#
# FreeBSD Port Issue Body Generator for NetBird
#
# This script generates the issue body content for submitting a FreeBSD port update
# to the FreeBSD Bugzilla at https://bugs.freebsd.org/bugzilla/
#
# Usage: ./freebsd-port-issue-body.sh [old_version] [new_version]
# Example: ./freebsd-port-issue-body.sh 0.56.0 0.59.1
#
# If no versions are provided, the script will:
#   - Fetch OLD version from the FreeBSD ports GitHub mirror (current version in ports tree)
#   - Fetch NEW version from latest NetBird GitHub release tag
