# Version System

This project is using a SemVer-like version system.

I refer to version system formats that  
consists of separating differently numbered  
segments with dots as "catterpillar version systems".

SemVer-like then refers to a catterpillar  
version system with a length of 3 segments:

<h1>
  <img width="32px" height="32px" src="./Catterpillar Segment.svg"/>
  .
  <img width="32px" height="32px" src="./Catterpillar Segment.svg"/>
  .
  <img width="32px" height="32px" src="./Catterpillar Segment.svg"/>
</h1>

Version bumps are also categorised into  
different levels, such as major, minor and patch  
just like SemVer.  
However, there is a fourth category reserved  
for milestones in this version system.

The first segment (or head) of the  
version catterpillar corresponds to the milestone.

The second segment corresponds to the major.

The last segment (or tail) of the  
version catterpillar is shared by both  
the minor and the patch.
