A general description is here.
The backtick may now be escaped in strings, to allow names containing them to be constructed, e.g. ‘`\``’. (PR#15621)
Using ‘Sys.setlocale’ to set ‘LC_NUMERIC’ to ‘"C"’ (to restore the sane behavior) no longer gives a warning.
‘deparse()’ now deparses complex vectors more accurately; they will now re-parse to the original values. (PR#15534, patch based on code submitted by Alex Bertram.)
