This release will be available starting October 24 and affects several themes.
IMPORTANT: This release is only available for Office 365 and SharePoint 2019 Modern experience.
Improvements
We've significantly improved the performance when loading navigation items. You should now experience quicker and more responsive navigation.
Fixes
We've fixed an issue where navigation items would disappear when resizing the window, particularly when the ellipsis option was active. All navigation items will now remain visible and accessible, regardless of screen size.
