+- In the CLI, errors and warnings are now written to stderr. This allows you to
+  see issues that occur during `air format`, such as parse errors or file not
+  found errors (#155).
+
+- New global CLI option `--log-level` to control the log level. The default is
+  `warn` (#155).
+
+- New global CLI option `--no-color` to disable colored output (#155).
+
 - The default indent style has been changed to spaces. The default indent width
   has been changed to two. This more closely matches the overwhelming majority
   of existing R code.
