This blog is updated daily.
A general description is here.
‘R CMD INSTALL’ no longer tangles vignettes. This completes an ‘R CMD build’ change in R 3.0.0 and affects packages built before R 3.0.2. Such packages should be rebuilt to have the tangled R code of vignettes shipped with the tarball.
‘R CMD build’ no longer fails if a package vignette uses child documents and ‘inst/doc’ exists. (Thanks to Sebastian Meyer's PR#18156.)
When an R documentation (‘help’ source) file ‘man/foo.Rd’ in a package has \donttest{..} examples with a syntax error, it is now signalled as ERROR and with correct line numbers relating to the ‘*-Ex.R’ file, thanks to Duncan Murdoch and Sebastian Meyer's reports and patch proposals in PR#17501.
‘R CMD Rd2pdf’ no longer leaves an empty build directory behind when it aborts due to an already existing output file. (Thanks to Sebastian Meyer's PR#18141.)
