Following the #5 update a large tent and barrel got cleaned up from one site but a barrel at another site persisted, so it was not the update to #5 that removed the tent.

The tent contained a large amount of damaged items in addition to good items in order to ensure that any thief left a pile of junk. No junk was left and the site was very remote and well hidden. I left a small tent there now but I expect cleanup will take it too.
