A general description is here.
Offline help on a Unix-alike now works even if options "latexcmd" and "dvipscmd" contain spaces (e.g. "dvips -Pmy_printer").
Rounding error could affect window(extend=TRUE) when applied to monthly series. (PR#13272)
R_HOME/bin/helpPRINT.bat now contains an example of use with MiKTeX to produce a PDF version of the help file.
The C-level function consolecmd had been broken in non-Latin-1 single-byte locales in R 2.8.0 by changes intended to support the Japanese IME. This affected some menu items in Rgui (e.g. to source R files with non-Latin-1 names) and submitting commands from the script editor, but only in rarer languageencodings such as Central European, Greek and Cyrillic. (PR#13195, probably also PR#13120)
