Updates tokenizers from 0.22.2 to 0.23.1

Release notes

Sourced from tokenizers's releases.

Release v0.23.1

TL;DR

tokenizers 0.23.1 is the first proper stable release in the 0.23 line — 0.23.0 only ever shipped as rc0 because the release pipeline itself was broken (Node side hadn't shipped multi-platform binaries since 2023, Python side was on pyo3 0.27 without free-threaded support). 0.23.1 is the version where everything actually goes out the door together: full Node multi-platform wheels for the first time in years, Python 3.14 (regular and free-threaded 3.14t), full type hints for every Python class, and a stack of measurable perf wins on the BPE / added-vocab hot paths.

There is no functional 0.23.0 published — we tag 0.23.1 directly so users don't accidentally pull a never-shipped version.

---

🚨 Breaking changes

• Drop Python 3.9 (#1952) — requires-python = ">=3.10"; 3.9 users stay on 0.22.x.
• add_tokens normalizes content at insertion (#1995) — re-saved tokenizer.json may differ in the added_tokens block. Existing files load unchanged.
• Type stubs are precise (#1928, #1997) — methods that returned Any now return real types; mypy --strict may surface previously-hidden errors. Stub layout also moved from tokenizers/<sub>/__init__.pyi to tokenizers/<sub>.pyi. This breaks the surface of some of the processors like RobertaProcessign's __init__ .
• 3.14t-only: setters/getters return PyResult<T> because of Arc<RwLock<Tokenizer>>; a poisoned lock surfaces as PyException instead of a panic.

---

⚡ Performance — measured locally on this Mac, not lifted from PRs

Run with cargo bench --bench <name> -- --save-baseline v0_22_2 on v0.22.2, then --baseline v0_22_2 on v0.23.1. Numbers are point-in-time wall clock on a single laptop; relative deltas are what matters, absolute numbers will differ on CI hardware.

Added-vocabulary deserialize — the headline win (#1995, #1999)

bench: improve added_vocab_deserialize to reflect real-world workloads (#2000) is now representative of how transformers actually loads tokenizer.json files. The combined effect of daachorse for the matching automaton plus the normalize-on-insert refactor is enormous on this workload:

benchmark	v0.22.2	v0.23.1	change
100k tokens, special, no norm	~410 ms	248 ms	−40%
100k tokens, non-special, no norm	~7.1 s	273 ms	−96%
100k tokens, special, NFKC	~395 ms	235 ms	−40%
100k tokens, non-special, NFKC	~7.4 s	290 ms	−96%
400k tokens, special, no norm	~15 s	980 ms	−94%

Real-world impact: loading a Llama-3-style tokenizer with a large set of added tokens dropped from "noticeable pause" to "instant".

BPE encode

benchmark	v0.22.2	v0.23.1	change
BPE GPT2 encode batch, no cache	530 ms	446 ms	−16%
BPE GPT2 encode batch (cached)	690 ms	685 ms	noise
BPE GPT2 encode (single)	1.95 s	1.94 s	noise
BPE Train (small)	32.6 ms	31.5 ms	−3%
BPE Train (big)	1.01 s	988 ms	−2%

The BPE per-thread cache PR (#2028) shows much larger wins on highly-parallel workloads (+47–62% at 88+ threads on a server box, per the PR's own measurements on Vera). Single-thread batch numbers above are flat or slightly improved because cache-hit overhead was already low without contention.

Updates gix from 0.81.0 to 0.83.0

Release notes

Sourced from gix's releases.

gix v0.83.0

Bug Fixes

• Correctly use $COMMON_DIR/info/exclude to make excludes work in worktrees. It turns out there is no per-worktree excludes file either.

Chore (BREAKING)

• Upgrade prodash and crosstermion to the latest version. This will fix the cargo deny issue as it brings in a newer lru crate.

Bug Fixes (BREAKING)

• remove winnow and replace it with hand-implemented parsers everywhere. This will allow for simplified maintenance and editing (both human and machine) down the road, and enable additional performance optimisations.

  Parser compbinators to me ultimately were a failed experiment as I couldn't maintain them anyway, with it being too difficult for me to grasp and express everything in its very own kind of language, with a lot of different things to consider.

  Note that this also removes detailed errors from all parsers that previously used winnow, with the option to re-add those if there is demand.

Updates fs4 from 0.12.0 to 1.1.0

Release notes

Sourced from fs4's releases.

v1.1.0

Changes

• Consolidate FileExt and AsyncFileExt into single crate-root traits (fs4::FileExt, fs4::AsyncFileExt) instead of generating a distinct trait per backend module. The per-backend modules (fs4::tokio, fs4::async_std, fs4::smol, fs4::fs_err2, fs4::fs_err3, fs4::fs_err2_tokio, fs4::fs_err3_tokio) now re-export the unified crate-root trait. Method-call sites that import the trait via use continue to compile unchanged; code that named two backend traits as distinct types will see them unify.
• Add blanket impls impl<F: FileExt + ?Sized> FileExt for &F and impl<F: AsyncFileExt + ?Sized> AsyncFileExt for &F, so the extension methods are now callable through shared references.
• Seal FileExt and AsyncFileExt via a private sealed::Sealed supertrait, so the set of implementing types is closed to the concrete file types fs4 already supports (and references to them). This locks in the freedom to add methods to either trait in future minor releases without breaking downstream impls.
• Add DynAsyncFileExt, an object-safe mirror of AsyncFileExt whose async methods return BoxFuture<'_, T> (alias for Pin<Box<dyn Future<Output = T> + Send + '_>>). Use it whenever type erasure is needed (Box<dyn DynAsyncFileExt>, &dyn DynAsyncFileExt); prefer the static AsyncFileExt for generic code since it has no allocation or dynamic-dispatch overhead. Every type implementing AsyncFileExt also implements DynAsyncFileExt, and the trait is sealed.
• Mark the delegating methods #[inline(always)] (skipped under tarpaulin coverage builds).

Breakage

• Renamed FileExt::lock_exclusive / AsyncFileExt::lock_exclusive to lock, matching the stabilized [std::fs::File::lock] API.
• Renamed FileExt::try_lock_exclusive / AsyncFileExt::try_lock_exclusive to try_lock, matching [std::fs::File::try_lock].
• Changed the return type of try_lock and try_lock_shared from std::io::Result<bool> to Result<(), TryLockError>. Ok(()) still indicates the lock was acquired; Err(TryLockError::WouldBlock) now indicates the lock is held by another handle. This matches the stable [std::fs::File::try_lock] signature (Ok(false) was the nightly shape prior to 1.89).
• Removed the top-level lock_contended_error() helper. Use TryLockError::WouldBlock instead.
• Flattened the fs_std module: th...
