Not sure which version, but you should be aware that version 10.5 goes out of support by Tableau in July, 2020. That will be here before you know it. Might I suggest installing a more modern up to date version like 2019.3? Many many updates have occurred since 9.3 including many security updates. Tableau's licensing engine, FlexNet (3rd party), was updated in 2019.3 to fix a security vulnerability. I'd recommend that version.
Not sure what you mean by: "Back button double click issue. ( Which is unable to control in a big dashboard which have 64 Sheet in it )"
It would take me days to go through every release version and read what was changed. I don't have that kind of free time.
You get a DEV, TEST, and PROD license so why not just download the latest version on a different VM or machine and try it out to see if it was changed? That would take a whole lot less time than searching back 5+ years of changes to the code.
