I am trying to learn Linux by creating a CTF as a hobby project, and I see that an enthusiast before me have been using Ubuntu server 16.04.4 (that i have been using to analyze and get ideas from) and i am only having Ubuntu server 16.04.7 available from my office desk. What does typically this last digit indicate?
And if you have time to explain the whole "release-tree"-structure to me i would be very grateful!
Thank you for for attention, Best regards, Tom
