Is the lack of bin intentional?

~When there is no .changelog directory, the following code:~

It seems that current implementation expects that at least one major and at least one minor breaking change is found. When there is no items without major and minor breaking changes, the following code:

import { generateChangelog } from '@ckeditor/ckeditor5-dev-changelog';

generateChangelog( {
    cwd: process.cwd()
} );

throws an error:

� Listing the changes...
