LOS for microG just had an OTA update less than two weeks ago.There's also official e/OS based on Pie. Last build was from 15th August it seems. ROMs based on 4.9 kernel are superior to the old ones based on the stock 3.18 kernel. Already a couple of A12 ROMs available. But for the 2GB variants Pie ROMs are better from a multitasking POV esp. alongwith the low RAM mod.
I'm not a fan of /e/ because updates are slow and they bundle too many apps that I will never use.
I use a 2GB land variant, so I don't think the latest ROMs by sairam60 will work well on there. Just want something stable and with OTA as this isn't my primary device.
