[Openstack][kolla] updates check

Hello, I am new user for openstack kolla because I installed openstack writing my ansible Playbooks. I wonder if it is a method to check if new images has been released . For example: I installed kolla wallaby 2 weeks ago, and now I want to check if new images could be updated. I want to check if new images solve some bugs. Is it possibile without trying to pull all images.? Thanks Ignazio
