# RELEASING

# Version numbering. See also VERSION and Version.hs.
#
# hledger's version number appears in:
#  hledger --version
#  hledger's cabal file
#  darcs tags
#  hackage tarball filenames
#  hackage pages
#
# Some old version numbering goals:
# 1 automation, robustness, simplicity, platform independence
# 2 cabal versions must be all-numeric
# 3 release versions can be concise (without extra .0's)
# 4 releases should have a corresponding darcs tag
# 5 development builds should have a precise version appearing in --version
# 6 development builds should generate cabal packages with non-confusing versions
# 7 there should be a way to mark builds/releases as alpha or beta
# 8 it should be easy to darcs get the .0 release even after bugfix releases
# 9 avoid unnecessary compiling and linking
# 10 minimise rcs noise and syncing issues (commits, unrecorded changes)
#
# Current policy:
#
# - We follow http://haskell.org/haskellwiki/Package_versioning_policy
#
# - The full release version is ma.jor.minor, where minor is 0 for a
#   normal release or 1..n for bugfix releases.
#
# - The elided release version is ma.jor when minor is 0. We use it for
#   hackage releases when possible, trusting it doesn't cause trouble..
#
# - The build version is ma.jor.minor+patches, where patches is the number
#   of patches applied in the current repo since the last release tag.
#
# - The release tag in the repo is the full release version.
#
# - hledger --version shows the release version or build version as
#   appropriate.
#
# - The VERSION file must be updated manually before a release.
#
# - "make simplebench" depends on version numbers in BENCHEXES, these also
#   must be updated manually.
#
# - "make" updates the version in most other places, and defines PATCHES.
#   Note "cabal build" should also do this but doesn't yet.
#
# - "make release" additionally records the main version number-affected
#   files, and tags the repo with the release tag.

# Build a release, tag the repo, prepare a cabal package
# Don't forget to update VERSION first. Examples:
# normal release:   echo 0.7   >VERSION; make release
# a bugfix release: echo 0.7.1 >VERSION; make release
