Your RDM is updated-message

Hello. Our users are complaining about a "Your RDM is outdated" message on the "getting started" dashboard.
We upgraded to 2026.2.11.0 before we went on summer vacation and newest version now is 2026.2.17.0. That's not a huge difference? Has something changed in the release model, how long can we expect a version to be considered supported?
Also is there a registry key to disable the page, I cannot find one here: Apply policies (GPOs) | Devolutions RDM | Product guides & reference
