  • (tools) mfssnapshot utility replaced by mfsappendchunks (direct descendant of old utility) and mfsmakesnapshot (which creates "real" recursive snapshots and behaves similar to "cp -r").
  • (tools) New mfsfilerepair utility, which allows partial recovery of file with some missing or broken chunks.
  • (cgi) First public version of CGI scripts allowing to monitor MFS installation from WWW browser.
