Updating Rooted S3 from 10.1.0 to 10.1.2?

[Curado]

I have the RC version of CM 10.1.0. This was my first time rooted and installing a ROM. I love it, it is awesome, but I was wondering.... it gave me an notification few weeks ago that an update was available. First 10.1.1 then 10.1.2. But it says for Update types that Stable Only is selected. Since I am not on Stable 10.1.0 but on RC, can I not apply this update?
