Tested 2.9e for one day and here's my results:

x6 RX 580 4GB Sapphire (Stable 188mh/s - same hashrate as 2.8c)
x6 RX 570 4GB Armor (Very unstable 185mh/s - lower hashrate than 2.8c and it was more stable compared to 2.9e)
x6 RX 570 8GB Sapphire (Stable 193mh/s - lower hashrate than 2.8c)

Experiencing high stale shares on my RX 570 Armor Rig which wasn't the case in version 2.8c

Hopefully next update will be better.
