While perhaps I shouldn't be surprised, but even some simple, quick-and-easy descriptive commands in Stata have become a bit more complex. The up-side, however, is that these commands became a bit more powerful and useful as well.
One recent example is that, and helpfully described and summarized in a tutorial video (here), the standard sum command may now be overshadowed by a more flexible and powerful dtable command. One quite nice feature is that the dtable command includes sub-commands (e.g., tests) that will automatically subject variables to appropriate tests to generate p-values. Again, in all, these new features, while not earth-shattering, involve more efficient coding.
