The update brings the build version number T875XXU1BUAC. The full update file size is above 2GB  so while downloading this make sure to use Wi-Fi to avoid data charges. The latest update adds One UI 3.0 features which bring improved UI, better usability, refined quick panel, and also the new features of Android 11. Unsurprisingly, Samsung also includes December 2020 security patch in the latest update. As of now, the company has not added all the changes in the update changelog.
As usual, the Galaxy Tab S7 LTE will get One UI 3.0 update in a phased manner. So, it may take some time to reach your phone. Alternatively, you can manually check for the update by navigating to Settings -> Software updates -> Check for updates.
