A few minutes are up to publish the stable versions of Pentaho BI Server 3.5.2.
You can download it at: https://sourceforge.net/projects/pentaho/files/
I have not reviewed this version, but I am doing beta testing before and have found no major changes in the UI, just some updates of bookstores, but not widen too much.
Whenever I get more information, I have the relevant comments.
Greetings
