1.6.27 includes some new features and improvements:

• (mfsrestore) fixed bug - freeing filenames memory too early
• (all) added initial support for extra attributes (xattr), which will be introduced in upcoming version 1.7
• (master+metalogger) better change log synchronization (storage in master memory and sending expected version in metalogger - inspired by Davies Liu)
• (master) acceptable difference of percent of hdd usage added to configuration (up to this version this parameter was constantly set to 0.01% - patch contributed by Davies Liu)
• (master) added emergency store metadata to some other places on errors during standard hourly store (inspired by Davies Liu)
• (cs) default space to be left (256MB) moved to config file (inspired by Davies Liu)
• (cs) added extra limits in mfshdd.cfg (minimum space to be left, maximum space to be used)
• (cs) fixed charts overflow issue (overflow in net transfer on about 575Mbps and hdd transfer on about 77MBps)
• (metalogger) fixed issue: file variable was not clear after close (on rare occasions might cause segfault after disconnecting from master)
• (all) cfg files moved form PREFIX/etc/ to PREFIX/etc/mfs/
• (cgiserv) improved CGI handle (added support for custom http responses, such as "302 Found")
• (master+cgi) showing disconnected chunkservers in "Servers" tab.
• (deb+rpm) mfscgiserv moved from mfscgi to separate package, changes in init scripts
• (mount) added option 'mfsdelayedinit' - for being run from fstab/init scripts
• (master) optimized goal management in chunks
• (master) fixed rare race-condition on clear/preserve cache during open in mount
• (mount) fixed compiling problems on Mac OS X
• (all) changed code to be more compatible with new gcc 4.7 (gcc 4.7 has too strong optimizations - it can generate unpredictable code)
• (master) sustain session time could be defined in mfsmaster.cfg
