change in the future
btrfs-progs-5.9 (2020-10-23)
----------------------------
* mkfs:
* switch default to single profile for multi-device filesystem, up to
now it was raid0 that may not be simple to convert to some other profile
as raid0 needs a workspace on all device for that
* new option -R for run-time options (eg. mount time enabled), now
understands free-space-tree
* subvolume delete:
* refuse to delete the default subvolume (kernel will not allow that but
the error reason is not obvious)
* warn on EPERM, eg. if send is on progress on the subvolume
* convert:
* fix 32bit overflows on large filesystems
* improved error handling and error messages
* check free space taking fragmentation into account
* check:
* detect and repair wrong inode generation
* minor improvement in error reporting on roots
* libbtrfsutils: follow main package versioning (5.9)
* add pkg-config file definitions
* python-btrfsutil: follow main package versioning (5.9)
* inspect tree-stats: print node counts for each level, fanout
* other:
* docs:
* remove obsolete mount options (alloc_start, subvolrootid)
* deleting default subvolume is not permitted
* updated or fixed tests
* .editorconfig updates
* move files to kernel-shared/
* CI:
* updated to use zstd 1.4.5
* fix reiserfs build
* more builds with asan, ubsan
* sb-mod updates
* build:
* print .so versions of libraries in configure summary
btrfs-progs-5.8 (skipped)
-------------------------
btrfs-progs-5.7 (2020-07-02)
----------------------------
* mkfs:
* new option to enable features otherwise enabled at runtime, now
implemented for quotas, 'mkfs.btrfs -R quota'
* fix space accounting for small image, DUP and --rootdir
* option -A removed
* check: detect ranges with overlapping csum items
* fi usage: report correct numbers when plain RAID56 profiles are used
* convert: ensure the data chunks size never exceed device size
* libbtrfsutil: update documentation regarding subvolume deletion
* build: support libkcapi as implementation backend for cryptographic
primitives
* core: global options for verbosity (-v, -q), subcommands -v or -q are
aliases and will continue to work but are considered deprecated,
current command output is preserved to keep scripts working
* other:
* block group code cleanups
* build warning fixes
* more files moved to kernel-shared
* btrfs-debugfs ported to python 3
* documentation updates
* new tests
btrfs-progs-5.6 (2020-04-05)
----------------------------
* inspect logical-resolve: support LOGICAL_INO_V2 as new option '-o',
helps advanced dedupe tools
* inspect: user larger buffer (64K) for results
* subvol delete: support deletion by id (requires kernel 5.7+)
* libbtrfsutil:
* support subvolume deletion by id
* bump version to 1.2
* library symbols are now versioned
* dump-tree: new option --hide-names, replace any names (file, directory,
subvolume, xattr) in the output with stubs
