I've stopped updating at 5.19 for everyday use. It's been the most stable for me so far. I wouldn't be in a hurry to update. If you find a stable version that works for you, unless an update provides something of particular interest to you, I'd hold fire until enough feedback was posted up. Alternatively I've two versions on seperate SD cards, stable for me and latest update. Latest update becomes stable when fully tested. You can see where I'm going with this.
