# VERSION: 03.06.00
|
|
# BRIEF: Insert a versioned CHANGELOG.md entry immediately after the main Changelog heading
|
|
# Purpose:
|
|
# - Apply the MokoWaaS-Brand CHANGELOG template entry for a given version.
|
|
# - Insert a new header at the top of CHANGELOG.md, immediately after "# Changelog".
|
|
# - Avoid duplicates if an entry for the version already exists.
|
|
# - Preserve the rest of the file verbatim.
|
|
#
|
|
# Usage:
|
|
# ./scripts/update_changelog.sh <VERSION>
|
|
#
|
|
# Example:
|
|
# ./scripts/update_changelog.sh 01.05.00
|
|
