Asteroid Framework showing in Joomla 4 Pre-Update

Hi, I am preparing a site for migration to Joomla 4, which is using Ultimate Template and Astroid Framework. When I run the Joomla 4 pre-update checker, Astroid Framework (library type) is listed in the "Update Information Unavailable" list. The version I am using is 2.5.4.
Can you tell me whether it is compatible with Joomla 4, I am guessing it is as the template is supposed to be compatible with Joomla 4. Maybe the item is showing as information unavailable in error?

Hello, please update to 2.5.5.
Anyway dont worry about the message, its compatible
