Updates

How Luma updates itself, how to install an update right away, and how to get beta versions.

Luma keeps itself up to date. You don’t need to download anything: new versions arrive on their own and install when Luma closes.

How updates arrive

Half a minute after Luma starts, and then every hour, it checks lumabrowser.dev for a new version. If there is one, it downloads it in the background while you browse.

Before anything is installed, Luma checks that the update is signed with Luma’s own key, that it comes from lumabrowser.dev, and that the file is exactly the one that was signed. An update that fails any check is thrown away, and the version you have stays as it is.

Install an update

When an update is ready, Luma shows it in a place that depends on your layout:

  • With the sidebar: an Update ready card at the bottom of the sidebar, with the new version number and a Restart button.
  • With tabs on top: a Restart to update button in the toolbar, after the address bar.
  • In the dock: a Restart button among the tools at its end (just an icon when the dock is on a side).

You then have two choices:

  • Click the button. Luma closes, installs the update and opens again with your tabs.
  • Carry on. The next time you close Luma, the update installs quietly, and the new version starts the next time you open it.

If Luma was installed for all users of the PC, Windows asks for administrator permission when the update installs. If you refuse, Luma asks again the next time you close it. When Windows is shutting down or restarting, Luma waits and installs the update the next time you close it yourself.

Check by hand

  1. Open the ⋯ menu and choose About Luma.
  2. Under Updates, click Check for updates.

The same row tells you what is happening: Luma is up to date, a download in progress, or Version … installs when you restart. If you don’t see the button, look here. Settings › Advanced also shows the version you have and the Chromium version it is built on.

Beta versions

Turn on Get beta versions in Settings › Advanced to receive new versions before they are released. They can have bugs: tell us about them on the Discord. The change applies at the next check.

Turning beta versions off doesn’t take you back to an older version: you simply move on to the next regular release once it is newer than the beta you have.

What’s new

The first time Luma opens after an update, it tells you what changed. With the sidebar, a card at its foot lists the changes: click Got it to close it, or Join the Discord, where release notes come out first. In the other layouts, and in compact mode, a message says Luma has been updated to …: its What’s new button opens the changelog in a new tab.

You can look again whenever you like with ⋯ › What’s new in Luma. All past versions are on the changelog.
