Subject: [Rd] [RFC] A case for freezing CRAN
Message-ID: <53298CFB.8060406@vanderbilt.edu>

To me it boils down to one simple question: is an update to a package on 
CRAN more likely to (1) fix a bug, (2) introduce a bug or downward 
incompatibility, or (3) add a new feature or fix a compatibility problem 
without introducing a bug?  I think the probability of (1) | (3) is much 
greater than the probability of (2), hence the current approach 
maximizes user benefit.
