158 User visible changes:
159 * mkfs.btrfs --data dup
161 People asked about duplicating data on a single device for a long time. There
162 are no technical obstacles preventing that, so it got enabled with a warning
163 about potential dangers when the device will not do the duplicated copies. See
164 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
166 * support balance filters added/enhanced in linux 4.4
167 * usage=min..max -- enhanced to take range
168 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
169 * limit=min..max -- enhanced to take range
170 Note: due to backward compatibility, the range maximum for 'usage' is not
171 inclusive as for the others, to keep the same behaviour as usage=N .
173 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
174 * error messages updates, rewordings -- some fstests may break due to that
175 * added support for free-space-tree implementation of space cache -- this
176 requires kernel 4.5 and is not recommended for non-developers yet
