 * Explanation:
 *  - log commits                                               | git log
 *  - limit log output to a single line per commit              | --oneline
 *  - looks only at the most recent commit                      | -1
 *  - silent grep output                                        | grep -q
 *  - exits with code 0 if a match is found                     | grep -q "chore(release):"
 *  - exits with code 1 if a match is found (reverse-match)     | grep -qv "chore(release):"
