The latest Karabiner-Elements beta can now show configuration diffs for troubleshooting. This required managing setting names as labels, so I took the opportunity to add localization support as well. It took some work, but the app is now fully available in Japanese.

Karabiner-Elements 16.3.0 is out 🎉 It mainly fixes a bug in 16.2.0's update check cycle, plus the remaining delays in key remapping after waking from sleep. I finally managed to reproduce and fix those delays. Personally, I'm glad to have this resolved. karabiner-elements.pqrs.org/docs/release...

The beta version of Karabiner-Elements includes improvements to inter-process communication, making it more robust and reliable. This change is intended to completely eliminate the rare issue where event modification fails to start because of communication errors.

I've confirmed Karabiner-Elements works properly on macOS 27 Golden Gate 🎉

I’ve added a filtering feature to the log viewer in the Karabiner-Elements beta. I should have added this much earlier.

I've published the release candidate for the next version to the beta channel. If nothing comes up, I plan to release it in a few days.

Takayama Fumihiko @pqrs.org · 21/04/2026

As a final touch for the Karabiner-Elements new release, I've added some improvements to the setup wizard. If testing goes well, I plan to proceed with the release.

020

Takayama Fumihiko @pqrs.org · 19/04/2026

The beta version of Karabiner-Elements already includes most of the features I want in the next release, so I'd like to release it soon, but I still want to tweak the post-installation wizard a bit more.

020

Takayama Fumihiko @pqrs.org · 22/03/2026

In the latest Karabiner-Elements beta, you can now use information about the focused UI element via the Accessibility API. Well-designed applications properly expose UI element information, so I hope more applications will support this correctly.

Takayama Fumihiko @pqrs.org · 07/03/2026

In the latest Karabiner-Elements repository, I've updated EventViewer to display the name of the device that sent the event. It's one of those changes that makes you wonder why it wasn't done earlier.

Now that JavaScript support in Karabiner-Elements has stabilized, I'm prioritizing JavaScript examples for expert configuration.

021

Takayama Fumihiko @pqrs.org · 04/02/2026

In the Karabiner-Elements beta, I made several fixes to the JavaScript support and have started migrating complex or special configurations to JavaScript rules. While this does assume some programming knowledge, being able to edit them easily from the settings UI is very convenient.

030

Takayama Fumihiko @pqrs.org · 03/02/2026

In the latest version of Karabiner-Elements (v15.9.5), you can now generate Complex Modifications JSON rules using JavaScript.

031

Takayama Fumihiko @pqrs.org · 01/02/2026

In the latest beta of Karabiner-Elements, you can now edit JSON using your preferred editor. This change is less about the current JSON itself and more about addressing the fact that the built-in editor is too limited for eventually defining configurations in JavaScript.

Karabiner-Elements 15.8.0 has been released. The removal of the probable stuck key detector is the major change in this version. In addition, another long-awaited improvement is that the Do Not Disturb key is finally supported. karabiner-elements.pqrs.org/docs/release...

Takayama Fumihiko @pqrs.org · 06/12/2025

I introduced a major change in the latest beta of Karabiner-Elements (v15.7.17). Since macOS 13 and later no longer misrecognize keys pressed before Karabiner-Elements seizes the device as held down, I removed the probable key stuck detector, which hurt usability.

There are plenty of features I want to implement, but without proper Liquid Glass support the UI breaks, so I've been focusing on full macOS 26 support.

040

Takayama Fumihiko @pqrs.org · 11/08/2025

It is a small thing, but in the beta I improved the UI overall: removed unnecessary padding, standardized inconsistent spacing, and increased the number of items visible at once.

The beta version of Karabiner-Elements brought major improvements, and I've now completed two of the most important goals: migrating to the SwiftUI life cycle and upgrading to Swift 6. With that done, development has reached a key milestone, and I'll start shifting focus to preparing for release.
