Dear MooseFS Users,

we would like to inform you about some changes that were made in MooseFS 2.0 (stable) recently:


MooseFS 2.0.83-1 (2016-01-08)
(mount) use direct I/O as a default mode on FreeBSD and Mac OS X (due to keep_cache bug in kernel/fuse)
MooseFS 2.0.82-1 (2015-11-06)
(all) fixed debug symbols
(master+supervisor) added metaid check (pro version only)
(master) added rejection of followers with incorrect meta version (pro version only)
(mount) added new mechanism for sustaining working directories (replaces mechanism added in 2.0.74)
(mount) create in deleted directory returns EACCES only in OS X (ENOENT in other systems)
(cli) fixed show exports in plain mode
(master) added sending metaid after switching from ELECT to LEADER (pro version only)
(master) removed option '-e' from GPL edition (only makes sense in pro version)
(master+cs) added sending metaid to cs in ELECT state (pro version only)
(master) improved metaid generation method
(all) improved reloading cfg files (commented out options should be treated the same as options set to default values)
