* MooseFS 1.6.0 (not released - only available in public repository)

 Common:

 - Removed duplicate source files.

 - Strip whitespace at the end of configuration file lines.

 Chunkserver:

 - Rewritten in multi-threaded model.

 - Added periodical chunk testing functionality (HDD_TEST_FREQ option).

 - New -v option (prints version and exits).

 Master:

 - Added "noowner" objects flag (causes objects to belong to current

user).

 - Maintaining `mfsdirinfo` data online, so it doesn't need to be

calculated

   on every request.

 - Filesystem access authorization system (NFS-like mfsexports.cfg file,

   REJECT_OLD_CLIENTS option) with ro/rw, password and maproot

   functionality.

 Mount:

 - Rewritten options parsing in mount-like way, making possible to use

   standard FUSE mount utilities (see mfsmount(8) manual for new syntax).

   Note: old syntax is no longer accepted and mountpoint is mandatory now

   (there is no default).

 - Updated for FUSE 2.6+.

 - 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.

 - opendir() no longer reads directory contents - it's done on first

   readdir() now; fixes "rm -r" on recent Linux/glibc/coreutils combo.

 - Fixed mtime setting just before close() (by flushing file on mtime

   change); fixes mtime preserving on "cp -p".

 - Added statistics accessible through MFSROOT/.stats pseudo-file.

 - Changed master access method for mfstools (direct .master pseudo-file

   replaced by .masterinfo redirection); fixes possible mfstools race

   condition and allows to use mfstools on read-only filesystem.

 Tools:

 - Units cleanup in values display (exact values, IEC-60027/binary

prefixes,

   SI/decimal prefixes); new options: -n, -h, -H and MFSHRFORMAT

environment

   variable - refer to mfstools(8) manual for details).

 - mfsrgetgoal, mfsrsetgoal, mfsrgettrashtime, mfsrsettrashtime have been

   deprecated in favour of new "-r" option for mfsgetgoal, mfssetgoal,

   mfsgettrashtime, mfssettrashtime tools.

 - mfssnapshot utility replaced by mfsappendchunks (direct descendant of

   old utility) and mfsmakesnapshot (which creates "real" recursive

   snapshots and behaves similar to "cp -r").

 - New mfsfilerepair utility, which allows partial recovery of file with

   some missing or broken chunks.

 CGI scripts:

 - First public version of CGI scripts allowing to monitor MFS

installation

   from WWW browser.

Kind regards
