If you mean can you build an RSS feed with earlier (V 1.24) versions of Coranto - YES.
The techniques discussed in this thread work fine with Coranto 1.24. To rename the file with the proper extension you can use the Post-Build File Renamer/Mover addon. Discusion thread
You can also use the Feed Builder addon if you don't want to build your own profile/style/template. Discussion here.
