In some edge cases, Checkmk lost some specific licenses:

  • Updating a site removed its license, even on a patch update such as 2.5.0p1 to 2.5.0p2. After the update the site was no longer licensed and started a new trial period, so you had to license it again.
  • In distributed monitoring with central setup, a remote site that you added after licensing the central site did not receive the license. It only got it with the central site's next license verification.

In both cases, Checkmk wrongly considered the license data of these licenses incomplete. Updates now keep these licenses, and new remote sites receive them right away.
