title: How can I get notified of updates to Python packages in a unified way?
body: <p>I work on a Python web application with 20+ dependency packages. I'd love to somehow get feeds of updates for all of these packages, so that I could look at their changelogs and update quickly if the package fixes important bugs or potential security vulnerabilities. Is there a way for me to do this without hunting down the project homepage RSS feed (if one exists) for all 20 packages individually?</p>
  
  <p>Ideally I'd like to be able to slurp our <code>requirements.txt</code> file and construct a feed automatically, but I'd settle for just manually curating a list of RSS feeds or manually subscribing some email address to a bunch of email lists.</p>
