    A Coco program with a node-locked license now expects that the license had been generated on the same account as that one under which it runs.

    Previously, the account to which a license was bound was that one under which the user that started it had initially logged in. Changing the account with su or sudo had no influence on the license. This means that under some circumstances a license was generated for an account different from that under which Coco ran, but it worked nevertheless. In these cases, the license must now be renewed.
