This blog is updated daily.
A general description is here.
‘as<-()’ avoids an infinite loop when a virtual class comes between a
subclass and an actual superclass.
Fix level propagation in ‘unlist()’ when the list contains zero-length
lists or factors.
Fix S3 dispatch on S4 objects when the ‘methods’ package is not
attached.
Internal S4 dispatch sets ‘.Generic’ in the method frame for
consistency with ‘standardGeneric()’ (PR#16929).
Fix ‘order(x, decreasing=TRUE)’ when ‘x’ is an integer vector
containing ‘MAX_INT’. Ported from a fix Matt Dowle made to
‘data.table’.
