I am using version 4.2 and have been for some time. I am wondering what benefit there would be to getting 8.0 or 8.5, if any. I LOVE the version I have now. Would all my family files trnasfer over to a newer version? Also, does anyone know of any limitations that the older versions have such as maximum number of names per file or max number of references, or file size? Any help is greatl appreciated.
