Unity Hub 2.4.5 Page

Verdict: For users on Unity 2020.3 LTS or older, 2.4.5 is the gold standard. For Unity 2022.3+ or new projects, you may be forced to upgrade, but 2.4.5 remains excellent for legacy maintenance.

Unity Hub 2.4.5 is a mature, stable release suitable for developers who prioritize reliability over newer interface features. It handles core tasks—Editor installation, project management, and license activation—without significant issues.

For most users in 2025+, upgrading to a newer Hub version (2.5.x or later) is recommended to access updated features and long-term support, but 2.4.5 remains a solid fallback for legacy workflows or systems where UI changes are undesired.
