Firmware 4.4.4 beta

If I have the Tro.y and Bond Bridge Pro should I update from 4.5.8 to 4.5.10 or stick with the 4.5.8?

I would stick with the 4.5.8.

Now the stable firmware is 4.5.16. Still stuck with 4.5.8 or should I update to the new stable one or the new beta?

Also, any progress in compatibility with RC300 fireplace remotes?
