**Version:** v5.18.0

**Published:** March 24, 2026

This release fixes critical issues with authentication persistence in Next.js, session management errors, and the `@mention` dropdown functionality, while also improving performance by reducing unnecessary API requests.

## 🐛 Notable bugfixes and improvements

- Restores the behavior where asset sources receive the current asset in `selectedAssets` when opened via the browse flow, even when the field already has a value.
- Fixes an issue causing authentication to not persist between page reloads in Next.js.
- Fixes an issue where the `@mention` dropdown in comments might show “*No users found”* when any `system.group` document had `members: null`.
- Fixes virtualization issues using the dialog and `renderDefault`.
