I really don't get the changes to podcasts in iTunes 11.
For some really stupid reason, I can set old video podcasts that are "in the cloud" as watched, but I cannot set old audio podcasts that are "in the cloud" as played.
I also found another annoying "feature" of podcast management since upgrading to iTunes 11.1.
I was happily riding to work this morning listening to my podcast playlist, when all of a sudden the podcast I was listening to just stopped playing. I didn't want to stop to find out what happened so just kept riding. When I got to work I discovered the podcast I was listening to had just vanished from my iPhone. My iPhone was secure in my pocket with the screen switched off so there is no way I could have accidentally pocket deleted it. I have never allowed the podcast app on my iPhone to manage my podcasts. I just use it to play my iTunes playlists.
Now that I am back at home I thought I would check iTunes and I have discovered that the podcast I was listening to has also disappeared from my iTunes library. I haven't synced my iPhone to iTunes for 3 days. This can be confirmed by looking at the last backup for the device in iTunes and the last sync time on the iPhone.
