ChromeOS 121 Release Notes

Stable Channel

Released to stable on February 6, 2024

ChromeOS 121 reached stable release on February 6, 2024, bringing with it updates to App Streaming on Chromebooks, dictation, and ChromeOS Flex End of Life support.

Use ChromeVox when App Streaming on Chromebooks

When using App Streaming on Chromebooks, you can now use ChromeVox to navigate a streaming Android app. The Android app’s accessibility tree is streamed in tandem with the app itself and can be interacted with using ChromeOS screen reader capabilities.

Enable dictation using the keyboard

You can now enable dictation using search + d on your keyboard (or the dictation key on some Logitech keyboards). When enabling dictation, a dialog will appear to inform you that you are about to enable dictation, that certain speech files may be downloaded, and where to go to change your dictation language.


A ChromeOS desktop featuring an alert with the header ‘Turn on dictation.' The text reads: ‘You can type using your voice. To use dictation, press the dictation key or select the microphone icon at the bottom of the screen when you are on a text field. Your dictation language is English (United States). Speech files will be downloaded. To change dictation language, go to Settings > Accessibility > Keyboard and text input.' After the text, there are two prompts: ‘Cancel' and ‘Turn on'.

ChromeOS Flex End of Device support

As of January 01, 2024, support has been discontinued for the ChromeOS Flex devices that officially ended support in 2023. The devices will continue to receive ChromeOS Flex updates but these updates will no longer be tested or maintained by the Flex team.
