This blog is updated daily.
A general description is here.
PCRE has been updated to version 7.8 (mainly bug fixes)
plot.ecdf() now defaults to pch=16 so as to better convey the left-closed line segments.
The default pkgType option for non-CRAN builds of R on Mac OS X is now correctly "source" as documented.
The default R_LIBS_USER path in AQUA builds now matches the Mac-specifc path used by the Mac GUI: ~/Library/R/x.y/library
as.list() applied to an environment now forces promises and returns values.
Promises capturing calls to sys.parent() and friends did not work properly when evaluated via method dispatch for internal S3 generics.
