name: release

# Cross-builds Wownero release binaries via contrib/depends and attaches them to
# a GitHub Release. Asset names match the established convention from past releases:
#   wownero-<host-triplet>-<version>.{tar.bz2,zip}
#
# Runs on the GitHub mirror's hosted runners. Triggers:
#   * pushing a version tag (v*)       -> builds + publishes a Release for that tag
#   * manual dispatch (workflow_dispatch):
#       - ref:     tag/branch/commit to build (e.g. v0.11.4.0); blank = default branch
#       - publish: if true, attach the built assets to the Release for `ref`
#                  (use this to add binaries to an already-tagged release)
