The update addresses several issues and improvements across the supported Pixel lineup. Notably, it includes updates to the Linux kernel, with version 6.1 updated to revision 6.1.182 and version 6.18 updated to revision 6.18.39. These kernel updates bring the latest improvements from the GKI LTS branch.

The changelog highlights improvements to keyboard compatibility, specifically addressing issues with the Compose TextField. Additionally, the update preserves external service metadata during application info updates, resolving an upstream bug that was causing WebView crashes.

Release Process

GrapheneOS follows a structured release process to ensure stability. New versions are first tested by developers and pushed through the Alpha channel. After initial testing, releases move to the Beta channel for broader user testing. Only after passing both stages are updates made available through the Stable channel.

The system includes multiple layers of security for updates. Each package has an internal signature verified by the update client or recovery during sideloading. Downgrade attacks are prevented, and downgrades require special downgrade update packages signed with the release key.

Update Channels

While GrapheneOS primarily uses automatic over-the-air updates, full update packages are available for users who may never connect their devices to the internet. These full packages can upgrade from any past version to the new one. Delta update packages are used when available for over-the-air updates to reduce bandwidth usage.

The project emphasizes that update packages should not be used for initial installations, as they are designed specifically for updating existing installations. Users are advised to follow the official installation guide for proper setup.

Announcement and Support

Release announcements are made on the GrapheneOS website and distributed through various channels including their X account, Mastodon, Bluesky, subreddit, and official chat rooms on Matrix and Discord. Each announcement links to the main discussion thread on their forum.

The changelog is available as both a web page and an Atom feed for easy tracking of changes. For users seeking historical context, a legacy changelog page contains release notes from before the project's rebranding in 2018 and 2019.
