- Seasonal campaigns – Variations let businesses adapt content for seasonal promotions or campaigns without altering the original content structure.
- Content optimization – By experimenting with different headlines, images, or calls-to-action, businesses can optimize content to improve SEO and user interaction.
- Flexibility in content management – Variations provide content managers with the flexibility to iterate and innovate quickly, responding to market trends or user feedback without disrupting the original content.
- Added a section type to help organize your content in an experience type in the Visual Builder. See Create content typesCreate content types.
- Added the ability to include a variation in the GraphQL queries (by adding a generic filter variation: {include: ALL}, or specify the variation key variation: {include: SOME, value: "WinterCampaign"}).
- Updated preview tokens to be reusable and more convenient to use. Previously, preview tokens were issued for specific content references. Instead of validating the preview token's content reference with the currently routed content reference, you can now validate the preview token principal's permissions to the routed content.
- Added the layoutType on the composition field of the graph format so that it is easier to understand the model. Example composition model where layoutType is added:
{
"_metadata": {
"key": "151A1E2E6358462FB3ABF0705FDCD03E",
"locale": "en",
"displayName": "My Experience"
},
