Many have asked for new features documents from JMP version X-16. I pulled all the new features documentation docs and collected into a single PDF document. This goes back to JMP 5. If users are on versions before that, they are on their own.
These may be used to find out when a specific feature was added to the product. You can use the PDF search function and search for something like "reliability growth"
Notice how JMP 10 comes up first, which would mean the Reliability Grown platform was added in JMP 10.

Have fun!
