This blog is updated daily.
A general description is here.
‘Rcomplex’ definition has been extended to prevent mis-compilation when interfacing with Fortran (PR#18430). The new definition causes compiler warnings with static initializers such as ‘{1, 2}’, which can be changed to ‘{.r=1, .i=2}’. The new definition depends on C++ compiler extensions supporting C features that haven't been incorporated into the C++ standards, which may result in C++ compiler warnings.
New generic ‘.AtNames()’ added to enable class-specific completions after ‘@’. The formerly internal function ‘findMatches()’ is now exported, mainly for use in methods for ‘.DollarNames()’ and ‘.AtNames()’.
