The R core group has quickly followed up with a patch to R version 3. Announced yesterday, R 3.0.1 (code name: “Good Sport”) improves serialization performance with big objects, improves reliability for parallel programming and fixes a few minor bugs.

The R core group continues to develop R version 3, and more patches can be expected over the coming year. Revolution R Enterprise will update to inclde R version 3 in late 2013.
