Rust Coreutils 0.12.0 Release:
We are happy to announce the release of Rust Coreutils 0.12.0 - a release focused on compatibility fixes for our Ubuntu friends.
Ubuntu ships uutils coreutils as its default coreutils implementation, and this cycle was driven by what their users and maintainers reported: the bugs they asked us to prioritize are all fixed here, along with a long tail of smaller divergences from GNU. Few of these are glamorous, but they are exactly what breaks a script that has worked for twenty years.
Alongside that, we removed the last C dependency of expr (onig is replaced by the pure-Rust fancy-regex), continued the Windows port (nice, nohup and hostid now build there, and uucore's filesystem layer was rewritten with safe Win32 wrappers) and landed another round of security hardening on ls, sort and install.
Also, some contributions had carried comments and code over from GNU coreutils, against our own rule
that uutils is an original implementation. We reviewed the tree and rewrote what we found, in comments and in the few functions that followed the C too closely; no behaviour change. The GNU coreutils maintainers have been notified.
GNU coreutils 9.12 was released during our cycle (kudos to the team!), and some of the work went that way too. Chasing compatibility tends to turn up things worth fixing or improving on both sides.
We also made it official: a utility being significantly slower than GNU is now treated as a bug, not a wishlist item. If you hit one, please report it as a bug.
We are now at 653 passing, 21 failing, 0 errors on the GNU test suite.

> Note: the suite grew by 7 tests (backport of GNU tests) and 8 more tests are skipped on our reference runner, so the raw pass count is flat while the failures went down again. Counting only the tests that actually run, we are at 653/674 (96.9%), our best ratio so far, and the second release in a row with no erroring test. We are comparing against Coreutils 9.11.

Highlights:
- Ubuntu Compatibility
- The issues Ubuntu asked us to fix first are all fixed: data loss in a parallel install -D (#12355), du on 32-bit architectures (#11848), ls ACL dereferencing (#13234), cp -R name collisions (LP#2167118) and chmod -R through symlinks (LP#2167122)
- A whole family of options now accept a hyphen-leading value, like GNU does: csplit --suffix-format, paste -d, join -t, stat --format/--printf/-c and all of numfmt's options. A - in a delimiter or a format string is data, not a flag
- rm no longer segfaults on very deeply nested directories
- sort -n applies to the key instead of the whole line, echoes a disorder line verbatim instead of reformatting it as a number, and no longer keeps every input file open while sorting
- basename trailing-separator handling for dot components, realpath exit status in quiet mode, ln keeping the destination when a forced link fails, csplit always creating the final split even when empty, fmt -x/-X, printf treating a -- past the form

Rust Coreutils 0.11.0 Release:
We are happy to announce the release of Rust Coreutils 0.11.0 - a release focused on error messages, performance and GNU compatibility.
The big change is a new diagnostic engine built on ariadne. When a chmod mode, a cut list, a sort key or a tr set fails to parse, we now echo the arguments back with a caret under the character at fault, like a compiler does. See our blog post for more information: https://uutils.org/blog/2026-08-error-diagnostics/
Example with cut:
or test:
PGO release builds are enabled for Linux, macOS and Windows (up to 31% faster), and a lot of per-utility optimization work landed on top of that. We also now treat a utility being significantly slower than GNU as a bug.
We continued to improve the GNU compatibility and we are now at 653 passing, 22 failing, 0 errors.

> Note: 653 passing and 23 failing are both records for us, and this is the first release with no erroring test. Note that the suite grew by 2 tests this cycle (local backport). We also list the tests excluded from the pass/fail percentages now.

Highlights:
- Modern Error Diagnostics (new)
- A new diagnostic engine based on ariadne. When stderr is a terminal, a parse error is printed as a report: the arguments are echoed back as a source line, a caret marks the culprit and a help line explains the syntax. See the blog post for before/after examples
- Carets landed in chmod, mkdir, mkfifo, mknod, install, tr, expr, sort, numfmt, cut, env, head, tail, truncate, split, shred, stdbuf, od, seq, dd, stat, join, csplit, ls, df and du
- A caret can point inside a quoted argument and at a single character. The reports are localized (format, checksum and advice strings) and still print the usual Try '... --help' hint. A label is only added when it says something useful
- UUTILS_DIAG controls the behavior, and the caret rendering can be compiled out for size-constrained builds
- Diagnostics are written in a single stderr call, so concurrent writers cannot interleave them
- Performance
- PGO (profile-guided optimization) release builds: up to 31% faster - now enabled for the published Linux, macOS and Windows artifacts too.
- cp: opens the file only once (+32.93%) and reuses the already-open destination fd when a reflink clone falls back
- join: 1.37x faster on paired input, 2.5x faster than GNU, by skipping the locale comparison when it cannot change the result
- od --skip-bytes uses splice(2) on non-seekable input; tac uses fast_copy; dd no longer faults in the whole copy buffer before reading and page-aligns its read buffer
- Fewer allocations and syscalls in ptx (+4% via fxhash, plus fewer per-word allocations), nl (hoisted per-line prefix), tail (no double allocation per reverse chunk, no stat), expand/unexpand (no stat/is_dir), numfmt and sort
- New benchmarks for ptx, basenc and the numfmt stdin path
- A utility being significantly slower than GNU is now considered a bug - please report it as one
- GNU Co

Rust Coreutils 0.10.0 Release:
We are happy to announce the release of Rust Coreutils 0.10.0 - a release focused on GNU compatibility and robustness. The GNU test suite results improved sharply this cycle (645 passing, 29 failing, down from 56), we landed a second wave of security hardening (TOCTOU races, safe recursive descent, SELinux labeling at creation, backup guards), and we ran a broad anti-panic campaign across the utilities. On top of that: new features (mv --exchange, install --reflink, an OpenSSL backend for the checksum utilities), more zero-copy/read-ahead performance work, and wasm32-wasip2 support.

> Note: 0.9.0 bumped the GNU reference to 9.11, which added 25 new tests and temporarily pushed the failure count up. This cycle absorbed most of that debt: failures dropped from 56 to 29 and passes reached an all-time high of 645.
> As we contributed many tests to the GNU implementation, we are also the source of some of these regressions!

Highlights:
- GNU Compatibility
- 645 passing GNU tests (+20) and 27 fewer failures, the largest single-cycle drop we have had
- Dozens of behavior alignments: pr (-w/-W/-l/-e/-o, merge mode, page ranges), nproc (cgroups v2 quota, affinity mask, offline cores, OMP_* handling), date (out-of-range years, -d -, O modifier, timezone strings), numfmt, ls, du, install, od, truncate, fold, head/tail, sum, stat
- Many error messages now carry the file name and the real OS error instead of a vague or stripped message
- Security Hardening
- Continued the TOCTOU work started in 0.9.0: touch no longer uses O_TRUNC on create, mkfifo drops the path-based chmod, head checks the open fd instead of the path, split hardens the output-open path, chcon anchors recursive relabeling to the traversal dirfd
- Safe recursive descent fixes for chmod/chown (symlink cycles, --preserve-root re-checked during the descent), and cp no longer descends into a destination subdirectory that is a symlink
- SELinux labels are now applied at creation in mkdir, mkfifo and mknod instead of being applied afterwards
- mv fails closed when recreating a cross-device directory destination, compares file identity in the --backup=simple guard, and strips setuid/setgid when a cross-device copy cannot preserve ownership
- chroot chroots exactly the path --skip-chdir validated; stdbuf refuses a libstdbuf path that cannot be represented in LD_PRELOAD; install finalizes ownership before mode
- Added SECURITY.md documenting our threat model, scope and reporting process
- Robustness: Anti-Panic Campaign
- Removed panics and aborts across a long list of utilities: shuf, printf, numfmt, fmt, pr, chroot, dircolors, install, ln, touch, stat, split, expand, more, kill, cp, du, rm, runcon, sort, chown/chgrp, dirname, expr, cksum, dd, truncate, hashsum
- Recurring classes fixed: write failures on /dev/full, char-boundary panics on multibyte input, integer overflow on extreme widths/precisions/sizes, and unbounded allocations for huge arguments
- expr now uses an iterative p

Rust Coreutils 0.9.0 Release:
We are excited to announce the release of Rust Coreutils 0.9.0 - a release focused on safety and security. This cycle was shaped by a third-party security audit, driving extensive TOCTOU hardening and a sustained, project-wide effort to shrink the amount of unsafe code by removing it outright and migrating low-level syscalls from nix/libc to rustix. On top of that, we landed major zero-copy I/O performance work (splice/tee/pipe), broadened WebAssembly, Cygwin and Windows support, and continued contributing tests and bug reports upstream to GNU coreutils.

> Note: The rise in failing tests is due to the upstream GNU test suite being extended, not to regressions on our side. We updated our GNU reference from 9.10 to 9.11 (PR #11922), which added 25 new tests (665 → 690). Many of these newly-introduced tests are not yet passing, which accounts for the jump from 21 to 56 failures; no previously-passing functionality regressed, and work is ongoing to address the new tests.

Highlights:
- Security Hardening (Zellic audit)
- A third-party security audit by Zellic reviewed the codebase; the findings - widely reported as 44 CVEs (see also the Ubuntu update and the corrode write-up Bugs Rust won't catch) - were concentrated in TOCTOU races and filesystem edge cases that Rust's type system does not prevent
- It's worth noting that many of these CVEs are not memory-safety issues but differences in behavior from GNU coreutils that the audit identified; aligning our semantics with GNU resolves them
- This release closes many of them: a new TOCTOU-resistant uucore::safe_copy module; TOCTOU fixes in cp, mv, and chmod recursive traversal; rm dot/dotdot path-parsing protection; nohup.out now created with mode 0600; and chroot now resolves all ids before chrooting
- Reducing unsafe & migrating to rustix
- A sustained, project-wide push to shrink the unsafe surface: dozens of unsafe removals across utilities, tests, fuzz targets and uucore (get_groups, make_fifo, build.rs, and more)
- Migration from nix/libc to rustix across id, tr, timeout, sort, wc, tail, cp, who, factor, and core process/IO paths
- Performance: zero-copy I/O
- splice()/tee()/pipe() fast paths landed across cat, wc, head, tail, yes, cp, tee, and unexpand (e.g. unexpand +7.5%, faster cp from a pipe on Linux, tee via raw syscalls, yes using the tee syscall)
- Consolidated in a reworked uucore::pipes / buf_copy
- GNU Compatibility & Upstream Collaboration
- Reference bumped to GNU 9.11, which extended the suite with 25 new tests (the reason the failure count went up - see the note above; it is not a regression)
- We continue to contribute tests and bug reports upstream to GNU coreutils, and our compatibility work keeps surfacing edge cases on both sides
- New fixes across numfmt, date, tr, cksum, factor, head, stat, and sort
- numfmt Overhaul
- Precision handling, rejection of scientific notation, LC_NUMERIC decimal separator, zero-padding for negative numbers, IEC precision cap, large %f values, --to

Rust Coreutils 0.8.0 Release:
We are excited to announce the release of Rust Coreutils 0.8.0 — a major release featuring significant performance gains across core utilities, expanded WebAssembly (WASI) support with a brand-new online playground, and continued hardening against edge-case panics, /dev/full aborts and start of a large-scale migration from nix to rustix** for lower-level syscall safety!

📦 Rust Coreutils 0.0.30 Release:
We are excited to announce the release of Rust Coreutils 0.0.30!
Highlights:
- Improved Compatibility:
- This release focused on compatibility with the upstream GNU Coreutils 9.6 release. This is why the number of passing tests didn't change much - our effort was directed at adapting to the new upstream version rather than fixing existing test failures.
- Passing GNU tests increased to 507 (+1 compared to 0.0.29).
- Contributions: This release was made possible by the dedication of 22 contributors, including 8 newcomers.
- We also announced at FOSDEM the extension of this project to cover other key Linux tools through our uutils initiative. This will extend the Rust rewrite effort to additional common Unix tools. See the presentation on YouTube (slides) or read the LWN article for more details about our vision.
