# Here's the (hopefully simple) versioning scheme.
#
# Releases of notmuch have a two-digit version (0.1, 0.2, etc.). We
# increment the second digit for each release and increment the first
# digit when we reach particularly major milestones of usability.
#
# Between releases, (such as when compiling notmuch from the git
# repository), we add a third digit, (0.1.1, 0.1.2, etc.), and
# increment it occasionally, (such as after a big batch of commits are
# merged.
