# The changelog check (2026-10-19): a commit that changes what users get
# adds a line under "## Unreleased" in CHANGELOG.md, so a release's notes
# are written as the work is done and versions say what changed.
#
#   scripts/changelog-check.sh [PATH...]
#
# PATHs are what the commit will take (as given to `oxy commit`); without
# any, the working copy's changes. Code is anything under src/, crates/,
# templates/, assets/, packaging/, images/ or scripts/, except tests.
# Docs, pipelines, pins (deps/) and lock files need no line. For a code
# change users won't notice (a refactor, a test helper), set NO_CHANGELOG=1.
