Release Notes

Changes

sk is now beating fzf in interactive matching for time, peak memory usage and CPU usage ! See the benchmarks below for details, including a brief explanation of the benchmark itself.

This release brings multiple breaking changes, please read the following if you have doubts about the update.

Default to the Arinae matcher

The biggest change of them all is that the default algorithm is now Arinae, skim's latest and most performant algorithm, featuring typo-resistance. If you want to keep using SkimV2, pass --algo skim_v2 and please take the time to open an issue explaining why if possible.
This also makes the --scheme option available to the default matcher, allowing for more refined matching scenarii.

Default to non-typo resistant

Typo-resistant behavior is now disable by default, add --typos to your skim invocation or SKIM_DEFAULT_OPTIONS to get it back. Unless you were using the frizbee, fzy or arinae matcher, this should not impact you.

Removal of the `skim_v1` algorithm

The SkimV1 algorithm, skim's initial algorithm, has been deprecated for years now, and it has now been removed.

SkimItem index (library only)

SkimItem::get_index and SkimItem::set_index are gone, and all index handling is now done internally.

Benchmarks

This benchmarks runs the interactive interface in a tmux session, and waits for the UI to stabilize.
It uses a 10 million path-like ASCII items input file, and the query test.

v3.7.0

0ac1ac8

3.7.0 - 2026-03-08

Release Notes

This adds a new library API: Skim::run_items. Using this, you don't need to send the items, the library handles it for you.

Instead of writing this:

use skim::prelude::*;
let (rx, tx) = unbounded();

// We need MySkimItem to override the set_index/get_index methods
struct MySkimItem {
    value: String,
    index: usize
}

impl SkimItem for MySkimItem {
    // Implement the default members
}

tx.send(vec![Arc::new(MySkimItem { value: String::from("foo"), index: 0 }) as Arc<dyn SkimItem>, Arc::new(MySkimItem { value: String::from("bar"), index: 1 }) as Arc<dyn SkimItem>]);

let res = Skim::run_with(options, Some(rx));

You can simply write this:

use skim::prelude::*;

let res = Skim::run_with(options, ["foo", "bar"]);

It will automatically convert any iterator of by adding an index field and then send it, before running skim.

🚀 Features

Add scheme for better filepath matching in Arinae
Add Skim::run_items API

🐛 Bug Fixes

Use sum of scores in And engine
Correctly init rank for and engine

⚙️ Miscellaneous Tasks

Add gungraun benchmark

v3.6.0

600d788

3.6.0 - 2026-03-02

Release Notes

This version adds the Arinae algorithm as an option, run sk --algo arinae to use it !

Arinae is designed to become skim's default algorithm in the future.

Technically, it uses Smith-Waterman and a modified Levenshtein distance with affine gaps for scoring, as well as multiple optimizations (the main ones being a loose prefilter and checks for early dismissal of paths that cannot lead to the best match). It also forbids typos on the first char of the query.

In practice, it should feel close to FZY's scoring with typos disabled, but with a more natural behavior regarding typos as Frizbee or other algorithms.

These other algorithms usually work by allowing a set number of typos using 3D matrices for computations, the max-typos value being set based on the length of the query. In practice, that meant that tes will match exactly, but test will allow one typo, meaning that typing a single character will change the filtered items completely. This algorithm will instead penalize typos, not block them completely.

This algorithm does not aim to revolution anything, but it aims at making typo-resistant fuzzy matching feel more like an actual alternative to the current options (namely FZF and FZY), while maintaining per-item performance at least as good as the current algorithms.

🚀 Features

Merge ranks in AndOr engine matcher
Add Arinae algorithm (#990)
(shell) Colored history widgets & remove perl completely (#994)

🐛 Bug Fixes

Make sure we drop Skim before returning the output

💼 Other

Drop flake-utils, add formatter (#992)
