Version 2.4

• Added the Oniguruma regular expression library as an (optional, but enabled by default) dependency (#81). Oniguruma supports more regular expression syntax types than the POSIX regex API, and often performs better. To build bfs without this new dependency, do make WITH_ONIGURUMA= to disable it. Thanks @data-man!

• Added support for the ed, emacs, grep, and sed regular expression types (#21)

• Before executing a process with -exec[dir]/-ok[dir], bfs now ensures all output streams are flushed. Previously, I/O from subprocesses could be interleaved unpredictably with buffered I/O from bfs itself.

Version 2.3.1

• Fixed the build on Debian kFreeBSD

• Fixed a crash on GNU Hurd when piping bfs's output

• Fixed a double-close() on non-Linux platforms if fdopendir() fails

• Reduced memory allocations on startup

Version 2.3

• More tweaks to PAGER and LESS handling for bfs -help (#76)

• Use 512-byte blocks for -ls when POSIXLY_CORRECT is set (#77)

• Implemented -files0-from FILE to take a list of '\0'-separated starting paths.
  GNU find will implement the same feature in an upcoming release.

• Added colors to -printf output (#62)

• Faster recovery from E2BIG during -exec

Version 2.2.1

• Fixed some incorrect coloring of broken links when links are being followed (-L)

• Made the tests work when run as root by dropping privileges.
  This may be helpful for certain packaging or CI environments, but is not recommended.

• Treat empty PAGER and LESS environment variables like they're unset, for bfs -help (#71).
  Thanks @markus-oberhumer!

• The soft RLIMIT_NOFILE is now raised automatically to a fairly large value when possible.
  This provides a minor performance benefit for large directory trees.

• Implemented time units for -mtime as found in FreeBSD find (#75)

Version 2.2

• Fixed -hidden on hidden start paths

• Added a Bash completion script. Thanks @bmundt6!

• Fixed rounding in -used. Corresponding fixes were made to GNU find in version 4.8.0.

• Optimized the open directory representation. On Linux, much libc overhead is bypassed by issuing syscalls directly. On all platforms, a few fewer syscalls and open file descriptors will be used.

• Implemented -flags from BSD find

Version 2.1

• Added a new -status option that displays the search progress in a bar at the bottom of the terminal

• Fixed an optimizer bug introduced in version 2.0 that affected some combinations of -user/-group and -nouser/-nogroup

Version 2.0

• #8: New -exclude <expression> syntax to more easily and reliably filter out paths.
  For example:

  bfs -name config -exclude -name .git
  

  will find all files named config, without searching any directories (or files) named .git.
  In this case, the same effect could have been achieved (more awkwardly) with -prune:

  bfs ! \( -name .git -prune \) -name config
  

  But -exclude will work in more cases:

  # -exclude works with -depth, while -prune doesn't:
  bfs -depth -name config -exclude -name .git
  
  # -exclude applies even to paths below the minimum depth:
  bfs -mindepth 3 -name config -exclude -name .git
  

• #30: -nohidden is now equivalent to -exclude -hidden.
  This changes the behavior of command lines like

  bfs -type f -nohidden
  

  to do what was intended.

• Optimized the iterative deepening (-S ids) implementation

• Added a new search strategy: exponential deepening search (-S eds).
  This strategy provides many of the benefits of iterative deepening, but much faster due to fewer re-traversals.

• Fixed an optimizer bug that could skip -empty/-xtype if they didn't always lead to an action

• Implemented -xattrname to find files with a particular extended attribute (from macOS find)

• Made -printf %l still respect the width specifier (e.g. %10l) for non-links, to match GNU find

• Made bfs fail if -color is given explicitly and LS_COLORS can't be parsed, rather than falling back to non-colored output

Version 1.7

• Fixed -ls printing numeric IDs instead of user/group names in large directory trees
• Cached the user and group tables for a performance boost
• Fixed interpretation of "default" ACLs
• Implemented -s flag to sort results

Version 1.6

• Implemented -newerXt (explicit reference times), -since, -asince, etc.
• Fixed -empty to skip special files (pipes, devices, sockets, etc.)

Version 1.5.2

• Fixed the build on NetBSD
• Added support for NFSv4 ACLs on FreeBSD
• Added a + after the file mode for files with ACLs in -ls
• Supported more file types (whiteouts, doors) in symbolic modes for -ls/-printf %M
• Implemented -xattr on FreeBSD
