<h2><a href="#about-the-releases">About the releases</a></h2>
<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
signify. See the <a href="/install/">installation page</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 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>

<section id="release-announcements">
<h2><a href="#release-announcements">Release announcements</a></h2>
<p>Releases are announced on this page including via an atom feed, via our
<a href="https://twitter.com/GrapheneOS">@GrapheneOS Twitter account</a>, on the
<a href="https://reddit.com/r/GrapheneOS">official subreddit</a> and in the
official #grapheneos IRC channel on irc.freenode.net bridged with the
#grapheneos:matrix.org room on Matrix. A release announcement indicates that the
source code tags are available and that the official builds will soon be pushed
out via the Beta channel.</p>

</ul>
<p>Changes since the 2021.04.22.20 release:</p>
<ul>
<li>enable backup service for non-owner users so that secondary users can be backed up</li>
<li>add SetupWizard activities for secondary users including support for restoring backups</li>
<li>Settings (Accessibility): add Monochromacy (grayscale) option to color correction</li>
<li>improve the newer generation eBPF-based implementation of the INTERNET permission to properly support revoking the permission in secondary profiles (we'll be keeping our restoration of the much simpler non-eBPF-based approach to avoid relying on this on devices using our hardened kernels) </li>
<li>Vanadium: update Chromium base to 90.0.4430.91</li>
<li>Pixel 3, Pixel 3 XL, Pixel 3a, Pixel 3a XL, Pixel 4, Pixel 4 XL, Pixel 4a, Pixel 4a (5G), Pixel 5: set slot number for eSIM (still need an eSIM activation app since it's one of the remaining missing components from not including Google apps and services)</li>
<li>hardened_malloc: use 1 slot for all extended size classes (reduces memory usage and improves security in combination with the guard slab feature)</li>
<li>use device theme accent color for fingerprint dialog instead of teal</li>
<li>integrate modern Android theme and wallpaper configuration</li>
<li>remove legacy WallpaperPicker app</li>
<li>Updater: modernize update settings via androidx preference library</li>
<li>use alternate grapheneos.online domain for connectivity check / captive portal fallback URLs to improve handling of future issues comparable to Quad9 temporarily blocking grapheneos.network due to some kind of false positive</li>

<li>SELinux policy: disable gmscore_app domain</li>
<li>SELinux policy: use dedicated SELinux domain for Updater app based on the modern untrusted_app domain</li>
<li>stop disabling support for stable local privacy addresses since Android 11 handles it better by only using it when MAC randomization is disabled</li>
<li>update to a new version of Seedvault for Android 11</li>
<li>build and use otatools.zip for signing releases instead of an ad-hoc approach</li>
<li>Auditor: update to <a href="https://github.com/GrapheneOS/Auditor/releases/tag/19">version 19</a></li>

<p>Installations made before this project was renamed to GrapheneOS and before the
first official release of the Android Hardening project will be forced to factory
reset as part of this upgrade, due to lack of backwards compatibility with the
unaltered AOSP encryption format.</p>

<p>Testing the Android 11 kernels was useful, but we weren't able to ship the previous
release due to issues uncovered during testing. The Android 11 kernels have minor
backwards incompatible changes in the drivers for at least a subset of the devices so
we'll need to ship them with the rest of the changes. Thanks to our testers for
helping us with this. This will be the new final Android 10 release, assuming no
further problems are uncovered during testing.</p>
<p>Changes since the 2020.09.10.05 release:</p>
<ul>
<li>revert to using the Android 10 kernels on the devices that were switched over early due to backwards incompatible changes in some drivers</li>

<p>This should be the final GrapheneOS release based on Android 10. It ships the
device-independent monthly security patches and migrates over to using the Android 11
branch of the GrapheneOS kernels for most devices, which brings all the upstream
kernel hardening in Android 11 along with the full September kernel updates. The
remaining patches for the full 2020-09-05 patch level require finishing the migration
to Android 11 in order to ship the September update for the other device support code.
It's possible we could ship some of this early, but instead we're going to be focusing
on finishing the enormous task of migrating to Android 11. Further help with bringing
up support for the devices with Android 11 and porting over each of the GrapheneOS
hardening features to it would be greatly appreciated. Donations are also extremely
helpful. GrapheneOS has brought on another full time developer using donated funds and
there are 3 part time developers helping with Android 11.</p>
