Version number is A.B.C.D where :
A is the main version number, it changed from 1 to 2 when I reworked the whole interface
B is the version number, when I add a new feature this number changes
C is the subversion number, no new feature was added in this release just bugfixes.
D represents the windev framework used to compile, for exemple 4 stands for 01F240063m
