This blog is updated daily.
A general description is here.
The cairo-based versions of ‘X11()’ now work with current versions of cairographics (e.g. 1.12.10). (PR#15168)
A workaround for earlier versions of R is to use ‘X11.options(type = "nbcairo")’.
The ‘configure’ tests for Objective C and Objective C++ now work on Mac OS 10.8 with Xcode 4.5.2 (PR#15107).
‘aperm(matrix(1:6, 2, dimnames=list(A={}, B={})), "A")’ no longer segfaults.
