2.4.1
-----

**February 24, 2022**

- Fixed the build when Oniguruma is not installed in the default search paths ([#82])

- Fixed string encoding bugs with Oniguruma enabled

- Fixed regex error reporting bugs

[#82]: https://github.com/tavianator/bfs/issues/82


2.4
---

**February 22, 2022**

- 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.

2.3.1
-----

**January 21, 2022**

- 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


2.3
---

**November 25, 2021**

- 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`

2.2.1
-----

**June 2, 2021**

- 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])

2.2
---

**March 6, 2021**

- 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


2.1
---

**November 11, 2020**

- 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`


2.0
---

**October 14, 2020**

- [#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
