![]() Each of these links to the main discussion thread on our discussion forum. The announcements are also posted from the Twitter account, on the official subreddit, and in the official GrapheneOS chat rooms including the dedicated #releases: room for release announcements. The main place to discuss the releases are the threads posted on our our discussion forum with the Announcements tag. A release announcement indicates that the source code tags are available and that the official builds will soon be pushed out via the Alpha channel. Releases are announced on this page and included in an atom feed usable from any standard feed reader app. 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. 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. Finally, the release is then pushed out via the Stable channel after being tested by some users using the Beta channel. The release is then pushed out via the Beta channel shortly afterwards. Releases are tested by the developers and are then pushed out via the Alpha channel. Verified boot and the hardware-backed keystore also act as a final layer of protection. The internal payload for update_engine is also signed, providing another layer of signature verification and downgrade protection. Downgrade attacks are also prevented, and downgrades cannot be done unless a special downgrade update package has been signed with the release key. The update packages have an internal signature verified by the update client (or recovery when sideloading). Update packages are not for performing the initial installation and you should ignore incorrect guides trying to use them to install the OS. ![]() Those aren't currently linked below but may be in the future once they're being used more consistently. The over-the-air updates use delta update packages when available. A full update package can upgrade from any past version to the new version. 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. The factory images are used for the initial installation and can be verified with signify. The code examples below show how to set attributes using the provided methods.These releases are available as both tags in the source code repositories and official builds. To set or remove attributes on a channel or a contact, use the Channel or Contact classes in our SDKs: Your dashboard and SFTP uploads are listed in Audience » Attributes » Upload History. You can click Download sample CSV file to see a formatted file. Go to Audience » Attributes » Upload Attribute Data.Prepare your CSV file using the guidelines in Attributes CSV Format.Additional fields indicate opt-in statuses, so that you can send messages to new channels generated from your CSV upload. Here, you’ll see sections on Automatic Updates, and Beta Updates. When using email or SMS identifiers in your CSV file, Airship registers new channels for addresses or MSISDN/sender combinations that are new to your project. Open the iPhone’s Settings app, click on General, then Software Update. Using a CSV fileįollow the steps in the SFTP tutorial, or follow the steps below for CSV upload in the Airship dashboard. Set attributes on channels or named users by uploading a CSV in the dashboard or using SFTP, or from our SDKs or Channels API. Use the attribute ID as the value for the key when setting or removing attributes. Trying to use a custom or predefined attribute that you haven’t yet set up in the dashboard will result in an error. You must define custom attributes or add predefined attributes in the dashboard before associating them with channels and named users.
