Changelog

**Device Specific Changes:** - Etude kernel: Op.11 No.4 * Linux 4.9.267 * some upstream fixes of cpufreq_stats * fixed an issue where the frequency of big CPU cores is locked to a maximum of 1286MHz; the frequency of the big cluster is supposed to be restricted under 1286MHz if you battery is at or below 10%, as part of Qualcomm's thermal mitigation, but on previous versions, the frequency restriction was not removed after the phone is charged above 10% * default to suspend to RAM instead of s2idle (suspend to idle) for around a 25% reduction of idle battery drain * DO NOT use a third party kernel without proper support for Pixel thermal hal - Adjusted thermal configs to delay CPU frequency drop and smoothen the thermal throttling curve - Implemented dynamic thermal profile to work with Pixel thermal engine * the option is accessible under Settings/Battery/Optimization profiles (in case you are wondering, they had no effect on PE11 before this change) * thermal configs are dynamically loaded on a per-app basis * only the gaming profile is available besides the default profile, because other use cases are covered well enough by the default profile * the gaming profile maintains CPU frequency at even higher temperature compared the default profile * surface temperatures are measured by an infrared thermometer with matching emissivity to ensure they stay below the allowed maximum values of continuously held electronic devices in IEC 60950-1 (2005) standard * thermal profile is NOT a replacement for proper cooling. If you want better performance, you should cool your device. - Eliminated all SELinux neverallows and cleaned up unneeded or broken sepolicy * the latest Riru installation should work now. Note that if you use any mods like this, you will not receive support from me - Updated telephony blobs from pyxis 21.3.31 to fix random qtibus crashes in the background - Went back to Secure Element 1.0 to work with the updated blobs - Stopped enforcing s2idle from userspace init script so the kernel can suspend to RAM for better idle battery drain - Cleaned some unused config overlays **ROM update highlights:** - April security update - Fixed the issue of weather information not showing up in "At a glance" on the home screen of Pixel Launcher - Improved Face Unlock. The issue of front camera being occupied should happen less frequently. Let me know if you still encounter it - Devices will only use dark boot animation from now on - Translation updates

Changelog

**Device Specific Changes:** - Etude kernel: Op.11 No.3 * Linux 4.9.263 * merged CAF tag `LA.UM.9.3.r1-01500-sdm845.0` * DO NOT use a third party kernel without proper support for Pixel thermal hal - Reworked auto brightness * smoothened auto brightness ramp up and ramp down animations. The auto brightness adjustment process should be more natural and less obtrusive * increased ambient light sensor debounce time. Short period of ambient light fluctuation no longer causes sudden brightness changes. - Merged a fix for inconsistent vsync timestamps which used to cause random screen tearing in UI rendering. You should see a noticeable increase in smoothness. - Display hal: skip validate after idle power collapse **ROM update highlights:** - Misc fixes
