[ChromeOS Update] The latest "M-148" is now available on the stable channel! ChromeOS Flex users should also check it out

Hello! Thank you for always reading our articles.

In this article, I will quickly and clearly explain the latest update information for ChromeOS / ChromeOS Flex announced by Google.

For those who are "reviving and using old computers" or "using a Chromebook as their main machine for work or study," this is important news regarding system stability and security. Please be sure to read until the end.

1. Overview of this update

On June 3, 2026 (local time), Google released a new version for the "Stable channel" of ChromeOS and ChromeOS Flex.

The main data for this update is as follows.

• Milestone: M-148

• ChromeOS Version: 16640.57.0

• Browser Version: 148.0.7778.250

What is the "Stable channel"?

It is the version that has been most thoroughly tested and is safe to use for daily work and in educational settings. It is the recommended channel for everyone who wants to use their PC as usual with fewer bugs.

2. Key points! Explanation and analysis

I have summarized the points to pay attention to in this update into two items.

1. "ChromeOS Flex" is also updated at the same time!

ChromeOS Flex, which can be installed and reused on old Windows or Mac computers, has also been updated to the latest version at the same time as regular Chromebooks. For those who are "reviving low-spec PCs for study purposes," it is a welcome point that the latest security environment is maintained.

2. Basically, you just need to "wait" for the automatic update

Stable channel updates are rolled out to your device over a period of several days to several weeks. Basically, they are downloaded in the background and applied when you are prompted to restart.

If you want to try it out as soon as possible, you can also update manually by following the steps below.

Settings > About ChromeOS > Check for updates

3. What if a problem occurs after the update?

In this release blog, Google has provided guidance saying, "Please let us know if you find any new issues."

If you feel that something is not working correctly after the update, you can send feedback using the following methods.

1. Report from the browser: Send feedback via the Chrome browser menu or the shortcut key (Alt + Shift + i).

2. Utilize the community: By checking the official "Chromebook Help Community" or similar, you can see if other users are reporting the same issue.

By gathering reports on bugs and issues, they will be fixed in the next minor update. This is also the secret to the speed of ChromeOS's evolution.

Summary: Stay simple, smart, and maintain the latest IT environment

This update marks the transition to a new milestone called "M-148," and includes security enhancements and performance optimizations in areas that are not visible.

The greatest strength of ChromeOS is that the OS continues to be updated regularly and remains lightweight, without the need to keep replacing high-spec, expensive PCs.

Keep your Chromebook or your Flex machine, reborn from an old PC, up to date, and have a comfortable IT life today!
