Release of FDS 5.5.2

A maintenance version of FDS has been posted to the Downloads page. This is version 5.5.2. Unless there are serious bugs to fix, this might be our last release of FDS 5. We are working on FDS 6, and those of you who participate in the group discussions will have already heard alot of chatter about FDS 6. One thing to keep in mind is that the transition from FDS 5 to 6 will be relatively transparent to most users. We are not planning on major changes to the input parameter names or file structure. The reason for changing from 5 to 6 is that there are going to be changes to the basic algorithm that warrent a change in major release number.

As always, for those of you who have submitted bug reports for FDS 5.5.1, please check that the new version fixes the problem if we have claimed to have fixed it. This is a very important part of our quality control, but unfortunately only about 1 in 10 users follow up on bug reports and actually verify that the fix has worked. Even worse, we often find out, months after fixing something, that the original submitter of the bug report continues to use the work-around that was suggested when the report was first submitted. That's not a good way to make progress.
