# prepare-release.sh

#
|
||||
# Responsibilities:
|
||||
# - Validate tools
|
||||
# - Update CHANGELOG.md (move "Unreleased" -> new release section)
|
||||
# - Update README.md version references
|

# - Generate standalone release notes file
|

#
|

# What it does NOT do:
|

# - No Maven calls
|

# - No version bumping
|

# - No tagging
|

# - No Git commits

# Usage:

# scripts/prepare-release.sh <release-version>
|
