Workspace audit logs and improvements for Webflow Apps

Introducing workspace audit logs
To enable better security and compliance monitoring, the Webflow Data API now supports workspace-level audit logs for enterprise customers. In combination with the existing site-level audit logs, teams now have a complete view of user activity across their organization.
Use the Workspace Audit Log API to track important user events, including:
- Login activity
- Custom role events
- Workspace membership events
- Site membership events
- Workspace invitations
This endpoint requires authentication with a Workspace API token

Inviting users to test apps

Safeguarding app settings for marketplace apps
We’ve improved stability for marketplace apps by implementing safeguards against breaking changes. To protect both app developers and end users, certain critical setting changes for published apps now require re-approval through our update process. This ensures your users always have a consistent experience while giving you a controlled path to evolve your app’s capabilities. In your app settings modal, you’ll now see some disabled settings that require re-approval to make changes.These settings include:
- Adding a new building block (Designer or Data API)
- Changing app scopes
Support for combo classes
The Designer API now supports the creation of combo classes. Combo classes are a way to override the styles of an existing parent class. This is useful for creating unique variations of a style without having to create an entirely new class.
In the Designer API, you can now create combo classes using the createStyle method and passing an existing style to the parent property. For example, if you have a parent class called button and you want to create a new style that applies a different color for a specific button, you can do the following:
