A general description is here.
‘mclapply()’ gets an option ‘affinity.list’ which allows more efficient execution with heterogenous processors, thanks to Helena Kotthaus.
If the option ‘setWidthOnResize’ is set and ‘TRUE’, R run in a terminal using a recent ‘readline’ library will set the ‘width’ option when the terminal is resized. Suggested by Ralf Goertz.
If multiple ‘on.exit’ expressions are set using ‘add = TRUE’ then all expressions will now be run even if one signals an error.
‘Writing R Extensions’ now mentions the macros ‘MAYBE_REFERENCED’, ‘MAYBE_SHARED’, and ‘MARK_NOT_MUTABLE’ that should be used by package ‘C’ code instead ‘NAMED’ or ‘SET_NAMED’.
Runing of finalizers after explicit GC request moved from the R interface ‘do_gc’ to the ‘C’ interface ‘R_gc’. This helps with reclaiming inaccessible connections.
‘help.search(topic)’ and ‘??topic’ matching topics in vignettes with multiple file name extensions (e.g., ‘*.md.rsp’ but not ‘*.Rmd’) failed with an error when using ‘options(help_type = "html")’.
