New in the survey package

Version 4.5 of survey is on CRAN now. There are a lot of little changes and a few new features. Thanks to Stas Kolenikov we have Bell-McCaffrey standard errors for svyglm. The standard svyglm standard errors are based on sums of squares of PSU-level residuals. As Bell and McCaffrey point out These sums of squares tend to be too small for two reasons: residuals are generally smaller than true errors due to overfitting, and residuals tend to have lower intra-cluster correlation than the errors.
