You can always check the latest version on unstoppable github release page, and 0.41.3 was the last one released:

People seem reluctant to open Unstoppable github to check the latest unstoppable wallet release because they can get notifications through the mobile used. For example Android users.
Not for all I addressed this because there are also some of the users who pay attention to the release of the latest version of Unstoppable Wallet from Github Unstoppable.
Version 0.41.3 was released 3 weeks ago and not many things were updated, only Fixed Transaction Sync for Litecoin. Maybe the latest release of Unstoppable Wallet in the future is also the same that is not many items are updated.
