Official releases of GrapheneOS, a security and privacy focused mobile OS with Android app compatibility.
Pixel 4, Pixel 4 XL and Pixel 4a are end-of-life and shouldn't be used anymore due to lack of most security patches for firmware and drivers. We provide extended support for harm reduction with the displayed patch level frozen at the last obtainable value
Settings: remove Private DNS setting for secondary users since it's not currently per-profile like VPN configuration but rather is global like Wi-Fi configuration
Settings: remove connectivity check setting for secondary users
Dialer: disable false gesture detection for answering calls until the faulty implementation in the AOSP Dialer app is replaced
hardened_malloc: improve fatal error reporting to include the abort message in Android crash reports
Messaging: work around upstream null pointer exception bug
libvpx: apply patch for CVE-2023-5217 to the standalone AOSP libvpx library, which was already fixed in the 117.0.5938.140.0 release of Vanadium
Pixel 4, Pixel 4 XL: add upstream sensor-related app compatibility fix from the September release already included for other devices
The older Pixels (up to Pixel 5a) only get three years of security updates, and the 4a got released in August of 2020 (the non-a model even earlier), so... yes, its EOL now.
Pixel 6 and 7 series get five years of Security updates, and the upcoming 8 series is rumored to get seven years.
