Response from JoomlArt Updater Service: Sorry, this extension is invalid, unpublished or no longer supported: jak2tocomcontentmigrationplg_system_jak2tocomcontentmigration_j16
Is the error message obtained when checking if an updated version of the plugin is available. I am using 1.0.3, as provided in the download section, though the info charter mentions the current version should be 1.1.2.
Thanks for your feedback.
