# Build the GitHub-release body from the CHANGELOG — generated, never hand-written, so the changelog
|

# stays the single source.

# Every bullet is `- **one-line effect.** then the rationale` (docs/releasing.md): the bold lead is
|
|
# what a release reader wants, the rationale is for maintainers. So the notes are those leads,
|
|
# grouped under their `###` headers — which means a bullet with NO bold lead is silently omitted,
|
|
# and an empty section prints no header.
|
|
#
|
|
# CHANGELOG.md is primary; the CHANGELOG_ru.md mirror's summary is appended under a divider.
|
|
#
|
|
# Usage: release-notes.sh <version> [changelog-file], version without the leading v.
|
|
# Prints to stdout. Pure sh and awk, so the release job needs no node.
