(3) What was fixed by this version -- i.e. why the update.
(4) Link to firmware

Please read the FAQ

Thanks for all the great details. One question: can you bypass all the intervening updates and go straight from 2.20 to 2.25 or do you have to update 2.20 to 2.21 and then 2.21 to 2.23 etc. etc.?

[Andrew Pratt]

Yes you can just upgrade to the latest firmware and it will contain all the previous fix's
