X-T3 firmware 3.20 has been released.
August last year I upgraded from 2.10 to 3.00 to address a command dial issue on one of my XT3s. Everything was good, no specific reason to upgrade to 3.10 but I did last week to stay current.
3.10 was noticeably laggy and had focus hunting issues with both 23 1.4 & 56 1.2. I also noticed the camera grip heating up on one of the bodies a couple of days ago. Haven't used it much since so can't confirm it's ongoing or was incidental.
Haven't shot a frame with 3.20 but read reports it appears to have fixed the AF issues.
I suspect most users don't upgrade unless it's necessary. Have to echo that sentiment, if it ain't broke, don't upgrade.
Also wasn't aware that firmware downgrades aren't supported. I tried going back to 3.00. Not an option.
