Switched from the Slow Ring to the RP Ring yesterday. Tonight I got an update which has taken me to this.

Was a pretty long procedure, around 1 hr 20 mins. Seems to be working OK up to now.
Interesting, version 18363.448.

Yeah, I didn't understand why they said 18363.418 when 18363.448 is the latest for RP.
