Ok....
Here is the update. THE UPDATE IS NOT NULLED.
I was able to get the zip file in the update in a diff manner by nulling some lines.
Make sure you make a full backup of your site prior to updating.
The tracker.js file was pretty much all that was updated. But better to null the entire.

userTrack 3.4.4 (17 March 2021)
Added bot filtering, some improvements for the WordPress version, new translations and some fixes.
This update includes changes to tracker.js.
ust.min.js will be updated so make sure to clear all relevant caches so users load the latest tracker file.
Updating the tracker include code, which already contains a cache-breaker is the best way to clear the cache. (eg. ust.min.js?v=3.4.4)
