The new estat grangerplot command can now be used after didregress and xtdidregress to graphically assess whether treatment effects vary over time.

If you are using didregress or xtdidregress for difference-in-differences estimation and you are using the wild bootstrap to compute confidence intervals and p-values, you will now obtain results much faster. In addition, you can now perform the wild bootstrap in blocks if you need to improve memory use.
