No real need except for security fixes. I bet a WordPerfect version from 20 years ago would be good enough for most. I was just wondering if there was a specific reason.
Security fixes, on an application that is not used "online" in any way, and only used internally on user created documents?
Yea, not worried there mate. But no, will pass on Word Perfect, was a WordStar user myself. And "security flaws" for such programs was more along the lines of scripts embedded in documents than anything else. Once again, not an issue since I create all documents used in it.
And I am doubly safe, as I do not even save in the higher level formats. I specifically save all my documents in a very old format, where that is not an issue. However, I do so mostly out of a desire to be able to port them to a large number of programs, not any kind of security mania.
