# According to http://www.gnu.org/software/libtool/manual/libtool.html#Updating-version-info :
#
# 1) when bugs are fixed or internal code is changed: increase MICRO
# 2) if API is added, increase MINOR and set MICRO to 0
# 3) if API or ABI is broken (this case should (must) never happen as it's very bad for a library), or a new designed library, increase MAJOR and set MINOR and MICRO to 0
