March 2024 Quarterly Platform Release & Security update

Changelog

Icon, font and shape customization is missing. Existing customizations should stay applied
Separate Wi-Fi and Mobile data tiles have been removed, use the unified Internet tile for both

These are the fastest to update for us because Google supports them and handles everything
We only had to make some minor changes to get them working

Google no longer supports Pixel 4a (5G) and 5, but they share code with the Pixel 5a, which got updates that needed to be tweaked.
Since we maintain the code for these devices, we had to do the device-specific changes and make sure everything was fine
Work in progress, tentative schedule below, if all goes well.

Android 14 has been in beta for these devices, except 4a for which it is stable
Google made a lot of changes in this update, which breaks telephony on these devices entirely
We’re looking into it and still figuring out what to do
We’ll keep posting updates here as we try things out and know

This was a big update, and Google is switching to a new development model for Android, called trunk-based development
This is why the build ID now starts with “AP1A”.
Instead of working on features for months and then releasing it all at once, they’ll constantly keep iterating on the code and avoid having one major release with too many big changes.
Previously, some new and upcoming features may not be present at all in the code releases.
Now, more of those upcoming features will be present in the code, just turned off via configuration flags. This makes it far easier to work on and manage those changes.
This development model is followed by many companies, including Google themselves for most of their other projects, and now Android is following it as well.
Hopefully for us this means that future releases don’t have too much turmoil, resulting in less work for updates. We’ll see how that pans out later in the year.

Over-the-air Updates: CalyxOS updates are delivered over-the-air (OTA) automatically, without any manual intervention needed. However, if you'd like to manually update your CalyxOS install, see OTA.
Security Updates: The Pixel 9 Pro Fold, 9 Pro XL, 9 Pro, 9, 8a, 8 Pro, 8, Fold, Tablet, 7a, 7 Pro, 7, 6a, 6 Pro, 6 contain the full security patch, as they are still being updated by Google.
Security Updates: The Fairphone 4, 5, Motorola moto g32, moto g42, moto g52 stock OS follows a different security update release schedule, which usually lags behind by a month or two compared to Pixels. The CalyxOS releases for it only contain the latest fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware get updates as soon as the stock OS update is available.
End-of-life: The Pixel 5a (5G), 4a (5G), 5, 4a, 4 XL, 4 are no longer being updated by the manufacturer, so the CalyxOS releases for these devices only contain the fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware no longer get updates.
