# Project Name and Version
# starting from 2020: using semantic version number <major>.<minor>.<patch>
#   - bugfixes which do not change the API/ABI lead to an increase in <patch>
#   - backward-compatible API/ABI-changes mean an increasing <minor> version
#   - NON backward-compatible API/ABI-changes mean an increasing <major> version
# relation to older versioning scheme:
#   - v2015.10  <--> 1.0.0
#   - v2018.08  <--> 2.0.0
#   - v2019.11  <--> 3.x.y
#   ==> sematic versioning starts with 4.0.0
