We are testing a project that got upgraded from an ancient 6.5 version to 8.1. We noticed that events related to publishing certain items got fired without any reason (well, not that we can see). The logs do mention publishes, so the event is right: somehow the publish does get triggered.
But we have no clue why.. we certainly did not perform a manual publish. We do have some automated processes but not on those items. And it doesn't happen on the old version. Any idea why since the upgrade items get published without anyone actually publishing them?
