[Koha] Which version manual should I check

Hi, I am beginning to learn Koha for our library. The version of Koha that was installed on our server is: 3.14.09.001 Should I check the manual for Koha 3.14? Or is there a 3.14.0 manual? Is it very outdated? Apologies for the silly questions. Thank you, it's great to be part of a group, where I can even post these doubts! Take care! Regards, Ahalya --
