Version 1.5.1

• Added a warning to -mount, since it will change behaviour in the next POSIX revision
• Added a workaround for environments that block statx() with seccomp(), like older Docker
• Fixed coloring of nonexistent leading directories
• Avoided calling stat() on all mount points at startup

Version 1.5

• New -xattr predicate to find files with extended attributes
• Fixed the -acl implementation on macOS
• Implemented depth-first (-S dfs) and iterative deepening search (-S ids)
• Piped -help output into $PAGER by default
• Fixed crashes on some invalid LS_COLORS values

Version 1.4.1

• Added a nicer error message when the tests are run as root
• Fixed detection of comparison expressions with signs, to match GNU find for things like -uid ++10
• Added support for https://no-color.org/
• Decreased the number of stat() calls necessary in some cases

Version 1.4

• New -unique option that filters out duplicate files (#40)
• Optimized the file coloring implementation
• Fixed the coloring implementation to match GNU ls more closely in many corner cases
  • Implemented escape sequence parsing for LS_COLORS
  • Implemented ln=target for coloring links like their targets
  • Fixed the order of fallbacks used when some color keys are unset
• Add a workaround for incorrect file types for bind-mounted files on Linux (#37)

Version 1.3.3

• Fixed unpredictable behaviour for empty responses to -ok/-okdir caused by an uninitialized string
• Writing to standard output now causes bfs to fail if the descriptor was closed
• Fixed incomplete file coloring in error messages
• Added some data flow optimizations
• Fixed -nogroup/-nouser in big directory trees
• Added -type w for whiteouts, as supported by FreeBSD find
• Re-wrote the -help message and manual page

Version 1.3.2

• Fixed an out-of-bounds read if LS_COLORS doesn't end with a :
• Allowed multiple debug flags to be specified like -D opt,tree

Version 1.3.1

• Fixed some portability problems affecting FreeBSD

Version 1.3

New features:

• -acl finds files with non-trivial Access Control Lists (from FreeBSD)
• -capable finds files with capabilities set
• -D all turns on all debugging flags at once

Fixes:

• LS_COLORS handling has been improved:
  • Extension colors are now case-insensitive like GNU ls
  • or (orphan) and mi (missing) files are now treated differently
  • Default colors can be unset with di=00 or similar
  • Specific colors fall back to more general colors when unspecified in more places
  • LS_COLORS no longer needs a trailing colon
• -ls/-fls now prints the major/minor numbers for device nodes
• -exec ; is rejected rather than segfaulting
• bfs now builds on old Linux versions that require -lrt for POSIX timers
• For files whose access/change/modification times can't be read, bfs no longer fails unless those times are needed for tests
• The testsuite is now more correct and portable

Version 1.2.4

• GNU find compatibility fixes for -printf:
  • %Y now prints ? if an error occurs resolving the link
  • %B is now supported for birth/creation time (as well as %W/%w)
  • All standard strftime() formats are supported, not just the ones from the GNU find manual
• Optimizations are now re-run if any expressions are reordered
• -exec and friends no longer leave zombie processes around when exec() fails

Version 1.2.3

• Fixed test_depth_error on filesystems that don't fill in d_type
• Fixed the build on Linux architectures that don't have the statx() syscall (ia64, sh4)
• Fixed use of AT_EMPTY_PATH for fstatat on systems that don't support it (Hurd)
• Fixed ARG_MAX accounting on architectures with large pages (ppc64le)
• Fixed the build against the upcoming glibc 2.28 release that includes its own statx() wrapper
