The version numbering is always built up using the same system:
X.Y[.Z][-preN]
X.Y[.Z]
Where
X is main version number
Y is release number
Z is patch number
N is pre-release number
One of these numbers will get bumped in each new release. The numbers to the
right of a bumped number will be reset to zero. If Z is zero, it may not be
included in the version number. The pre release number is only included in
pre releases (they're never used in public, official, releases).

The main version number will get bumped when *really* big, world colliding

performed. The patch number is bumped when the changes are mere bugfixes and

pre-release a certain release is.

It means that after release 1.2.3, we can release 2.0 if something really big
has been made, 1.3 if not that big changes were made or 1.2.4 if mostly bugs
were fixed. Before 1.2.4 is released, we might release a 1.2.4-pre1 release
