The current stable release is 1.4.1.
Note: Newer Scribus version can open the older version's file, but the opposite is not true. Scribus 220.127.116.11 cannot open Scribus 1.4.x files. There is no way to convert the file back once you switch it to the newer branch. However, you can run both branches in parallel to test the new functionality.
Current stable version is 18.104.22.168. It is not maintained anymore. This is the last 1.3.3.x series version. Use it only if you have a specific reason not to use 1.4.1.
This is where the exciting new features of Scribus are going. However, there could be many stability problems due to frequent changes, so you are only advised to use this version for small very specific tasks and for keeping abreast of the Scribus development, but not for day-to-day production work.
