CHLU stands for CHange Log Update.
Before lerna, before monorepos, around 2017, we used to write changelogs manually and this was an API for a helper CLI (chlu-cli) which automated some changelog content areas.
Our tooling has advanced greatly since then. Nowadays we generate changelogs automatically, using lerna and commitizen and we have a tool to clean those changelogs, lerna-clean-changelogs-cli.
