Over four years ago, David Musgrave asked for a detailed RSS feed and I hacked one into WordPress (I was using the standard functionality for the summary RSS feed and it is one or the other).
It has taken me a while, but I have now created a proper detailed RSS feed by creating a plugin to provide this alternative feed (I will be releasing the plugin soon).
If you are using the current feed-full RSS feed, please change to using the new detailed RSS feed: https://www.azurecurve.co.uk/feed/detail
The current one will be available for a few more weeks, but I will then be retiring it.
