In this page, I'll explain what does the 4 (sometimes 5) different numbers for my site's version number mean.
1st number: A.B.C.D
This is the major version number. This indicates that there's an ultimate overhaul to my site, with a completely different design, or if the website hyper-expanded quickly.
2nd number: A.B.C.D
This is the massive version number. This indicates that there are some big changes in the site, such as a creation of a new page.
3rd number: A.B.C.D
This is the minor version number. This indicates that some parts of the site is updates, or maybe removed for a valid reason.
4th number: A.B.C.D
This is the small version number. This indicates that something like a bug in the site is fixed that is obvious.
5th number: A.B.C.D.E
This is the beta version number. It only shows up in betas. This indicates that something is updated in the beta version of the site.
Letter after the version numbers: A.B.C.D (e)
This indicates that there's a status update in the site.
Please note that very minor updates will not increase any number in the website version.
