We've released the documentation set for Satellite 5.7. There have been a number of documentation changes since Satellite 5.6 that I want to highlight.
Firstly, there is new content for a bunch of new features. I've included a high-level list in the Release Notes for 5.7.
I'm also looking to improve our Satellite 5.7 documentation suite over time so please feel free to let me know if you've got any suggestions for improvements or if you hit any roadblocks while following certain procedures.
