- (mount) Added password, file data cache, attribute cache and entry cache options. By default attribute cache and directory entry cache are enabled, file data cache and file entry cache are disabled.

- (mount) Added statistics accessible through MFSROOT/.stats pseudo-file.

- (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.
