The most major change in Hmisc is that thanks to discussions with a highly respected, persistent, and convincing member of the R community, Hmisc no longer overrides [.factor to drop unused factor levels by default upon subsetting. You can get the old behavior at any time by typing dropUnusedLevels(). A message to that effect appears when you attach the package. Also Hmisc no longer overrides the interaction function, as the R builtin version provides the sep argument. In the next version, the summary.formula function will be updated to automatically drop unused levels when this is appropriate.
Some other key changes are the addition of bubble plot capability in xYplot and addition of the capability of csv.get to correct certain date formatting inconsistencies. sasxport.get now has keep and drop arguments to restrict attention to a subset of datasets when many datasets are being imported. Other changes include bug and documentation fixes.
