ok, is there any reason not to use 1.4? The interface is much better.

Here is the reason:

1.3.2 uses the default sync manager size, instead of sum of the mapped
PDO entries. A quick solution would be to write a '4' to the SII. But,
if there aren't any reasons against this, please use the 1.4 release.
