At the Feed/iTunes Settings page is a new section which is called podPress Feeds. This new section contains the settings to control the meta data of the podcast feed. There you can modify the feed title, the author name and the summary as well. These settings have been the same for all feeds. But now they are separated and you have the possibility to vary these settings for the additional feeds like the one with name podcast.
Your observation that during the upgrade some values have not been taken over is right. But it should definitely be possible adjust these values.
Have you upgraded from 184.108.40.206 to 220.127.116.11 directly?
The podPress versions 18.104.22.168 - 22.214.171.124 have no appropriate mechanism which takes over the old settings automatically. If you have upgraded to one of these versions first then you need to adjust all these feed meta information settings manually. Please, take a closer look at the podPress Feeds section.
I'm sorry that your upgrade went not smooth and that there were not more helping notices during or after the upgrade and that there were not enough automatism. I will be more carefully with new feature in future versions.
