It appears the old site is https://softwareengineeringdaily.com/, and the new site ("in early beta") is https://softwaredaily.com/. The two sites appear to contain the same set of podcasts.

You can find an RSS feed at:

https://softwareengineeringdaily.com/feed/podcast

Somewhat confusingly, the new site has a navigation link, labeled "Feed", at the top of the page. But it's not an RSS feed. Rather, it leads to a compendium of links to interesting articles on software engineering from around the web. It looks like the plan is to implement voting for the articles (there is a vote count, but it's empty).
