hi all how i can update to the new ver 18.9.2 without loss data
i also want to know
Loss of data never happens when updating, but to be on the safe side make a backup copy of your Manager data (see https://guides.manager.io/8890). Then just install the new version.
yes thank you
But what new in this ver 18.9
That depends on what your old version was. Release notes are here: https://www.manager.io/desktop/releases/. But most releases do not include features noticeable by users, just internal improvements. Only new features or bug fixes are announced on that web page.
