As you probably know, in addition to the new great features the version 16.2 introduced, there are also various improvements to the learning materials that will allow you get the most of DevExpress products and become a better developer. The XAF documentation changes are listed below. I highlighted the topics I personally like or value the most in yellow. I would also greatly appreciate it, if you tell me about your favorite topics in comments!
The good news is that there are even more documentation updates currently in the works, and hopefully, I will be able to announce them to you soon.
Concepts and task-based help
As you can see, there are both totally new articles and updates to the existing ones. Hopefully, even people familiar with the framework will find something helpful here. As always, the full list of What's New In Help for all products is waiting you here.
General upgrade tips
Please do not miss the new Breaking Changes in 16.2.3 .NET Product Line app allowing you to see a list of changes from version X to version Y (btw, there must be no BCs for XAF in v16.2). This information will help you upgrade your project to the new major version faster. See the General Information > Installation > Upgrade Notes documentation article for step-by-step upgrade instructions. You can find more upgrade tips in the end of my related blog post.
