# Glade uses a Major.Minor.Micro versioning system
#
# With odd minor numbers representing development releases and even numbers
# stable releases and micro numbers bug bugfixes.
#
# Since master is built as a nightly flatpak, we bump the version to development
# inmediatelly after making a stable release, that way people using the nigthly
# version will always know they are on a development release.
