 #### Differences from previous versions
 
 Note that if you used versions below `0.4.0` of this gem, the naming and contents of the split files have changed. Split files no longer need to have the `.split2` extension and now use the `require` directive rather than the `include` directive. The previous prohibition against using `require_tree .` and `require_self` directives also no longer applies.  For more details see the [CHANGELOG.md](CHANGELOG.md#040)
 
+#### Empty *_split2.css file
+
+Since 0.4.1 in development split stylesheets have `debug: false` option by default. This prevents the empty `*_split2.css` file issue. You can always explicitly go one way or the other setting `debug` option directly in the `split_stylesheet_link_tag` like this:
+
+```
+<%= split_stylesheet_link_tag "application", debug: false %>
+```
