  • updated documentation
  • new and updated tests

v6.16

• mkfs:
  • print label of existing filesystem if attempting to overwrite
  • remove note about changed defaults in 6.15

• other:
  • cleanups and refactoring
  • sync sources with kernel
  • documentation updates
  • CI and test updates

v6.15

• other:
  • new and updated tests
  • documentation updates

v6.14

• mkfs:
  • allow --sectorsize to be 2K for testing purposes of subpage mode (needs the same block size supported by kernel)
  • fix false error when no compression is requested and lzo is not compiled in
• convert: support 2K block size in the source filesystem
• defrag: new parameter -L/--level to specify compression levels (kernel 6.15), also supports the realtime levels

• qgroup show: use sysfs to detect up to date consistency status
• zoned mode: support zone capacity tracking
• other:
  • CI new and updated workflows
  • documentation updates

v6.13

• mkfs:
  • new option to enable compression
  • updated summary (subvolumes, compression)
  • completely remove option --leafsize, deprecated long ago
• btrfstune: add option to remove squota
• scrub:
  • start: new option --limit to set the bandwidth limit for the duration of the run
  • status: fix printing of Rate unit suffix (SI/IEC)
• qgroup clean-stale: check if quotas are enabled before starting filesystem sync()
• print builtin features and options in --version output (mkfs, convert, image, btrfstune)
• build:
  • Botan minimum version is now 3.x
  • target to build compile_commands.json (for LSP)
• other:
  • a bit more optimized crc32c code
  • sync some headers from kernel code
  • command help updates and fixes
  • build warning fixes
  • error message updates
  • cleanups and refactoring
  • updated tests
  • lots of documentation updates

v6.12

• subvolume delete: add new option to do recursive subvolume deletion (for regular user delete only accessible subvolumes)
• mkfs:
  • new option --subvol to create subvolumes in given paths, read-write, read-only and default
  • add hard link detection support for --rootdir option
• fixes:
  • receive: message verbosity fixes
  • check: fix false positive report of missing checksum for extent holes
  • check: handle compressed extents when checking tree log
  • when asking Y/N user questions, flush the terminal so the question is displayed (e.g. btrfstune -S)
• other
  • code refactoring, error handling
  • python packaging fixes
  • documentation updates
  • new tests

v6.11

• check:
  • check items in tree-log
  • detect invalid file extent items for symlinks
  • properly detect inode cache and suggest removal by 'clear-ino-cache'
• convert: fix symlink length checks
• fi show: remove stray newline at the end of the output
