This blog is updated daily.
A general description is here.
The included version of PCRE has been updated to 8.35.
The Bioconductor ‘version’ used by ‘setRepositories()’ can now be set by environment variable ‘R_BIOC_VERSION’ at runtime, not just when R is installed. (It has been stated that Bioconductor will switch from version 2.14 to version 3.0 during the lifetime of the R 3.1 series.)
The default ‘version’ of Bioconductor for its packages has been changed to the upcoming ‘2.13’, but this can be set by the environment variable ‘R_BIOC_VERSION’ when R is installed.
