This blog is updated daily.
A general description is here.
New reference class utility methods ‘copy’, ‘getRefClass’ and ‘getClass’ have been added.
‘reshape’ now makes use of ‘sep’ when forming names during reahaping to wide format. (PR#14435)

Variable ‘FCLIBS’ can be set during configuration, for any additional library flags needed when linking a shared object with the Fortran 9x compiler. (Needed with Solaris Studio 12.2.)
‘qr.X()’ with column names and pivoting now also pivots the column names. (PR#14438)
‘unit.pmax()’ and ‘unit.pmin()’ in package ‘grid’ gave incorrect results when all inputs were of length 1. (PR#14443)
