CoreELEC 9.2.6 is a maintenance update that comes almost four months after version 9.2.5 to introduce ZRAM support into the Linux kernel, which should dramatically improve the performance.
ZRAM creates a compressed block device in RAM with on-the-fly disk compression, but it’s currently only supported on the Amlogic variant, not Amlogic-NG. This new point release to the 9.2 series also introduces some Bluetooth improvements, such as automatic connection after boot and automatic switching to Bluetooth audio devices. On top of that, it improves media handling and playback.
