- upgrade to `yaml@1.0.0-rc.8` and `yaml-unist-parser@1.0.0-rc.4` - refactor some logic since the AST has slightly changed (ikatyang/yaml-unist-parser#82) - unmatched aliases are now errors since it may introduce invalid AST from `yaml` - rewrite the document separator (`...`/`---`) logic, this fixes some cases where it can use `---` but we printed `...` - removed some unnecessary duplicate trailing newline - trailing comments on `document` (`... #comment`) and `documentHead` (`--- #comment`) are preserved (i.e. they won't be moved somewhere)
