<p>Changes since the 2025020500 release:</p>
<ul>
<li>kernel (5.10, 5.15, 6.1, 6.6): zero memory in early boot in case it wasn't zeroed by the OS as part of a clean reboot or shutdown</li>
<li>kernel (5.10, 5.15, 6.1, 6.6): zero memory in early boot in case it wasn't zeroed by the OS as part of a clean reboot or shutdown since there isn't fully encrypted RAM with a per-boot key yet (this is implemented by Pixel boot firmware since April 2024 for booting into fastboot mode but not booting into the OS since they only partially implemented our January 2024 reset attack protection proposal)</li>
<li>kernel (5.10): update to latest GKI LTS branch revision including update to 5.10.234</li>
<li>kernel (5.15): update to latest GKI LTS branch revision including update to 5.15.178</li>
