# End users see version strings like this:
# "1.0.0"
# ^ ^ ^
# | | |
# | | '- micro version number
# | '- minor version number
# '- major version number
# The first number is "major version number". The second number is the "minor
# version number" -- it gets bumped whenever we make a new release that adds or
# changes functionality. The third version is the "micro version number" -- it
# gets bumped whenever we make a new release that doesn't add or change
# functionality, but just fixes bugs (including performance issues).
# Early-adopter end users see version strings like this:
# "1.0.0a1"
# ^ ^ ^^^
# | | |||
# | | ||'- release number
# | | |'- a=alpha, b=beta, c=release candidate, or none
# | | '- micro version number
# | '- minor version number
# '- major version number
# The optional "a" or "b" stands for "alpha release" or "beta release"
# respectively. The number after "a" or "b" gets bumped every time we
# make a new alpha or beta release. This has the same form and the same
# meaning as version numbers of releases of Python.
# Developers see "full version strings", like this:
# "1.0.0a1-55"
# ^ ^ ^^^ ^
# | | ||| |
# | | ||| '- nano version number
# | | ||'- release number
# | | |'- a=alpha, b=beta, c=release candidate or none
# | | '- micro version number
# | '- minor version number
# '- major version number
# or else like this:
# "1.0.0a1-r22155"
# ^ ^ ^^^ ^
# | | ||| |
# | | ||| '- revision number
# | | ||'- release number
# | | |'- a=alpha, b=beta, c=release candidate or none
# | | '- micro version number
# | '- minor version number
# '- major version number
# The presence of the nano version number means that this is a development
# version. There are no guarantees about compatibility, etc. This version is
# considered to be more recent than the version without this field
# (e.g. "1.0.0a1").
# The nano version number or revision number is meaningful only to developers.
# It gets generated automatically from darcs revision control history by
# "darcsver.py". The nano version number is the count of patches that have been
# applied since the last version number tag was applied. The revision number is
# the count of all patches that have been applied in the history.
