Publishing chrome extension?

Question

Google Chrome

In the developer's office where extensions are loaded, messages hang

All bundled and hosted apps you publish after November 21, 2016 will only be available on Chrome OS. Previously published apps will continue to be available on all major platforms (Windows, Mac OS, Chrome OS, and Linux). They will also receive updates

What does it mean? The extension will not be available in chrome on windows or mac?

Answer 1
