Juniper runs a quarterly (roughly major) 10.1, 10.2, 10.3, 10.4, ....

R is patch revisions for the major release. They are usually good at 
fixing and not breaking things on the R release. My last upgrade a bit 
ago was R7.5 of 10.4 (which has more revisions than older 10 releases, 
probably due to the fact that it will be the long term support release 
and gets non-critical patches as well).
