This blog is updated daily.
A general description is here.
The PCRE library has been updated to version 8.00.
detach/unloadNamespace() arrange to flush the package's
lazyload cache of R objects once the package/namespace is no
longer needed.
R CMD INSTALL has new options --no-R, --no-libs, --no-data, --no-help, --no-demo, --no-exec, and --no-inst to suppress installation of the specified part of the package. These are intended for special purposes (e.g. building a database of help pages without fully installing all packages).
The treTRE library has been updated to version 0.8.0 (minor bugfixes).
rep(x, times, each=2) gave invalid results when the times
argument is a vector longer than x. Reported by Bill Dunlap.

There have been small fixes to the rendering of help, e.g. \command is now rendered verbatim (so e.g. -- is not interpreted, PR#14045).
Also, there are many small changes to help files where the new converters were not rendering them in the same way as before.
available.packages() could fail when run on a small repository (PR#14042).
rep(x, times, each=2) gave invalid results when the 'times' argument is a vector longer than 'x'. Reported by Bill Dunlap.
[g]sub(perl=FALSE, fixed=FALSE) could use excessive stack space when used with a very long vector containing some non-ASCII data strings.
