btrfs-progs: add CHANGES 3.12 - 4.5.1
The changes are posted to the mailinglist and to the wiki, but for packaging reasons it's good to have them locally in the git as well. The initial conversion from wiki was done by Nick, then adjusted by me. Reported-by: Nicholas D Steeves <nsteeves@gmail.com> Signed-off-by: David Sterba <dsterba@suse.com>

+btrfs-progs-4.5.1 (2016-03-31)
+ * mkfs: allow DUP on multi-device filesystems
+ * bugfixes: build fixes, assorted other fixes
+
+btrfs-progs-4.5 (2016-03-20)
+ New/moved commands:
+ * btrfs-show-super -> btrfs inspect-internal dump-super
+ * btrfs-debug-tree -> btrfs inspect-internal dump-tree
+
+ New commands:
+ * btrfs fi du - calculate disk usage, including shared extents
+
+ Enhancements:
+ * device delete - delete by id (needs kernel support, not merged to
+ 4.6)
+ * check - new option to specify chunk root
+ * debug-tree/dump-tree - option -t understands human readable name of
+ the tree (along numerical ids)
+ * btrfs-debugfs - can dump block group information
+
+ Bugfixes:
+ * all commands should accept the option separator "--"
+ * several fixes in device scan
+ * restore works on filesystems with sectorsize > 4k
+ * debug-tree/dump-tree - print compression type as string
+ * subvol sync: fix crash, memory corruption
+ * argument parsing fixes: subvol get-default, qgroup create/destroy/
+ assign, inspect subvolid-resolve
+ * check for block device or regular file in several commands
+
+ Other:
+ * documentation updates
+ * manual pages for the moved tools now point to btrfs-filesystem
+ * testsuite updates
+
+btrfs-progs-4.4.1 (2016-02-26)
+ * find-root: don't skip the first chunk
+ * free-space-tree compat bits fix
+ * build: target symlinks
+ * documentation updates
+ * test updates
+
+btrfs-progs-4.4 (2016-01-18)
+ User visible changes:
+ * mkfs.btrfs --data dup
+
+ People asked about duplicating data on a single device for a long time. There
+ are no technical obstacles preventing that, so it got enabled with a warning
+ about potential dangers when the device will not do the duplicated copies. See
+ mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
+
+ * support balance filters added/enhanced in linux 4.4
+ * usage=min..max -- enhanced to take range
+ * stripes=min..max -- new, filter by stripes for raid0/10/5/6
+ * limit=min..max -- enhanced to take range
+ Note: due to backward compatibility, the range maximum for 'usage' is not
+ inclusive as for the others, to keep the same behaviour as usage=N .
+
+ * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
+ * error messages updates, rewordings -- some fstests may break due to that
+ * added support for free-space-tree implementation of space cache -- this
+ requires kernel 4.5 and is not recommended for non-developers yet
+ * btrfs filesystem usage works with mixed blockgroups
+
+ Other:
+ * installation to /usr/local -- this has unintentionally changed during
+ conversion to autotools in 3.19
+ * check: fix a false alert where extent record has wrong metadata flag
+ * improved stability on fuzzed/crafted images when reading sys array in
+ superblock
+ * build: the 'ar' tool is properly deteced during cross-compilation
+ * debug-tree: option -t understands ids for tree root and chnuk tree
+ * preparatory work for btrfs-convert rewrite
+ * sparse, gcc warning fixes
+ * more memory allocation failure handling
+ * cleanups
+ * more tests
+
+ Bugfixes:
+ * chunk recovery: fix floating point exception
+ * chunk recovery: endianity bugfix during rebuild
+ * mkfs with 64K pages and nodesize reported superblock checksum mismatch
+ * check: properly reset nlink of multi-linked file
+
+btrfs-progs-4.3.1 (2015-11-16)
+ * fixes
+ * device delete: recognize 'missing' again
+ * mkfs: long names are not trimmed when doing ssd check

+
+btrfs-progs-4.2.3 (2015-10-19)
+ * subvol sync: make it actually work again: it's been broken since 4.1.2,
+ due to a reversed condition it returned immediatelly instead of waiting
+ * scanning: do not scan already discovered filesystems (minor optimization)

+btrfs-progs-4.2.1 (2015-09-20)
+ * fix an off-by-one error in cross-stripe boundary check
+ * if nodesize was 64k, any metadata block was reported as crossing,
+ this leads to mkfs failure for example due to "no free blocks
+ found"
+ * for other nodesizes, if the end of the metadata block was 64k
+ aligned, it was incorrectly reported by fsck
+ * convert: don't write uninitialized data to image
+ * image:
+ * don't loop with option -t0

+ * other: minor cleanups
+
+btrfs-progs-4.2 (2015-09-03)

+ * find stripes crossing stripe boundary -- created by convert
+ * print correct range for file hole when there are no extents
+ and learn how to fix it
+ * replace: more sanity checks
+ * convert: concurrency fixes related to reporting progress
+ * find-root: option -a will not skip the current root anymore
+ * subvol list: fix occasional crash
