This prerelease is available for all platforms:

http://www.survex.com/

Full list of user-visible changes between 0.99-prerelease2 and
0.99-prerelease3:

* Documentation rearranged. Some sections which covered the same ground have
  been merged, and the documentation for each program is now available as a
  man page under Unix.

* (Unix version): Fixed problem with incomplete versions being specified in
  debian package dependencies.

Cheers,
Olly
