When looking at kernel version numbers installed in `/boot` using a work in progress command (`find /boot/vm* -printf "%A@ %p\n"`) I see:

```
1469098968.0000000000 /boot/vmlinuz-3.13.0-92-generic
1477523408.0000000000 /boot/vmlinuz-3.2.0-113-generic
1476549941.0000000000 /boot/vmlinuz-4.4.0-43-generic

1477145804.0000000000 /boot/vmlinuz-4.8.4-040804-generic

```

What are the proper names for "w.xx.y-zzz" that follows the `vmlinuz` prefix?

The proposed duplicate link ([What does the fourth number in the release version mean?](https://askubuntu.com/questions/637852/what-does-the-fourth-number-in-the-release-version-mean))states the second segment is called the `ABI Number`. The answer below by muru states the fourth segment is the `ABI Number` however I believe both are wrong based on the links provided in my own answer below.

Keep in mind this question is about ALL four segments w.x.yy-zzz and not just the fourth segment zzz.
