This blog is updated daily.
A general description is here.
Several influence measures for ‘"glm"’ objects have been updated to use Pearson residuals rather than deviance residuals (the latter are not unbiased) and to not use leave-one-out estimates of dispersion in models with fixed dispersion. Thanks to Ravi Varadhan for discussions and testing of these updates.
There is a new directory ‘tests/C++Standards’ which contains small packages which can be test-installed to check support for various C++ standards. This is principally for use on Windows as on a Unix-alike this partially duplicates tests done by ‘configure’ - although it can also be used to test the behaviour of ‘R CMD INSTALL’ on unsupported standards.
