Will files and saves from v 1.3 work with 1.5?

I just found out I have version 1.3. I thought I had 1.5. I am working on the traits and retinues for the files for ITW, so are the files compatable?

Come on people, I really need to know...

The ancs. and traits files in 1.3 and 1.5 are different dates and the
export_descr_character_traits.txt in 1.5 appears to be 2kb larger so there are probably some differences. Although using old ones might not cause crash - I don't think the general system changed - but even if not, you could end up losing some of the refinements / fixes made for the 1.5 patch. I think you can get programs that will compare the content of text files, trying to find one of them and comparing the vanilla versions for each patch might help you decide if you can use your files or not.

Saves; I can't remember if it was save game compatible - might say somewhere in the download info for the patch.

Thanks
