First, I did not find where to post this issue, so I apologize if this is the wrong project for it.
In TypeRocket 6.1 (I use pro, but don't know if it matters), in the zip downloaded, the file typerocket/plugin/Updater.php is assigning a value to a new property $beta (line 43) which is not defined as a property of the class Updater. This causes a deprecation message to appear at the top of the website.
The fix is to simply define private $beta = false; after all the other properties in the Updater class.
