This blog is updated daily.
A general description is here.
Support for very old versions of ‘valgrind’ (e.g. 3.3.0) has been removed.
A ‘coef()’ method for class ‘"maov"’ has been added to allow ‘vcov()’ to work with multivariate results. (PR#16380)
Header ‘Rconfig.h’ now defines ‘HAVE_ALLOCA_H’ if the platform has the ‘alloca.h’ header (it is needed to define ‘alloca’ on Solaris and AIX, at least: see ‘Writing R Extensions’ for how to use it).
