Unity Hub 3.21.1 Brings Small Workflow Improvements

Unity Hub 3.21.1 is a small but useful maintenance release focused on project management. The update adds custom project tags as quick-add suggestions in the Manage Tags dialog and improves long tag names by truncating them with an ellipsis while keeping the full value available on hover.

A small quality-of-life update

These changes are not headline engine features, but they make larger Unity project libraries easier to organize and scan. For developers managing many projects, cleaner tag handling can save time when navigating the Hub.
