Podcast format/layout on my PC changed

Maybe I'm late to the party, but I connected my iPod to my computer for an update and the entire podcast section changed into this new layout on my PC. All old podcasts I had not listened to yet have disappeared with only the latest podcast showing. To get to the older podcasts, I have to go to the store, type in the podcast in search, click on the podcast and download from there, not the old way of right clicking the podcast and then click the "show in iTunes" which will take me right to the podcast. I can't find the "show in iTunes" any more. What's up with this layout change?
