A quick post to highlight a minor change to the PWA web parts in 2013. I was in the process of creating a new PDP on a 2013 environment and I wanted to add certain custom fields. In 2010 the web part that enabled you to do this was the Project Fields web part:
In 2013 this web part doesn’t exist, well it does but it is no longer called Project Fields, it is now called Basic Info:
It provides exactly the same functionality as the Project Fields web part in 2010.
Hopefully that will save you hunting around for this web part
