ChromeOS 133 Release Notes

Stable Channel

Released to stable on February 17, 2025

New accessibility feature, improved Bluetooth mic resolution, and wider language support now available in ChromeOS 133

Bounce Keys on ChromeOS

Bounce Keys is an accessibility feature designed to make computer use easier for individuals with limited dexterity or tremors. It works by ignoring repeated keystrokes within a short time interval, which you can customize to fit your needs. This prevents unintended characters being entered due to unintentional key presses.

New toggle for Bluetooth mic Super Resolution

ChromeOS 133 adds a toggle to control Bluetooth mic Super Resolution. The toggle is added in the audio setting page and is only visible when the feature is supported and the selected input device is a Bluetooth headset.
