+
+There is now a new configuration option `indent_mode`. This can be set to `"auto"`, `"spaces"` or
+`"tabs"`. Setting it to `"auto"` will enable detection of the indentation mode on a per buffer
+basis. The detection is fairly simple and enables tab indentation if a line starting with a tab
+character is found anywhere in the file.
