The 4.14 series introduced several features that became critical for Android mobile performance: Version 4
specifically entered the Android ecosystem during the latter half of 2019, as a cumulative stable update that addressed several memory leaks, race conditions, and potential exploits discovered in earlier 4.14.x releases.
: Version 4.14 heavily optimized EAS. This feature fundamentally improved how Android distributes workloads across "Big" and "Little" CPU cores to save battery. What is New in Maintenance Release 4.14.117?
The era of the 4.14 kernel was heavily defined by hardware-level vulnerabilities, most notably Spectre and Meltdown. Version 4.14.117 included vital mitigations against speculative execution side-channel vulnerabilities impacting ARM Cortex processors.
