<h1>Releases</h1>
<p>These releases are available as both tags in the source code repositories and
official builds.</p>
<p>The factory images are used for the initial installation and can be verified with
GPG. See the <a href="/install">installation guide</a> for details.</p>
<p>GrapheneOS uses automatic over-the-air updates, but full update packages are listed
below for uncommon use cases like never connecting the device to the internet. A full
update package can upgrade from any past version to the new version. The over-the-air
updates use delta update packages when available. Those aren't currently linked below
but may be in the future once they're being used more consistently. Update packages
are not for performing the initial installation and you should ignore incorrect guides
trying to use them to install the OS.</p>
<p>The update packages have a internal signature verified by the update client (or
recovery image when sideloading). Downgrade attacks are also prevented, and downgrades
cannot be done unless a special downgrade update package has been signed with the
release key. The internal payload for <code>update_engine</code> is also signed,
providing another layer of signature verification and downgrade protection. Verified
boot and the hardware-backed keystore also act as a final layer of protection.</p>
<p>Releases are tested by the developers and are then pushed out via the Beta channel.
The release is then pushed out via the Stable channel after being tested by some users
using the Beta channel. In some cases, problems are caught during Beta channel testing
and a new release is made via the Beta channel to replace the aborted one. In general,
it's not possible to downgrade unless a downgrade update package is generated, so use
the Stable channel if you cannot tolerate dealing with temporary issues while a new
release for the Beta channel is being created.</p>
