Another March update

CalyxOS 4.7 - March 2023 Quarterly Platform Release and Security update is now available for the Pixels and the Fairphone 4

We test all builds before release, however we cannot test every single thing on every single device, it’d take too much time. That’s why we release the builds to beta first, and then to stable afterwards.

Unfortunately, due to a mistake we accidentally released a buggy update to stable for Pixel 6 Pro. A fixed build has since been made available. Our apologies for the incovenience.

Note

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 8 Pro, 8, Fold, Tablet, 7a, 7 Pro, 7, 6a, 6 Pro, 6, 5a (5G) 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.
Security Updates: The SHIFT6mq stock OS follows a different security update release schedule. The device is still supported by the manufacturer. 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End-of-life: The Pixel 4a (5G), 5, 4a, 4 XL, 4, 3a XL, 3a, 3 XL, 3 are no longer being updated by the manufacturer, so the CalyxOS releases for these devices only contain the fixes to the open source components, such as the OS code and the Linux kernel.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.
