# Always use 0.xx+devel instead of 0.xxdevel for the version, e.g. 0.46+devel.
# Rationale: (i) placate simple version comparison software such as
# `dpkg --compare-versions'.  (ii) We don't always know what the next
# version is going to be called until about the time we release it
# (whereas we always know what the previous version was called).
